What is the process that should take place if an opportunity arises that is more important than the work selected by the Team for the Sprint?
The Product Owner and Team can terminate the Sprint and conduct a new Sprint Planning Meeting. Assuming the new opportunity is the top priority in the Product Backlog, it is selected for the upcoming Sprint.
The Scrum term for the mechanism that coordinates multiple teams working on a single project is ________________.
The Scrum term for the mechanism that coordinates multiple teams working on a single project is Scrum of Scrums.
True or False: The same individual can serve as Product Owner and Scrum Master.
False. The Scrum Master should never serve as the Product Owner. Reasons:
- Being a ScrumMaster is a full time job.
- The Scrum Master supports the team while the Product Owner represents the clients' needs. At times these roles may come into conflict because often what the client wants and what the Team can accomplish within the Sprint are different. Therefore, the Scrum Master needs to have the role, when necessary, of pushing back on some of the Product Owner's requests.
- It is hard to facilitate (Scrum Master) when you also are the person also responsible for priorities (Product Owner). Even if you are good at it, team members may think that your question/request as a ScrumMaster is an order/direction from the Product Owner.
Describe the Scrum practice of Sashimi.
Sashimi stipulates that every slice of functionality created by developers is complete. That is, all requirements gathering and analysis, design work, coding, testing, and documentation that constitute the functionality are completed in the Sprint and demonstrated in the Sprint increment of functionality.

XP planning addresses two key questions in software development:
1. Predicting what will be accomplished by the due date 2. Determining what to do next.
What are the 2 key planning steps in XP?
The 2 key planning steps in XP are
1. Release Planning 2. Iteration Planning
What happens during XP Release Planning?
In XP Release Planning, the Customer presents the desired features to the programmers, and the programmers estimate the features' difficulty.
What happens during XP Iteration Planning?
In XP Iteration Planning, the following happens:
1. The Customer presents the features desired to be completed during the upcoming 2 weeks. 2. The programmers break these features down into tasks and estimate their cost. 3. Based on the amount of work accomplished in the previous iteration, the team signs up for what will be undertaken in the upcoming iteration.
What is the role of the XP Customer in acceptance testing?
The XP Customer defines one or more automated acceptance tests to show that the feature is working.
What is the role of the XP Team in acceptance testing?
The team builds the automated acceptance tests (defined by the Customer) and uses them to prove to themselves, and to the customer, that the feature is implemented correctly.
Why is automated testing important in XP and other Agile practices?
Automated testing is important because when time is pressing, teams tend to skip manual tests.
In what 2 important ways do XP teams practice small releases?
XP teams practice small releases in the following two ways:
1. The team releases running, tested software, delivering business value chosen by the Customer, every iteration. This software is visible and given to the customer at the end of every iteration.
2. XP teams release frequently to the end users. Web projects, for instance, release as often as daily.
What are some of the problems caused by infrequent integration?
Infrequent integration on a software project can lead to the following problems:
- Although integration is critical to shipping good working code, the team is not practiced at it, and often it is delegated to people who are not familiar with the whole system.
- Infrequently integrated code is frequently buggy. Problems creep in at integration time that are not detected by any of the testing that takes place on an unintegrated system.
- Infrequent integration leads to long code freezes during which the programmers cannot work on important shippable features.
True or False: Programmers in an XP project may not make changes to each others' code.
False. In XP, any pair of programmers can improve any code at any time during a project.
In XP, what are the 2 main advantages of allowing programmers to improve one another's code at any time during a project?
Allowing programmers to improve one another's code has the following advantages:
- Many people are paying attention to the code, which increases code quality and reduces defects.
- It leads to better cohesion. When code is owned by individuals, required features are often put in the wrong place, leading to ugly, hard-to-maintain code that is full of duplication.
What 2 XP practices prevent programmers from blindly working on code that they do not understand?
XP avoids the problem of programmers blindly working on code that they do not understand by the following:
- Programmer tests catch mistakes.
- Pair programming allows a programmer who is unfamiliar with code to work side-by-side with an expert.

Dividing large groups into smaller Scrum teams and designating one member of each team as an ambassador to participate in a daily meeting with ambassadors from other teams is called Scrum of Scrums.
What three environmental considerations need to be addressed prior to scaling a Scrum project?
To successfully scale a Scrum project, the following must be in place:
- An appropriate infrastructure so that work across multiple teams can be synchronized. - A more detailed product and technical architecture so that the work can be cleanly divided among teams. - Alternate communications, such as instant messaging, since multiple teams will not always be able to communicate face to face.
Setting up the infrastructure, technical architecture, and communications channels prior to scaling a Scrum project occurs when?
Setting up the infrastructure, technical architecture, and communications channels prior to scaling a Scrum project occurs during Sprints.
When preparing to scale a Scrum project, why is it important to set up the needed infrastructure during Sprints while at the same time developing shippable functionality?
When preparing to scale a Scrum project, it is important to set up the needed infrastructure during Sprints while at the same time developing shippable functionality. This allows the team to test the infrastructure with functionality development work as it evolves. It also demonstrates business functionality that enables results, thus keeping stakeholders engaged in the project.
When preparing to scale a Scrum project, nonfunctional requirements for this scaling take what priority in the Product Backlog?
When preparing to scale a Scrum project, nonfunctional requirements are a high, or even top, priority in the Product Backlog because they must be completed before scaling begins. They share high priority with business functionality.
What is a nonfunctional requirement?
A nonfunctional requirement specifies criteria that can be used to judge the operation of a system, rather than specific behaviors of the system. The following are examples of nonfunctional requirements:
The process of defining and prioritizing nonfunctional requirements for scaling a Scrum project is called
a. Staging b. Decomposing c. Iterative Scaling
The process of defining and prioritizing nonfunctional requirements for scaling a Scrum project is called
When preparing to scale a Scrum project, Staging occurs when?

A project is particularly suited for Agile when
1. there is a high level of internal uncertainty 2. the scope isn't well defined at the start of the project 3. the product benefits from ongoing customer feedback
What is meant by "internal uncertainty"?
Internal uncertainty refers to uncertainty on the part of the project manager and team about what a project will involve and about aspects of the project such as its schedule, resources, and cost.
True or False: Agile is appropriate for projects involving highly creative work.
True. Agile is especially appropriate for projects involving highly creative work, especially where customers aren't sure at the outset what they want.
True or False. Agile is appropriate for ground-breaking projects involving the development of completely new products or features.
True. Agile is appropriate for ground-breaking projects involving the development of completely new products or features. That's because this type of project involves a high level of internal uncertainty, and the lack of a well defined scope.
True or False: Agile is a good choice for a project that has a well established process and outcome.
False. In a project that has a well established process and outcome, the team will most likely be better off following a prescriptive plan based on the process and outcome of similar projects.
What does a project's criticality refer to?
Criticality refers to the severity of the impact its failure could have on the organization running it and on others, including end users.
True or False: It can be difficult to use an Agile approach in projects including safety and security requirements.
True. It can be difficult to use an Agile approach in projects including safety and security requirements because these requirements likely cannot be changed. However, applying Agile practices to such a project can be done; the project manager and team would need to recognize up front that some requirements are fixed.
True or False: A building-construction project with a specific scope lends itself well to Agile.
False. Construction projects depend on clearly formulated project plans in which each phase builds on the previous phase, and safety and security is key.
However, Agile could be used at the architectural-design phase.
Why is a hierarchical organizational structure not well suited to Agile?
A hierarchical organizational structure not well suited to Agile because it restricts open communication and rapid response to change. Employees are expected to follow orders, and their work is finely managed.
What are the main characteristics of a cooperative organizational structure?
In a cooperative organizational structure, employees work on teams, and collaboration is encouraged. This structure lends itself well to Agile.
Which type of organizational structure is best suited to Agile methodologies?
The project-based organizational structure is best suited to Agile methodologies because business- and project-related decisions are integrated, making the organization more flexible to any external change. This structure also encourages the organization to build its portfolio based on the strengths of its employees. Employees are motivated because they feel that they are contributing directly to the success of the organization.
How does requirements management affect the ability to adopt Agile processes?
If an organization's requirements management process is flexible and informal, it will be easier to adopt Agile processes. Rigid requirements management processes with highly detailed documentation will make it more difficult to adopt Agile.
How does configuration management affect the adoption of Agile?
Agile methodology will be easier if a system for configuration management is already in place but associated processes are flexible. Agile supports configuration management by requiring strict code versioning and strict build-and-release versions. However, it is flexible regarding document and baseline control.
What team characteristics should be considered when thinking of adopting Agile?
When thinking of adopting Agile, consider
- team size - team skills and experience - team members' locations
Agile is most suitable for teams of what size?
Agile is most suitable for small teams of up to 15 members. Some methodologies are scalable however, allowing for the division of larger teams into sub-teams.
List the 4 steps, in order, in the Agile process for defining requirements.
Agile uses the following 4 steps in defining requirements:
1. Describe the need for the product. 2. List required features. 3. Prioritize the requirements. 4. Refine the requirements.
Describe the MoSCoW Technique.
Using the MoSCoW Technique, the customer groups requirements into 4 categories: 1. Must have: Crucial features 2. Should have: Important features, but possible to implement short-term workarounds 3. Could have: These features can be left out of a release if the team runs out of development time. 4. Would have: Desired features, but marked for probable inclusion in a later release.
Iterative means involving repeated cycles.
Incremental means divided into a series of stages, each stage building on the last.
When determining what to develop in each Iteration, what 3 things should you consider?
When planning an Iteration, you should consider:
- Importance to Customer: What features are the most important to the customer, and work on them in the earliest Iterations. - Risk: Focus on the uncertain elements in a project first so that there is plenty of time to resolve these. - Architecture: The architecture or design of a product may make it necessary to complete certain development tasks in a certain order.

- Some programmers have a strong preference for working alone. - It can increase costs since 2 or more programmers will be working on the same code, thus possibly slowing productivity.
In XP, what is the Planning Game used for?
In XP, the Planning Game is a structured approach for determining which functionalities to develop over a set of successive iterations.
In the Planning Game, from where is the word "Game" derived?
"Game" is derived from economics: Actions taken by players, with the payoffs depending on the actions of all players.
What is the customer's role in the Planning Game?
In the Planning Game, the customer
1. expresses the requirements in the form of stories, written on story cards. 2. prioritizes the cards, specifying the order in which each functionality should be developed -- this is done after the developers estimate the time required to build each functionality.
True or False: Lean prescribes specific processes for carrying out development work that eliminate waste, achieve flow in the value stream, and make continuous improvements.

What are the common forms of waste in IT projects?
In IT projects, common forms of waste are:
- unnecessary processes, such as using detailed time sheets; burdensome, elaborate signoff forms; and unnecessary or badly run meetings. - production delays, such as waiting for code to be deployed and waiting for management signoff on tasks - incomplete work, such as code that hasn't been integrated, code that's waiting to be tested, and work started and then abandoned because of new decisions about what's required - multitasking, because switching tasks requires a change of focus and time to adjust
What are the 2 types of integrity in software development?
The 2 types of integrity in software development are
1. Perceived 2. Conceptual: This is judged by developers. Conceptual integrity is high if the different components of a product integrate well to provide a reliable, smooth-running system that fulfills its purpose.
What does Perceived Integrity refer to in software development?
Perceived Integrity depends on the customer's perceptions. It is high if the customer is happy with the product because it meets requirements, is highly usable, and is of good quality and value.
What does Conceptual Integrity refer to in software development?
Conceptual Integrity is judged by developers. It is high if the different components of a product integrate well to provide a reliable, smooth-running system that fulfills its purpose.
The customer is happy with the new training system your team has built. The system has a friendly, easy-to navigate user interface, it meets accessibility requirements, and it addresses the needs of different types of learners. The system was deployed by the agreed time and within cost constraints. This is an example of what type of software Integrity?
This is an example of Perceived Integrity, which depends on the perceptions of the customer. In this case, the customer is happy with the product because it meets requirements, is highly usable, and is of good quality and value.
Lean development follows a systems-thinking approach. What does this mean?
A systems-thinking approach means that all developers must focus on the system as a whole and how its parts will integrate rather than focusing on their own specialized components or modules.
True or False: Because Lean software development focuses on streamlining development and eliminating waste in the development process, most testing occurs at the unit, or component level, where the testing procedure is simplest.
False. Lean software development emphasizes "seeing the whole." Ongoing testing must occur at the system level as well as at the unit or component level. This helps ensure that developers focus on the total functionality of the system rather than just on its parts and that systems integration problems are discovered and fixed early on so that they don't delay the release of a system.
True or False: In Lean software development, developers are encouraged to assist other coders once their work is completed. Running tests, however, is handled by specified testers to ensure that both unit and system testing is done using a consistent process. This in turn ensures that undiscovered coding and integration problems do not delay the release of a system.
False. Lean software development focuses on "seeing the whole." As part of this, developers are encouraged, once their work is completed, to assist other coders whose work is proving to be more complicated or longer to finish. Developers who finish their coding may also assist with testing rather than moving on to developing other code -- this can alleviate work backing up and delays.
In Lean software development, why is the practice of "deciding late" important?
Lean development encourages late decisionmaking, with decisions delayed until the last possible moment. This is because of the following:
- Customers may change requirements often, making early decisions, and work based on them, no longer applicable. - Late decisionmaking keeps developers open to change. - It also helps to ensure that decisions are made only when the maximum amount of information is available. - Because of all of the above, late decisions reduce uncertainty and risk as well as eliminating waste.
How does the Iterative approach support the Lean core principle of delivering value?
The Iterative approach ensures regular delivery of value to the customer. It also allows the team to incorporate customer feedback into the development lifecycle and to respond rapidly to changes in customer requirements.
What is the Queuing Theory, and how does it apply to Agile software development?
According to the mathematical Queuing Theory, work processes are most efficient when small batches of work move through a system at a steady rate. This applies to the small, frequent iterations used in Lean and other Agile software development methodologies.
Describe "team empowerment" in the context of Lean.
A Lean principle that is common to all other Agile approaches is team empowerment. In the context of Lean, team empowerment means the following:
1. All team members - not just team leaders - are responsible for learning and applying Lean principles. 2. All team members should also have equal access to required resources. 3. All team members should participate in monitoring progress. 4. All team members should have the authority to implement decisions that will improve the end product.
Describe "amplifying learning" in the context of Lean
A Lean principle that is common to all other Agile approaches is amplifying learning. In the context of Lean, this means the following:
- ongoing feedback between team members - ongoing feedback between the team and the customer
What is Value Stream Mapping, and what is it used for?
Value Stream Mapping is used in Lean to assess work processes with the goal of identifying and eliminating waste.

Using a Kanban board helps ensure the following:
- that every member of the team has work to do and is not idle - that the status of tasks is transparent to the team and others - that workload does not exceed capacity at any point - that team members understand and focus on important aspects of the project
Which is Kanban?
a. a push system b. a pull system
b. a pull system.
Kanban is a "pull" system. Explain what this means.
Kanban is part of an approach in which the "pull" comes from the demand - that is, the supply or production is determined according to the actual demand of the customer.
This is in contrast to a "push" system, in which supply follows a forecast of demand. Because this is based on the anticipation of customer needs rather than actual, current customer needs, it can result in waste. Pushing work through a process also can create bottlenecks.
You are on a Scrum team that is using a Kanban board to track and communicate the team's progress. What is this combination called?
Scrum that incorporates Kanban is called Scrumban.

In Crystal teams, Osmotic Communication refers to what?
Osmotic Communication refers to communication that happens through the barrier of awareness. That is, team members in the same space unconsciously take in information from one another. In a shared environment, individuals are exposed to various sensory inputs even when they are not consciously aware of them. Osmotic Communication also lessens the need for information to be shared in more formal, time-consuming ways, such as meetings.
In the context of Crystal methodologies, what does Personal Safety refer to?
Personal Safety means that the level of trust within the team is such that any team member may express him or herself - for example, giving honest feedback or delivering bad news - in a positive, constructive way without fear of harsh reactions.
Personal Safety helps ensure that problems are openly discussed and addressed. This helps to resolve problems more quickly and efficiently and can boost productivity and morale.
In the context of Crystal methodologies, what is the opposite of Focus?
The opposite of Focus is multitasking. Multitasking and multiple projects waste time and effort. This is because switching focus requires a "settling in" period to become adjusted to the new task. Multiple projects also require other time-wasting activities such as meetings, phone calls, and creating status reports.
True or False: The Crystal methodologies provide a framework within which teams are able to work on multiple projects because it allows them to focus on single tasks for set periods of time.
False. The Crystal methodologies emphasize that teams work on only one project at a time, with tasks prioritized based on the needs of the project sponsor. The Crystal methodologies insist that interruptions be kept to a minimum.
Crystal emphasizes the need for rapid feedback on design decisions and issues of product quality. How does Crystal address this need?
To address the need for rapid feedback on design decisions and issues of product quality, Crystal promotes quick and easy access to subject matter experts. This also allows developers to get feedback about the results of each iteration.
True or False: The Crystal methodologies require that subject matter experts be co-located with the development team.
False. Subject matter experts do not need to be in the same office as the team, but they do need to be readily available by phone, e-mail, or other channels.

Dynamic Systems Development Method (DSDM) is unique in that it takes a business perspective instead of focusing on technical development. Its main focus is ensuring that the product that is developed fits the business purpose for which it is intended.
DSDM is based on what model?
DSDM is based on the Rapid Application Development (RAD) model.
True or False: Because it depends on continuous customer involvement, DSDM is typically used for open-ended projects without a tight deadline.
False. DSDM is typically used for projects with tight schedules and budgets.
True or False: DSDM is ideal for safety-critical projects.
False. Because it lacks a technical focus, DSDM is not recommended for safety-critical systems.
How does DSDM include integrated testing?
In DSDM, integrated testing begins very early and continues through the development lifecycle as a mandatory task for each software iteration. This helps to ensure that the system is robust and reliable and meets business needs.
How does DSDM use the 80/20 Rule?
DSDM follows the 80/20 Rule, which says that 80 percent of a system's business benefit comes from 20 percent of its functionality. With this in mind, the DSDM team prioritizes the critical 20 percent and works on this first so that maximum value is delivered to the customer sooner rather than later. After that, the remaining 80 percent is developed. This helps the project stay on schedule and within budget.
Explain Business Fit in the context of DSDM.
In DSDM, the main criterion for acceptance of final software is fitness for business purpose. This means that the software
- must address current business needs - have functionalities supporting critical business areas.
This is in contrast with how customers tend to focus on the final product: It must be complete and perfect, as planned from the project's beginning.
What are the sub-phases of the Project Lifecycle Phase in a DSDM project?
The sub-phases of the Project Lifecycle Phase in a DSDM project are the following:
1. Feasibility Study 2. Business Study
and these 3 iterative phases:
3. Functional Model Iteration 4. Design-and-Build Iteration 5. Implementation
What happens in the DSDM Pre-Project Phase?
In the DSDM Pre-Project Phase
- the project is identified and commissioned - the necessary funding is committed to the project
What happens in the DSDM Post-Project Phase?
The DSDM Post-Project Phase ensures that the product operates effectively and efficiently and includes all activities that take place after the software is delivered, including the following:
- maintenance - fixes - enhancements - upgrades
What happens in the Feasibility sub-phase in DSDM?
In the Feasibility sub-phase, you assess several aspects of the project:
- the likelihood that the project will meet the customer's business requirements - DSDM's suitability as a methodology for the project - Scope - Risks - Possible technical solutions to the customer's business problem - initial estimates of costs and timescales - quality tests that can be used to evaluate the product
What happens in the Business Study sub-phase in DSDM?
In the Business Study sub-phase, you hold workshops with the customer to
- gather business requirements - plan what to include in each Iteration - conduct prototype planning - gather system requirements - reviewing and updating project risk documentation - scoping nonfunctional requirements, such as security, performance, and usability
What happens in the Functional Model Iteration sub-phase in DSDM?
In the Functional Model Iteration sub-phase, you identify and design the product's functionalities. This involves the following:
1. converting the requirements from the Business Study phase into static models, such as visual, class, and data models 2. developers creating working-software prototypes of the Iteration's functionalities 3. working-software prototypes are tested and demonstrated to the customer to get feedback
What is the final result of the Functional Model Iteration sub-phase in DSDM?
The Functional Model Iteration sub-phase ends with a working prototype that includes all the functionalities identified during the Business Study stage. Nonessential functionalities that were left out of the prototype are discussed and listed so that they can be dealt with in the next sub-phase.
When does the Design and Build Iteration sub-phase happen in DSDM, and what takes place during this sub-phase?
The Design and Build Iteration sub-phase takes place at the same time as the Functional Model Iteration sub-phase. In the Design and Build Iteration sub-phase, developers
- create the actual functionality - integrate the functionality - test it in the overall system - the Functional Model as the plans and incorporates reusable aspects of the prototypes that have already been developed - write end-user documentation - addresses other nonfunctional requirements
What happens in the Implementation sub-phase in DSDM?
In the Implementation sub-phase, the team installs and tests the fully functional system in the customer's working environment and train users, operators, and support staff on how to use the system.
The team also assesses the impact of the software on business needs and discusses any additional requirements that the user would like developed in future Iterations.
If further iterations are needed, the team returns to the final 3 iterative sub-phases in the project's cycle.

Elements in the Should-Have category should be incorporated if possible. However, the project will succeed without them.
Elements in the Could-Have category of MoSCoW have what characteristic?
Elements in the Could-Have category are optional and don't affect business needs. They could be implemented as long as the time and effort they require won't have a negative impact on the essential aspects of the project.
Elements in the Would-Have category of MoSCoW have what characteristic?
Elements in the Would-Have category are optional and would be nice to include if there is spare time and funds left over after the final Iteration.
How does DSDM use Prototyping?
In DSDM, Prototyping involves making working models of software at regular intervals throughout the development process. The technique reveals difficulties that may arise later, enabling the team to make easier adjustments sooner rather than making difficult changes later when the system is in full development.
Prototyping also enables the team to demonstrate software to the customer, which helps in managing expectations and allowing the team to make changes based on the customer's feedback.
In the context of DSDM, what are Workshops?
Workshops are structured meetings in which various project stakeholders, such as developers and customers, gather to discuss project-related issues. This allows developers to seek clarity on requirements, and customers to suggest changes in requirements.
What is Visual Modeling?
Visual Modeling involves using diagrams and other visual representations to give customers an idea of how software will work. This helps to eliminate ambiguity and can help developers and the customer understand and confirm the business domain and what the system needs to do.

Story Point estimates are more accurate when arrived at collaboratively by the entire team. This is true for what 2 reasons?
Story Point estimates are more accurate when arrived at collaboratively because
- anyone potentially may be assigned any task, so the estimate should be based on input from everyone on the development team.
- everyone in the group can contribute different experiences and expertise.
True or False: Considering monetary cost is part of estimating the time and effort required to address each User Story in a project or iteration.
False. Agile teams do not estimate how much money will be spent developing each User Story. Estimating User Stories is meant to create a shared understanding of the relative size and complexity of each story.
In traditional project management, the focus is on estimating how long it will take to perform to complete the required work and identifying a date when it will be completed. In Agile, the focus is on what?
In Agile, the focus is on estimating the development effort that is required.
A Story Point represents what?
A Story Point represents a fixed amount of effort, for example 4 hours of 1 developer's time.
True or False: A Story Point is roughly equivalent to an hour.
False. Story Points should not be interpreted as equivalent to hours. The value of a Story Point can vary greatly from one team to the next.
True or False: A simple User Story identifying a relatively straightforward task will take less time to complete than one identifying a complex task or set of tasks.
False. A simple User Story, pointing to a task such as gathering website content, can take every bit as long as a complex Story pointing to a task such as configuring a database.
Story Points represent
a. an agreed-upon equivalent to a set number of hours it will take to complete a User Story b. the number of hours it will take 1 person to develop a User Story c. the relative size of each User Story in terms of the effort required to develop it d. 4 hours of 1 person's time
Story Points represent
c. the relative size of each User Story in terms of the effort required to develop it.
True or False: Story A has 1 Story Point. Story B has 5 Story Points. Therefore, it will take 5 times longer to complete Story B than it will to complete Story A.
False. Story points do not refer to the length of time it takes to develop a Story. Rather, they refer to the amount of effort.
True or False: Story A has 1 Story Point. Story B has 5 Story Points. Therefore, it will take 5 times the amount of effort to complete Story B than it will to complete Story A.
True. Story Points refer to the relative amount of effort it will take to develop User Stories.
Planning Poker is an adaptation of what technique?
Planning Poker is an adaptation of Wide-Band Delphi, in which members of a group estimate independently, compare and discuss individual results, and revise their estimates to arrive at a consensus.
When using Planning Poker to estimate larger stories, what size intervals should be used?
When using Planning Poker to estimate larger stories, you should use large intervals.
True or False: In Planning Poker, it is always useful to use small intervals when comparing the sizes of Stories.
False. It's useful to use small intervals only when comparing smaller stories. Larger stories should be compared using large intervals, so the values aren't too similar.
Planning Poker uses intervals based on what numerical series?
Planning Poker uses intervals based on the Fibonacci series.
Why use the Fibonacci series when estimating Story Points?
The Fibonacci series helps ensure appropriate intervals when comparing small or large User Stories.
What is a linear scale?
A linear scale, sometimes used for estimating Story Points, has the same interval between each number, such as 0, 1, 2, 3, 4, 5.
5, 10, 15, 20, 25 is an example of what kind of scale?
5, 10, 15, 20, 25 is an example of a linear scale, in which there is the same interval between each number. In this case, the interval is always 5.
1, 2, 4, 8, 16, 32 is an example of what kind of scale?
1, 2, 4, 8, 16, 32 is an example of a binary scale, in which each succeeding value is double the preceding value.
Name the 6 steps of Planning Poker, in order.
The 6 steps of Planning Poker are the following:
1. Choose a reference point. 2. Discuss the Story. 3. Estimate the Story individually. 4. Check for consensus. 5. Repeat 2-4. 6. Reach consensus.
A binary scale is particularly useful when estimating what type of User Story?
A binary scale is particularly useful when estimating larger User Stories because the high-end intervals are sufficiently large.
In Planning Poker, the Reference Point Story should be of what size?
In Planning Poker, the Reference Point Story should be average- or medium-sized, so the team estimates all other stories as larger or smaller.
What should you refrain from doing during Step 2 of Planning Poker?
Refrain from indicating which card you think you will choose during Step 2 of Planning Poker. You should be discussing the Story without openly estimating its size.
What happens during Step 3 of Planning Poker?
During Step 3 of Planning Poker, each team member chooses and raises a card indicating his or her estimate of a Story's size.
What does the Product Owner do during Planning Poker?
The Product Owner clarifies stories and answers questions; this person usually does not participate in estimating Story size.
What happens in Step 4 of Planning Poker?
In Step 4 of Planning Poker, the Product Owner and Team Leader check the cards for consensus.
What happens in Step 5 of Planning Poker?
Step 5 in Planning Poker happens when there is no consensus, in which case,
1. the participants with the highest and lowest estimates give a rationale for their estimates. 2. the team cycles through Steps 2-4 until they reach consensus.
What happens in Step 6 of Planning Poker?
In Step 6 of Planning Poker, the team has reached consensus on a Story's size. The Team Leader records the estimated size of the Story, and the team moves on to the next Story.
Ideally, the number of participants in Planning Poker should not exceed what number?
Ideally, the number of participants in Planning Poker should not exceed 10.
What can you do if the number of people participating in Planning Poker exceeds 10?
You can split participants into teams.
A team has estimated that it will take 10 Ideal Days to complete a particular User Story. What does this mean?
An Ideal Day involves the number of days it will take a single developer to build, test, and release the functionality described by a User Story under ideal circumstances and relative to the estimates of other User Stories in a project. Ideal Days don't take into consideration disruptions and multitasking.
What is the equation used to determine a team's velocity?
Velocity = Development Effort / Project Time
When is it most useful to rely on historical values to estimate a team's velocity?
Historical values are most useful when the team already has experience with the process, tools, product owner, and working together.
A team that has worked together in the past is now embarking on an entirely new and different project. How can they best estimate their velocity?
They can start with historical values as a rough estimate and then adjust this estimate after a few initial iterations.
When estimating a Release Plan using the velocity data from the first 2 or 3 Iterations of a project, it's generally a good idea to do what?
It's generally a good idea to estimate slightly upward because the team will improve its velocity over time.
The Product Owner uses velocity figures to make what two changes in the project?
The Product Owner uses velocity figures to
- Adjust the Release Plan - Increase or decrease the number of User Stories attempted in an Iteration
A project isn't due to start for several months, the resources aren't yet available, the team composition is new, and you aren't authorized to run a test iteration. How, then, should you estimate velocity?
In this case, you should use Forecasting.
When should you use Forecasting to estimate a team's velocity?
Use Forecasting when
- a project isn't due to start for several months - the resources aren't yet available - the team composition is new - you aren't authorized to run a test iteration
Forecasting involves what tasks?
1. Breaking User Stories down into tasks 2. Estimating the work effort involved in completing the tasks 3. Calculating the amount of work that can fit into an iteration 4. Determining the velocity required to produce the required work in the available time.
True or False: Forecasting involves a high amount of uncertainty.
True. Forecasting involves a high amount of uncertainty and should be used only when you do not have historical values or cannot run a test iteration.
You need to estimate the velocity for a team that has worked really well together on previous projects. What is the best approach for estimating this velocity?
For a team that already works well together, it's best to use historical data for the initial estimate. You can adjust this, if necessary after a few iterations.
What are some of the things that can reduce a team's velocity?
Some of the things that can reduce a team's velocity are
- burnout and overwork - changes in the team's structure - miscommunication - technological complexity - changes in the customer's requirements
How can burnout and overwork affect a team's velocity?
Tired people make mistakes that then need to be fixed, or, they may take longer to get work done.
How can changes in a team's structure affect a team's velocity?
People who have experience working together as a cohesive unit are generally more efficient. New members disrupt this.
High or unexpected technological complexity and needing to learn new tools or programming languages have what in common when it comes to a team's velocity?
All of these can reduce a team's velocity because the team is on a learning curve.
A Product Owner is unclear about requirements. How an this affect a team's velocity?
Unclear requirements lead to unnecessary rework.
What are the 6 factors that can determine the priority of User Stories?
The 6 factors that can determine the priority of User Stories are
Value-based prioritization in large projects may involve what?
Value-based prioritization in large projects may involve a detailed evaluation of the expected ROI of the product, taking into consideration
- the net present value of investments - the internal rate of return over time
Prioritization based on Cost involves what 2 considerations?
Prioritization based on Cost involves
- total cost of developing the functionality - the cost of supporting the functionality once it's developed
High-risk high-value stories should be given what priority?
High-risk high-value stories should be given high priority so they can be addressed early on.
What is market risk?
Market risk refers to how the market will respond to a product or features.
What is Releasability?
Releasability refers to the extent to which a deliverable can be released without requiring further development work or additional components.
Using the MoSCoW method of prioritization, in which category should you assign critical functionalities?
Critical functionalities should be assigned to the Must Have category.
Features that are not critical but are of high value to the customer, and that can be addressed with short-term work-arounds if needed should be assigned what category using the MoSCoW method?
These features should be assigned to the Should Have category. They have a fairly high priority.
Desirable features that will be included only if time and resources allow should be assigned what category using the MoSCoW method?
These features should be assigned to the Could Have category.
Features that would be nice to include but that aren't of high importance should be assigned what category using the MoSCoW method?
These features should be assigned to the Would Have category and given the lowest priority. They would be included in a later release or project.
When combining MoSCoW with Story Mapping, what Stories are the top level, or backbone of the map?
The Must Have Stories are at the top level of the story map.
A Story Map using the MoSCoW prioritization method shows what?
A Story Map using the MoSCoW prioritization method shows all the User Stories in a hierarchy and grouped by theme, or common functionality.
During later Iterations, it's best to mix what types of Stories?
During later Iterations, it's best to mix Must Have stories with lower priority stories. The lower priority stories create a buffer in case time runs out and something has to be dropped.
In later iterations especially, why is it inadvisable to have all top-priority stories?
If all stories are top-priority in an iteration, it becomes impossible to prioritize them.
What are the 4 main steps in Agile Release Planning?
The 4 main steps in Agile Release Planning are
1. Estimate User Stories 2. Estimate Velocity 3. Prioritize User Stories 4. Assign Stories to Iterations
Ideally a User Story should take what amount of time to develop?
Ideally a User Story should take 2-5 days to develop.
Ideally, how many User Stories should a team develop during an Iteration?
Ideally, a team should develop 4-10 Stories during an Iteration.
User Stories are developed during what phase of Release Planning?
User Stories are developed during the requirements-gathering phase of Release Planning.
Making User Stories too small results in what difficulty?
It can make the planning and development process too granular and complicated.
What is the appropriate guideline for combining too-small User Stories?
Combine small, related Stories that will take less than 2 days to develop.
Disaggregation refers to what?
Disaggregation refers to splitting User Stories into smaller ones.
Splitting User Stories into smaller ones is called what?
Splitting User Stories into smaller ones is called Disaggregation.
What are the different boundaries that can be used to split User Stories?
User Stories can be split by
- Data boundaries, that is, the types of data involved - Operation boundaries, that is, the operations that are performed as part of the Story - Cross-functional features that don't operate in isolation - Nonfunctional performance requirements - Sub-stories of mixed priority
The CRUD approach helps with using what type of boundary to split User Stories?
The Create/Read/Update/Delete approach helps with using Operation boundaries when splitting User Stories.
If an application behaves differently depending on a user's priviledges, this is an example of what kind of feature that can be used to split a User Story?
A team agrees to develop a set of features rather than to meet a fixed release date. The team uses developers' estimates and the features that the customer has requested as the basis for an estimation of a completion date. Which project planning approach is this?
This is the Feature-Driven project planning approach.
A team works with the customer to identify how many features, and how many story points, it can complete by a specified deadline. Which project planning approach is this?
This is the Date-Driven project planning approach.
As an Agile project manager, you must calculate approximately how many features the team can complete during an iteration. Within budget constraints you need to make sure the team is large enough to complete the project on time. Which project planning approach are you using?
You are using the Date-Driven project planning approach.
In Feature-Driven project planning, how is it best identify stories to be developed in an iteration?
It is best to group Stories by themes because they indicate a working product feature and releasability. It's also best to work on high-priority Stories in early iterations.
In the Kano method of prioritizing features, what does Must Have refer to?
Must Have features are
- basic - essential - expected
In the Kano method, what are Linear features?
Linear features are performance features. The more, or the better, the higher the customer satisfaction.
In the Kano method, what are Exciters?
Exciters are neither essential nor expected, so customers won't be disappointed if they're not included. Adding them, however, increases customer satisfaction.
In the Kano method, this type of feature never improves satisfaction, but leaving it out leads to customer dissatisfaction. What type of feature is this?
This is a Must-Have feature.
What is the minimum number of customers who should complete a Kano questionnaire?
At least 20-30 customers.
You ask how customers would feel if a particular model of car had a built-in movie screen for those in the back seat. What type of Kano questionnaire question is this?
What is a Kano Dysfunctional Question?
In a Dysfunctional Question, you ask how the customer would feel if a feature were left out.
In Kano, features that customers want and expect are called what?
In Kano, features that will increase customer satisfaction in direct relation to how well they are implemented are called what?
In Kano, features that aren't expected but will increase customer satisfaction if they are included are called what?
In Kano, features that aren't wanted and that will decrease customer satisfaction if they are included are called what?
In Kano, if it's not clear how including a feature will affect customer satisfaction, what type of feature is this?
In Kano, when customers don't care either way if a feature is included or left out, what type of feature is this?
In Kano, what types of Features should be given the top three levels of priority? And in what order?
1. Must Have 2. Linear 3. Exciter
When prioritizing User Stories, you can use a 2-by-2 Matrix. What is this tool?
It's a matrix for comparing two variables - such as importance and urgency, or risk and releasability - to one another.
If you wanted to compare features in terms of two variables - value and cost - what sort of matrix could you use?
You could use a 2-by-2 Matrix.
During the development process what should you do with features that pose high risk and high value?
You should focus on developing high-risk/high-value features first.
Why should you make high-risk/high-value features the top priority for development?
So that you will learn as early as possible whether you can get these features to work.
High-risk/high-value features should be what your team focuses on first. What type of features should you focus on second?
Low-risk/high value features should come second in priority.
You have used a 2-by-2 Matrix to identify high-risk/high-value features, and that's proven pretty handy. But how do you prioritize features in terms of Risk, Value and Cost?
You use two matrices: Cost-to-Value and Risk-to-Value. Use the first to identify your high priority features. Then plot those features in the second matrix.
Why is identifying and documenting all requirements at the beginning of an Agile project considered waste?
This is waste because
1. It's too soon for customers to know what they want at a detailed level. 2. Features identified later in the project could add significant value. 3. Extensive requirements documentation takes a great deal of time and effort to create and maintain. 4. Documenting requirements is an ineffective way to communicate.
What 4 situations necessitate more traditional project documentation in an Agile project?
More traditional documentation may be needed if
- stakeholders require it - regulatory agencies require it - the team is not co-located - it is needed for maintenance and updates
When regulations call for certain types of documentation, what should you do?
You should study the regulations and come up with a way to provide the needed documentation in the most efficient and least time-consuming way.
What 3 documents are created at the beginning of an Agile project?
The 3 documents created at the beginning of an Agile project:
What documents are created as an Agile project progresses?
The team creates Acceptance-Testing Documents as a project progresses.
What documents are created at or near the end of an Agile project?
At the end of the project, the team creates
- support documentation - end-user documentation
What does the Vision Statement define in an Agile project?
The Vision Statement defines the ultimate goal of a project.
In addition to a description of the ultimate goal of a project, what other information may be included in a Vision Statement document?
The Vision Statement document may include the following:
- financial and resource cost estimates - potential benefits and risks - scheduled milestones
What motivation should the Vision Statement provide?
The Vision Statement should
- motivate the sponsor and stakeholders to fund and support the project - motivate the team to achieve the project's goals
What information is contained in a Project Overview?
A Project Overview is a summary of critical information about a project. It contains the following information:
- the Vision Statement - technologies - operation processes - main customer contacts - important artifacts such as system models and source code
The Project Overview is particularly important for what members of the team? Why?
The Project Overview is particularly important for new team members because it tells them what they need to know to plan and prioritize their work.
What sort of information does Agile Requirements Documentation contain?
Requirements Documentation contains the following: - a summary of what the system should be able to do - relevant user stories - business rules - interface prototypes - new and refined/revised information as the project progresses
What is Acceptance-Testing documentation?
Every User Story requires Acceptance Criteria, which the team will use to test whether the requirement outlined in the Story has been met.
Support documentation might contain what information?
Support documentation might contain the following:
- problem-escalation procedures - a list of contacts - a trouble-shooting guide - help-desk training material
What are the 4 guidelines for Agile documentation?
Agile documentation must be
- valuable enough so that its benefits outweigh the costs of creating and maintaining it - focused - lean - necessary
What does it mean that Agile documentation should be focused?
Focused documentation means that
- each document has a single, clear purpose - no document's content overlaps with another document's content
As a general rule, when should Agile documents be created? Why?
Agile documentation should be created as late as possible, to avoid frequent updates and changes.
Who is the primary audience for the Project Overview?
The project team is the primary audience for the Project Overview.
What type of contract is typically used in a traditional project?
Traditional projects use fixed-price contracts.
Why is a fixed-price contract unsuitable for an Agile project?
Fixed-price contracts assume a fixed scope from the outset, thus preventing the team from identifying deliverables that add value as the project progresses.
Fixed-price contracts require that unambiguous monetary results indicate that a goal has been met. Why does this pose a problem for an Agile project?
Agile relies on customer and user feedback, which cannot be monetized.
Even if a business goal can be defined using monetary results, this is still problematic in an Agile project. Why is this?
Market forces and other factors outside of the team's control could still prevent the customer from achieving its business goals. Generally, a team should be held responsible only for the product it creates rather than ensuring particular business outcomes for the customer.
How do fixed-price contracts foster mistrust?
If either party tries to change requirements in a fixed-price contract, it often results in disputes over who will bear the cost of the change.
Conflicts caused by attempts to change requirements in a fixed-price contract violate what Agile principle?
This violates the Agile principle of valuing collaboration over contract negotiation.
List the Agile alternatives to a fixed-price contract.
Agile alternatives to fixed-price contracts are the following:
- Service with Series of Fixed-Price contracts - Cost-Reimbursable, also known as Time-and-Materials contracts - Not to Exceed with Fixed-Fee contracts - Incentive contracts
From a customer perspective, Agile projects are broken down into what two phases?
Initiation and Development.
What is the objective of the Initiation Phase of an Agile project?
The objective of the Initiation Phase is for the team to learn the customer's business and for the customer to learn about the technology that could be used for the product. The objective is not to deliver any product, not even requirements specification.
What sort of contract could you use for the Initiation Phase of an Agile project? Why?
Because the objective of the Initiation Phase is learning, which could be classified as consulting services. So, a general consulting service contract could cover this phase.
What is the objective of the Development Phase of an Agile project.
The objective of the Development Phase is to deliver increments of the product.
What sort of contract could you use during the Development phase of an Agile project?
You could draw up a series of fixed-price contracts for the deliverable of each Iteration.
Describe the Service with Series of Fixed-Price contract approach in an Agile project.
This approach uses the following contracts:
1. Initiation Phase: Service contract for consulting 2. Series of fixed-price contracts for the deliverable of each Iteration
What are the 2 main advantages of a Service with Series of Fixed-Price contract approach in an Agile project.
The 2 main advantages of a Service with Series of Fixed-Price contract approach in an Agile project are
1. The team is able to identify new features that can add value and cancel features that will not add value. 2. It is easier to apply a price to a small increment of the deliverable.
What is the Fixed Range variant of a Service with Series of Fixed-Price contract?
The Fixed Range sets a limit on the amount of time a team will work on a project, thus, the number of hours for which the customer will be billed - for example the contract may arrange for the customer to be billed for no more than 150-200 hours per month.
What is the Fixed Price Per User Story variant of a Service with Series of Fixed-Price contract?
The Fixed Price Per User Story variant includes an agreement that the customer will pay a Fixed Price Per User Story.
The Fixed Price Per User Story variant to a contract can provide what kind of incentive?
The Fixed Price Per User Story variant can provide an incentive to the team to complete as many User Stories as possible.
What is a Cost-Reimbursable, or Time-and-Materials contract?
With a Cost-Reimbursable, or Time-and-Materials contract, payment is based on the following:
- the amount of time developers work - the resources they use to develop the product
When a customer requests changes to what is being developed under a Cost-Reimbursable, or Time-and-Materials contract, what is understood to take place?
The customer will pay for any additional time and resources required to make these changes.
Why is a Cost-Reimbursable, or Time-and-Materials contract ideal for Agile projects?
These contracts allow for the flexibility that's needed when requirements change.
Who bears most of the risk in a Cost-Reimbursable, or Time-and-Materials contract? Why?
The customer bears most of the risk because even if developers don't finish the work, they are still paid for the work they have done.
For a Cost-Reimbursable, or Time-and-Materials contract to work, the customer needs to have a lot of what?
The customer needs to have a lot of trust in the development team.
For a Cost-Reimbursable, or Time-and-Materials contract to work, the team needs to be committed to what?
The team needs to be committed to doing the work efficiently, not dragging it out to collect extra pay.
What is an NTE/FF?
A Not-to-Exceed Fixed Fee contract.
What is a Not-to-Exceed Fixed Fee contract?
An NTE/FF contract contains the following:
- Fixed-fee base, or a set amount that the customer agrees to pay over and above the cost of developing the product - Not-to-Exceed condition, which sets the maximum amount that the customer will pay for the project.
True or False: An NTE/FF contract protects the customer more than it does the development team.
False. A Not-to-Exceed Fixed Fee contract protects both the customer and the developers.
What is the Fixed-Fee base in an NTE/FF project?
The Fixed-Fee base sets the amount that the customer agrees to pay over and above the cost of developing the product.
An NTE/FF contract protects the development team from what?
An NTE/FF contract protects the development team from losses it would otherwise incur if
- it finishes the required work much faster than estimated - the customer reduces the scope of a project by removing requirements
What is a Not-to-Exceed condition in an NTE/FF contract.
A Not-to-Exceed condition sets the maximum amount that the customer will pay for the project.
What is a Not-to-Exceed condition in an NTE/FF contract protects the customer from what?
A Not-to-Exceed condition in an NTE/FF contract protects the customer from paying more than what is considered a reasonable price even if project work is completed much more slowly than expected or other factors drive up development costs.
What is an Incentive contract?
An Incentive contract motivates development teams by offering rewards for good performance.
What are the 4 main types of Incentive contracts?
The 4 main types of Incentive contracts are
- Fixed-Price With Incentive - Cost-Reimbursable With Award Fee - Percentage Increase or Decrease Based on Time - Fixed Price Per User Story With Additional Hourly Rate
What is a Fixed-Price With Incentive contract?
In a Fixed-Price With Incentive contract, both parties identify performance targets in metrics, such as cost, schedule, or technical performance. Developers are offered financial incentive for exceeding the target metrics. When all work is done, the final contract price is determined based on the developers' performance in the metrics. The contract also establishes an upper limit for costs, with developers held responsible for any costs beyond this limit while still being obligated to finish the work.
A Fixed-Price With Incentive contract ensures that the customer and the development team share what?
A Fixed-Price With Incentive contract ensures that the customer and the development team share the risk when costs are within range.
With a Fixed-Price With Incentive contract, who bears the risk if costs are higher than the agreed-upon limit?
The developers bear the risk.
What is a Cost-Reimbursable With Award Fee Incentive contract?
With a Cost-Reimbursable With Award Fee Incentive contract, the team is reimbursed for its development costs and paid a fee for its performance, which is measured in terms of performance criteria agreed upon at the outset.
What is a Percentage Increase or Decrease Based on Time Incentive contract?
Percentage Increase or Decrease Based on Time Incentive contract ties payment to the developers' ability to meet the project deadline. For example, if the team finishes a month early, the customer pays a fixed fee plus a bonus. If the team finishes late, the customer pays a fixed fee minus a penalty.
What is a Fixed Price Per User Story With Additional Hourly Rate Incentive contract?
With a Fixed Price Per User Story With Additional Hourly Rate Incentive contract, the customer pays a fixed price per User Story plus an additional hourly rate that is lower than the usual rate.
A Fixed Price Per User Story With Additional Hourly Rate Incentive contract protects the customer from what?
A Fixed Price Per User Story With Additional Hourly Rate Incentive contract protects the customer from paying an excessive amount if the team is slow to accomplish its work.
With a Fixed Price Per User Story With Additional Hourly Rate Incentive contract, how is the team paid if its work is progressing more slowly than expected?
The team will still receive the fixed fee agreed upon at the beginning of the project as well as an hourly fee at a reduced rate. This compensates the team for the extra time spent on the work.
A contract for an Agile project should contain what information?
A contract for an Agile project should contain the following: - terms of payment - when the customer will be available to answer questions - the turnaround time the customer agrees to for acceptance testing - dates when new releases will be sent to the customer
What is the goal of risk management in an Agile context?
Risk management in Agile is preventing risks from jeopardizing the delivery of value to the customer.
What are the 5 categories of risk management in Agile?
How is risk management planning handled in traditional projects?
The project manager works with management and stakeholders to decide how risk will be managed for a project. The PM then incorporates the results of the discussions into a formal risk-management plan.
In Agile, who determines how best to handle risk?
All members of the project team, along with the Product Owner, who represents the customer, work together to determine how best to handle risk.
What are the two main methods of handling risk in an Agile project?
The two main methods of handling risk are
- Overt Method: Clearly identify risk as risk - Organic Method: Risks emerge as obstacles, assumptions, or concerns during planning and review sessions
How are risks documented in an Agile project?
- aren't documented at all - are documented informally, for instance, on a whiteboard
How does risk identification occur in a traditional project?
In a traditional project, risks are identified mainly at the outset, during initiation and planning. The project manager meets with a subset of team members and stakeholders and uses assumption-analysis, checklists, and other information-gathering techniques to identify risks. They record these risks in a Project Risk Register.
If risks are being identified overtly in an Agile project, what activities occur?
The team will allocate time in its regular meetings to identify and prioritize risks.
If risks are being identified organically in an Agile project, what activities occur?
Team members identify and discuss risks when updating one another on their projects.
The Agile approach to risk management upholds what Agile principle?
It upholds the principle of communication and transparency over formal documentation.
How is risk-response planning done in traditional projects?
The project manager and/or other team members plan how to respond to each identified risk:
- by avoiding it - by transferring it to another party - by mitigating its effects - by accepting it and establishing contingency resources
The team then develops a formal risk-management plan. This is mostly done at the beginning of a project, with some additional planning done at each phase.
In an Agile approach, risk-response planning involves what?
In an Agile approach, risk-response planning involves
In the context of risk management, what are Tolerances?
Tolerances are the upper and lower limits within which it's acceptable for various project-performance metrics to fall. Metrics include budget spending, iteration velocity, and customer-satisfaction ratings.
What is an Exception Plan?
An Exception Plans identifies what the team will do if any project metrics fall outside Tolerances.
When does an Agile team develop and agree on an Exception Plan? Why?
Before project work begins. This is preferable because emotions and stress may run too high once things start to go wrong.
What information should an Exception Plan include?
An Exception Plan includes:
- the circumstances that count as an exception and that would trigger the plan - possible causes of the circumstance - a review of tolerance limits to check if they are unrealistic or need updating - a list of possible solutions for resolving the problem - the recommended solution - a request for high-ranking stakeholders to decide on the solution
What does Quantitative Risk Analysis involve?
Quantitative Risk Analysis involves quantifying risks and their potential impacts, using concrete values, for example calculating monetary costs that would be incurred.
What does Qualitative Risk Analysis involve?
Qualitative Risk Analysis uses past experience, intuition, and judgement to determine risks and potential losses.
How is quantitative and qualitative risk analysis handled in traditional project management.
The project manager estimates the possibility and probability of risks occurring and then ranks them, using a scoring sheet, which identifies which risks need immediate response and which should simply be monitored.
True or False: In Agile, both Quantitative and Qualitative Risk Analysis are used in equal measure.
False. Agile generally relies on Qualitative Risk Analysis.
How is Risk Analysis documented in Agile?
The team keeps a prioritized list of risks in a highly visible place such as a whiteboard- an information radiator - to remind the team of the dangers.
How is risk monitoring done in traditional projects?
The project manager uses a Risk Register to record risks, their status, and planned responses. These are reevaluated during formal risk-management review meetings. In these meetings, the team uses risk audits, variance- and trend-analysis, and other methods of evalulation.

In traditional project management, what is used to measure a project's performance in terms of costs and schedule?
Earned Value Management (EVM) is used to measure a project's performance in terms of costs and schedule.
In an Agile context, EVM can provide what information?
Earned Value Management (EVM) can
- show how close a team is to meeting initial expectations - enable the team to forecast the impact that changes will have - give early warnings of below-expected performance levels, thus aiding in risk management - enables the team to track performance trends across the life of a project
EVM can help answer what questions from stakeholders?
Earned Value Management (EVM) can help answer
- how much to spend and when? - monetary value of actual work completed? - money spent so far? - how much do we plan to spend by the end of the project? - what is the estimated cost at completion?
What are the 3 variables used by EVM?
Earned Value Management (EVM) uses the following 3 variables:
- Budget at Completion (BAC) - Planned Value (PV) - Earned Value (EV)
What is Budget at Completion (BAC)?
Budget at Completion (BAC) is the total budget allocated to a project.
What is Planned Value (PV)?
Planned Value (PV) is the value of completed work at a given time.
How is Planned Value (PV) calculated?
PV is calculated by the planned percentage of work completed multiplied by BAC.
When using EVM, how do you calculate the percentage of work completed?
When using Earned Value Management (EVM), you calculate the percentage of work completed by dividing the current week number by the total weeks scheduled for a project. Multiply the result by 100 to get a percentage.
What is Earned Value (EV)?
Earned Value (EV) is the value of the work actually completed at the time of measurement.
How is Earned Value (EV) calculated?
Earned Value (EV) is calculated as the actual percentage of work completed multiplied by the project's BAC.
When using EVM, what is Actual Cost (AC)?
Actual Cost (AC) is the actual cost incurred up to a given point in a project.
When using EVM, what is Cost Variance (CV)?
Cost Variance (CV) is the difference between what a project has earned to date and what it has cost to date.
When using EVM, what is Schedule Variance (SV)?
Schedule Variance (SV) occurs when a project has deviated from its planned schedule. It is the difference between what a project has actually earned by a specified date and what it should have earned based on the planned schedule and budget.
When using EVM, what is Cost Performance Index (CPI)?
Cost Performance Index (CPI) shows how a project is really performing in terms of cost.
When using EVM, what is Schedule Performance Index (SPI)?
Schedule Performance Index (SPI) compares the value of performed work to the value of planned work.
How is Actual Cost (AC) calculated?
AC is calculated by adding up all project spending incurred to date.
What does the term Variance refer to?
Variance refers to any discrepancy between planned and actual performance.
Using EVM, you can calculate what variance?
Using EVM, you can determine variance in terms of both a project's cost (CV) and schedule (SV).
How do you formulate Cost Variance (CV)?
The formula for calculating CV is EV minus AC.
What does a negative CV value indicate?
A negative CV value indicates that a project has earned less than has been spent.
What does a positive CV value indicate?
A positive CV value indicates that the project has already earned a profit - less than a dollar has been spent for every dollar earned.
How is SV calculated?
The formula for calculating Schedule Variance (SV) is Earned Value (EV) minus Planned Value (PV).
What does a positive SV value indicate?
A positive SV value indicates that a project is ahead of schedule.
What does a negative SV value indicate?
A negative SV value indicates that a project has earned less than planned and so is behind schedule.
How do you calculate CPI?
To calculate Cost Performance Index (CPI), divide Earned Value (EV) by Actual Cost (AC).
What does a CPI value higher than 1 indicate?
A CPI value higher than 1 indicates that a project is earning more than is being spent.
What does a CPI value lower than 1 indicate?
A CPI value lower than 1 indicates a cost overrun. That is, a project is earning less than is being spent.
A CPI of 0.56 indicates what?
A CPI of 0.56 indicates that the project is earning only 56 cents for every dollar spent. This is a cost overrun.
How do you calculate SPI?
To calculate Schedule Performance Index (SPI), divide EV by PV.
An SPI greater than 1 indicates what?
An SPI greater than 1 indicates that a project is ahead of its planned schedule.
An SPI less than 1 indicates what?
An SPI less than 1 indicates poor performance: The project is behind schedule.
An SPI of 0.28 indicates what?
An SPI of 0.28 indicates that a project is progressing at only 28 percent of the pace originally planned.
In an Agile project, how do you calculate Actual Cost?
AC is calculated by the number of development hours multiplied by the hourly rate.
How do you calculate Budget at Completion?
To calculate BAC, multiply the ideal number of hours by the hourly rate. This represents the total labor costs if the project is completed according to plan.
When using EVM in an Agile project, what do you use as your unit of measure for a Project Period?
Instead of measuring the project period in weeks, use Iterations as the unit of measure. This, of course, assumes that all your iterations are of the same length.
When using EVM in an Agile project, how could you calculate Percentage Complete?
To calculate Percentage Complete, divide the number of Story Points completed divided by the total number of Story Points to be developed. Then convert this to a percentage.
When using EVM in an Agile project, how can you calculate Actual Cost?
Instead of measuring AC in money, you can measure it in terms of development time. So, AC is the number of hours or days it has actually taken to develop the story points that are now completed. This includes developers' overtime work.

Clarity, Frequency, Medium.
What are the 5 levels of the Agile "Onion" of Planning?
What 3 elements should a Project Charter for an Agile project contain?
Mission, Vision Statement, Success Criteria
What does an Agile Project Roadmap contain?
A Project Roadmap shows the Product Themes organized into a timeline.
What is a Theme?
A Theme is a large Feature or collection of related Features or User Stories.
What is the PMBOK definition of a Project Charter?
A Project Charter is "a document issued by the project initiator or sponsor that formally authorizes the existence of a project and provides the project manager with the authority to apply organizational resources to project activities."
What 6 things should an Agile Project Manager be mindful of at the beginning of a project?
An Agile Project Manager should
- meet with the Product Owner in advance to come up with a game plan - be prepared with necessary materials - clearly explain the process and objectives to the team - set an appropriate iteration timebox for the team - capture notes on discussions taking place - ensure the team is progressing rather than getting bogged down in too many details up front
What does the Product Roadmap do in regard to the Product Vision?
It provides a high-level view, coupled with a timeline, of the approach that the team will take to deliver the value identified in the Product Vision.
How Themes help with planning?
A Theme is a collection of User Stories grouped around a common functionality. Grouping Stories into Themes helps to identify different parts of a product so that these parts can be prioritized in the order in which they should be built.
What is a Plan of Record and what role does it play in Agile planning?
A Plan of Record is a document of overall intentions developed at the very beginning of an undertaking. In Agile, this is not a commitment; it is just a plan.
How does a User Role differ from a Persona?
A User Role defines what the user is doing when working with the software; it is a more general role such as "logged-in user" or "admin." A Persona is more specific, such as "first-year student" or "professor."
When defining User Roles, what questions should you ask?
When defining User Roles, ask the following questions:
- What is this type of user doing when they are working with the software? - What is the person's business priorities and how does the software fit with these? - How does the user interact with the software? - In what setting, environment, with what delivery system? - What other behaviors or needs does this user have?
As an Agile Project Manager, what should you be mindful of when introducing the Team to User Roles?
- clearly explain user roles, their benefits, and what the team's goals are - have some user roles identified beforehand - timebox the session - use 3x5 cards or a white board so can be collaborative - work with team to group, name, and prioritize user roles
What are some User Roles common to software products?
Common user roles are
- new user - existing user - admin user - super user - service - nontechnical user
How does identifying User Roles and Personals help in the Agile process?
They aid when writing User Stories.

The Product Owner is primarily responsible for keeping the Product Backlog updated and prioritized.
True or False: The Product Owner can add or remove items from the Product Backlog at any time.
True. The Product Owner can modify the Product Backlog at any time. The Iteration Backlog, however, is locked down once an Iteration begins, and only the Scrum Master can modify it if it becomes necessary to do so.
"As a sysadmin, I need to set up the development environment infrastructure." What kind of Story is this?
Foundational Story. Or Environment Story.
What is a Foundational Story?
This is a story to describe nonfunctional technical work that needs to be done to deliver value, such as setting up testing suite, or putting LDAP in place.
User Stories grouped together around a common functionality are called what?
A Theme. Or a Feature.
What does every User Story need in order to address its definition of "done"?
Acceptance Criteria. Or Validation Criteria.
What two subsets does every Story need?
- Tasks - Acceptance Criteria
What do Tasks refer to in a User Story?
These are the items of work that must be completed in order to address the Story.
What is Acceptance Criteria?
Acceptance Criteria are the criteria that must be met before a User Story is considered fully addressed. Criteria can include end-user validation, customer validation, unit/integrated testing, code reviews...
What are some examples of work that can be itemized using Foundational Stories?
Foundational Stories can be used for
- technologies that need to be in place before other work can start - dependencies from external teams - creative elements - spikes - defects - maintenance - training
Developers on the team take 3 days to bring themselves up to speed with Ruby On Rails. This is an example of what?
A Spike. Or a Business Capability Story.
When working with the team to develop User Stories, what 5 things should you, as the Agile Project Leader or Scrum Master, do?
- meet with the Project Owner beforehand to document all predetermined stories - discuss predetermined stories with the team - provide each team member with post-its and sharpies - explain the process and objectives to the team - ensure that the team does not get bogged down in details - timebox the session - capture any useful details that come up in the session for later discussion
What are some examples of Story Smells?
Mike Cohn's "Catalog of Story Smells" include
- stories that are too small - stories that are too big - interdependent stories - goldplating - too much detail - interface detail too soon - thinking too far ahead - lack of Project Owner and customer participation in writing and prioritizing stories
Why is it important to size Stories appropriately?
So that the work to address a Story can be accomplished within a single Iteration.
What are some of the prioritization themes to keep in mind when managing the Product Backlog?
Keep in mind the following prioritization themes:
- ROI or other financial value - business value - cost of developing and supporting - significance of proving new technology - high-risk features
User Stories are listed as the Y-axis in a table that has Customer Value, Annual Revenue, Story Points, etc. across the top as the X-axis. This is an example of what?
A User Story Decision Matrix, which helps in prioritizing Stories.
What is a main problem with User Story Decision Matrices?
They're easily manipulated, or fudged.
What is the Fire Alarm model?
The Fire Alarm model of prioritizing work is driven by Urgent + Important. It is a terrible model to use.
What are the 4 quadrants of Covey's Matrix?
These 4 quadrants are
Q1: Urgent and Important (Fire Fighting) Q2: Not Urgent but Important (Where You Should Be Working!) Q3: Urgent but Not Important (Unproductive Interruptions) Q4: Not Urgent and Not Important (Waste)
Of the 4 quadrants of Covey's Matrix, which is the most important? Why?
Q2: Not Urgent but Important. If we do the right things to create quality products, we will not fall prey to waste and interruptions, and we will not need to fight fires.
What is the Pareto Rule?
This is the 80/20 Rule: Most of the results in any situation are determined by a small number of causes.
What is a Risk-Adjusted Product Backlog?
This is a Product Backlog that is prioritized based on three primary factors: value, risk (uncertainty), and dependencies. It's called a Risk-Adjusted Product Backlog because it includes known and assessed risks.
A Product Backlog should be prioritized based on what 3 primary factors?
Value, Risk, and Dependencies.
What is a MMF?
Minimum Marketable Feature.
What is a Minimum Marketable Feature?
A Minimum Marketable Feature (MMF) is the smallest possible set of functionality that, by itself, has value. A Release containing just one of these Features would deliver value.
What should you, as an Agile Project Manager, do if a project has more than one Product Owner, each with his/her own Product Backlog?
Combine and prioritize those backlogs.
True or False: A Story Point = 4 hours of 1 person's time.
False. Story Points are not tied to hours in any way.
What is Relative Estimating?
Relative Estimating is used to estimate the size of User Stories: Which is the smallest Story? Which is the largest? Which ones fall in the middle?
True or False: When using Relative Estimating, it's best to compare the smallest Story to the Largest.
False. You should triangulate: Identify the smallest, largest, and medium-sized stories, and then use these to help estimate the size of the rest of the stories.
Time-based estimating focuses on elapsed time. Relative estimating focuses on what?
Relative estimating focuses on size and complexity in relation to other known factors.
When estimating the size of User Stories, what is Triangulation?
Triangulation is comparing an unknown to 2 or more knowns in order to determine its value. In the case of User Stories, you would compare a Story to two other Stories whose size has already been estimated.
When estimating the size of User Stories, what is Bracketing?
Bracketing is using ever tighter ranges of values to arrive at a proper comparison. With User Stories, you would compare a Story to one that has been identified as large and one that is small to see where it falls between those two in terms of size.
Why Story Points?
- help drive cross-functional behavior because the entire team can take part in estimating - story point estimates do not decay - story points are a pure (estimate by analogy) measure of size - estimating story points takes less time than hourly estimations
When determining Story Points, what is Affinity Estimating?
Affinity Estimating is grouping Stories of a similar size and estimating points.
What is Wideband Delphi?
Wideband Delphi is an estimating game similar to Planning Poker.
What are some different types of Story Point estimating?
Some different types of Story Point estimating are
Roman Pitchler's Agile Product Management With Scrum lists what 5 necessary attributes of a Product Owner?

True or False: Conflict is a team issue.
True. Conflict involves the entire team.
True or False: When dealing with conflict it is important to focus on the past, not the present.
False. When dealing with conflict it is important to focus on the present, not the past.
What 4 factors influence how project managers handle conflict?
The following 4 factors can influence how project managers handle conflict:
1. Relative importance and intensity of the conflict 2. Time pressure for resolving the conflict 3. The position taken by the players involved 4. The motivation to resolve conflict for the long-term or short-term

Agile teams use Continuous Planning, or Progressive Elaboration, in the top three levels of planning:
True or False: Progressive Elaboration is used in Iteration Planning.
False. Once an Iteration is planned, it should be locked in. Changes to an Iteration should be avoided if at all possible.
Developing the Project Charter, Roadmap, and Release Plan are done in what Iteration?

What, typically, is the time horizon for an Agile Roadmap?
The time horizon for an Agile Roadmap is typically 6-9 months.
Tasks to address a User Story are usually what size?
Tasks to address a User Story are usually sized so that they can be completed in 1 day.
What can be described as a thin slice of functionality that can be comprised of UI changes, middleware changes, or infrastructure changes?
A User Story.
According to the PMI-ACP Study Guide, what are the 4 types of non-user stories?
The 4 types of non-user stories are
- Foundational (or Technical) - Spikes (Analysis Stories) - Constraints (Global Acceptance Criteria) - Dependencies (Reliance on Others in the Organization)
According to the PMI-ACP Study Guide, how are Constraints documented?
Constraints are not put in the Product Backlog but are put on a separate board for all the team to see.
According to the PMI-ACP Study Guide, are Constraints considered "done" at some point?
Constraints are considered "done" only when the project is done.
According to the PMI-ACP Study Guide, this type of Story is about reliance on others in the organization.
According to the PMI-ACP Study Guide, this type of Story is used learn something or find out something.
This kind of story is called a Spike.
According to the PMI-ACP Study Guide, what is the ideal size of a Story?
Small enough to be completed in an Iteration but large enough to deliver value.
According to the PMI-ACP Study Guide, what is used to gather the detail behind User Stories?
What is Agile Modeling?
Agile modeling is used to discover the details behind User Stories and identify tasks to address those stories.
According to the PMI-ACP Study Guide, what 4 methods are used to gather detail for upcoming User Stories?
Wireframes, Mockups, Process Maps, Use Cases.
A research story is called a _____________.
A research story is called a Spike, or Analysis Story.
According to the PMI-ACP Study Guide, what are the 2 ways that Agile teams account for risk?
Agile teams account for risk by
- early identification of risks - short iterations focusing on smaller problems, which are inherently less risky
What 3 things can make it difficult (or impossible) to estimate the size of a user story?
These 3 things can make it difficult or impossible to estimate the size of a user story:
- The story is too large (needs to be sliced into smaller stories) - Insufficient information (the Product Owner needs to provide more details) - Lack of domain knowledge (the team has had no experience building what is being requested)
True or False: acceptance criteria are the same as acceptance tests.
False. Acceptance Criteria are not the same as acceptance tests.
Name as many User Story "Smells" as you can.
Mike Cohn's User Story Smells:
- too small - too big - interdependent - goldplating - too much detail - includes interface detail - thinking too far ahead - lack of customer participation in writing and prioritizing
What is Goldplating?
Adding "value" that no one has asked for or wants.
Why is it important to size User Stories correctly?
A User Story needs to be right-sized so that it can be addressed within a single Iteration.
Name 5 considerations to keep in mind when prioritizing User Stories in the Product Backlog.
When prioritizing User Stories, keep in mind
- its financial value of a story (ROI, etc.) - its business value - the cost of developing and supporting the functionality - the significance of proving new technology - high risk features
True or False: Financial value usually is a sole factor in prioritizing a Feature or User Story.
False. Financial value (ROI, etc.) is usually not a sole determining factor when prioritizing a Feature or User Story.
In this table, User Stories are listed as row headers. Relevant priority considerations, such as Revenue, Risk, Story Points (Effort), are listed as column headers. Values are then filled in, such as 20 Story Points, or an Annual Revenue of $1 million. What is this table? What is it used for?
This is a Decision Matrix. It is used for prioritizing User Stories.
In the context of User Stories, what is a Decision Matrix, and what is it used for?
Decision Matrix is used for prioritizing User Stories by identifying their Size (Effort), Risk, Business Value, Financial Value, etc.
True or False: A Decision Matrix is an objective weighing of the value and risk of User Stories.
False. A Decision Matrix looks objective, but it is actually a subjective value multiplied by a subjective weighting. It also can easily be manipulated and fudged.
True or False: It is better and more accurate to have a large group of individuals contributing to a User Story Decision Matrix.
False. The larger the group, the more difficult it is to manage the Decision Matrix.
What is a Kano Analysis?
Kano is used to prioritize Features or User Stories. Its classifications are
- Must Have - Satisfier (or Linear) - Delighter (or Exciter) - Dissatisfier (or Indifferent)
True or False: You will never build a Dissatisfier (or Indifferent) into a system.
False. It's usually inevitable that some Dissatisfiers, or Indifferents, will be built into a system. An example is compliance to some regulation - the user cares not a whit for this addition, yet it is necessary.
In Kano Analysis, what classification gets top priority?
In Kano Analysis, what classification gets second-to-top priority?
Satisfier, or Linear.
Why should Story Point size estimating never be time-based?
Estimating the time to address a User Story in hours immediately looks like a promise and a deadline, and the customer will hold you to it.
What is Ideal Time?
Ideal time is estimated time assuming no distractions. It is not estimating as if nothing will go wrong.
True or False: Ideal time is estimated time assuming no distractions and nothing going wrong.
False. Ideal time is estimated time assuming no distractions. It is not estimating as if nothing will go wrong.
How do customers, stakeholders, marketers, administration, and others react to our estimates?
They form expectations.
When we consider customers, stakeholders, marketers, and others, what is the advantage of Relative Estimating?
Relative Estimating doesn't have time, or a "deadline" associated with it; therefore, these individuals will be less likely to form expectations about "when can I get this."
Relative Estimating is based on what two characteristics of a User Story?
Size and Complexity.
What are the problems with time estimating?
Problems with time-based estimating:
- Forms expectations - Too many variables
When estimating the size of User Stories, how does Bracketing differ from Triangulation?
Triangulation is comparing a Story of unknown size to 2 or more Stories of known size in order to determine its size. Bracketing is determining the two extremes - largest Story and smallest Story, and then using those to help determine the sizes of Stories falling between those extremes.
When estimating User Stories, what is Bracketing?
Bracketing is determining the two extremes - largest Story and smallest Story, and then using those to help determine the sizes of Stories falling between those extremes.
You are doing a "sanity check" after having estimated relative sizes of a group of User Stories. What does this "sanity check" involve?
During the "sanity check", you ask mathematical questions, such as "Story A is 1 point. Story B is 4 points. Is Story B really 4 times larger than Story A?"
You are doing a "sanity check" after having estimated relative sizes of a group of User Stories. What is the benefit of this "sanity check"?
The "sanity check" helps to ensure that your estimates are consistent. During the sanity check, you ask mathematical questions, such as "Story A is 1 point. Story B is 4 points. Is Story B really 4 times larger than Story A?"
Your team groups Stories that appear to be of similar size and then assigns the same points to Stories within these groups. What is this exercise called?
How many User Stories in the Product Backlog should you estimate at one time?
You should estimate enough to fill a Minimal-Marketable Feature (MMF), or if that is not possible, enough to fill a minimum of 3 Iterations.
What is a Baseline Story in Planning Poker?
A Baseline Story is a small story to use as a baseline of 2.
What are Anchor Stories in Planning Poker?
Anchor Stories at sizes 5 and 13, along with a Baseline Story of 2, help with Triangulation.
What are the 2 main advantages of Planning Poker?
Everyone gets an equal voice, and it drives discussion and collaboration.
In a round of Planning Poker, the team is stuck between 2 adjacent numbers. What should you do?
Establish a rule that when the team is stuck between 2 adjacent numbers, you pick the larger number and move on.
True or False: The Product Owner should be present at Planning Poker.
True. The Product Owner needs to be present to explain requirements.
Unless you all come up with the same number the first time around in a Planning Poker hand, what should you do?
You should always estimate twice, with a discussion between estimates - the discussion should especially focus on the highest and lowest estimates.
After playing 4 hands of Planning Poker your team still hasn't reached a consensus on a User Story. What's probably going on?
Your team doesn't have enough information about the User Story and needs to get further details from the Product Owner and/or Subject Matter Expert. Or a Spike (Analysis Story) may be needed.
How much time per Story should you spend in Planning Poker?
What components of a Story can be especially helpful during Planning Poker?
The Acceptance Criteria.
During Planning Poker, the team realizes some additional work needs to be done, or some different Features are necessary, even. What should you do?
Write these up as User Stories for later prioritization in the Backlog.
True or False: When estimating size, User Stories should examined independent of one another.
False. User Stories should be estimated by comparing them to one another.
True or False: Velocity is a good short-term predictor.
False. Velocity is a good long-term predictor but not a good short-term predictor.
A Story is partially completed at the end of an Iteration. How many of its Story Points should be considered completed?
Zero, unless the remaining work can be broken out into a new User Story.
Velocity is a measure of team _____________.
Velocity is a measure of team throughput; that is, how many Story Points of work the team can finish in 1 Iteration.
What are some factors that can affect team velocity?
Factors that can affect team velocity are
- resource issues - interruptions - multitasking (both on work within the Iteration and work spread across multiple projects) - support issues
If all is going as it should, what will happen to your team's velocity over time?
It should normalize.
How many Sprints will it take before you can determine your team's velocity?
This depends on the team and other factors. But 4-6 rolling sprints should do it.
Your team has just completed 5 rolling Sprints. What can you now do to determine your team's velocity?
Take the number of User Stories completed in each Sprint and figure the average. The average is your team's velocity and can be used for planning how many Stories to commit to in the next Sprint.
Stakeholders and Product Owners need to understand what about Velocity?
Velocity is not always consistent or predictable.
When estimating velocity for your team's first Iteration, what type of Stories should you consider first?
Consider 1 or 2 relatively large and difficult Stories first. Can they be accomplished in this Iteration with time to spare? If so, add more stories. If not, remove 1 of them, or start with smaller Stories.
What are the 6 steps of Release Planning?
The 6 steps of Release Planning:
1. Determine available project time 2. Determine Iteration length 3. Break down Features into User Stories 4. Estimate User Stories 5. Prioritize User Stories 6. Select Stories for Iterations and Release dates
In a Feature-Based Release Plan, what is locked and what is estimated?
In a Feature-Based Release Plan, the Scope is locked and the Schedule is estimated.
In a Schedule-Based Release Plan, what is locked and what is estimated?
In a Schedule-Based Release Plan, the Schedule is locked and the Scope is estimated.
True or False: It is usually best to start with Feature-Based Release Planning.
False. It is usually best to start with a Schedule-Based Release Plan: Fix the Target Date, not the Features.
If the Stories that need to be delivered hinge on regulatory compliance, what sort of Release Plan should you use?
You should use a Feature-Based Release Plan: Lock the Scope, estimate the Schedule.
Release Plans serve as what?
What is a Hardening Sprint?
A Hardening Sprint, or Integration Iteration, is a time for integrating between systems and doing any User-Acceptance Testing that was not addressed in previous Sprints.
What is preferable to relying on an Integration Iteration, or Hardening Sprint?
In addition to the priority of User Stories, what else should the team be mindful of during Release Planning?
Dependencies, Constraints, Critical Path, Themes.
What role does Velocity play in Release Planning?
Velocity indicates how many Story Points your team can address, on average, during an Iteration - so it helps you plan ahead what and how many Stories to be completed in each Iteration.
Why is Release Planning important?
- connects the Project Roadmap to Iterations and team Velocity - results in the Release Plan, an important Information Radiator
How does the Release Plan relate to the Product Vision and Roadmap?
An important Information Radiator, the Release Plan
- provides visibility into how the team will deliver the value identified in the Product Vision - shows how the Roadmap unfolds into working Iterations with predicted team Velocity
What is another name for a Story Review?
A Story Review is also called StoryTime, or Product Backlog Grooming.
What happens during a Story Review?
The Product Owner and the rest of the team groom the Product Backlog and prepare Stories for upcoming Iterations.
What kinds of documentation and materials are useful during a Story Review, or Product Backlog Grooming session?
The following documents are useful during this session:
Designers and Coders work together to develop a Rapid Prototype, or a working prototype of a feature or system.
Why is a Story Review so important?
It is important because
- the Product Backlog needs to be continually revisited, reprioritized, and groomed - Stories need to be developed for upcoming Iterations
What are the 4 steps of Iteration Planning?
The 4 steps of Iteration Planning:
1. Drill down into each Story by priority. 2. Identify specific tasks to address each Story. 3. Estimate each Task in Ideal Hours. 4. Compare the Task's Ideal Hours to the Capacity of the individual(s) who will work on that Task. 4. Commit as a team to deliver the Iteration's work.
Velocity is used in what way during Iteration Planning?
Velocity is used to decide how many Stories the team can commit to in the upcoming Iteration.
What is Capacity?
Capacity is how many hours of work each individual on the team can take on during an Iteration. Team Capacity is how many hours the team as a whole can take on during an Iteration.
As a rule, a Task should take how much time to complete?
A Task should take less than 1 day's work.
True or False: It's acceptable if a Task requires more than 8 hours' work.
True. If multiple team members can work on the task and complete it within 1 day, then this is acceptable.
Breaking Stories down into Tasks that require less than 1 days' worth of work enables the team to identify what?
During Iteration Planning, the team realizes that one Story it was planning to address in the upcoming Iteration is larger than the original estimate of 3 Story Points. According to Mike Cohn, what should the team do?
The team should not re-estimate the Story unless
- the original estimate is wildly inaccurate - relative size has dramatically changed; for example, another story to which this one was compared is significantly larger or smaller
In these cases, it's actually better to create a new Story rather than re-estimate the old one.
Studies have shown that in an 8-hour work day, an individual has _________ hours of productive time.
What is the Paperclip Exercise?
In the Paperclip Exercise,
1. The ScrumMaster distributes to each team member 1 paperclip per hour that that individual is available in the upcoming Iteration. Clips are color-coded per each person. 2. When an individual commits to a Task, he or she gives up 1 clip for each ideal hour the Task requires. 3. Once a person's clips are gone, no more clips!
What is a Story's Definition of Done?
Definition of Done for a Story is when
- all Tasks are done - all Validation Criteria are met
What is an Iteration's Definition of Done?
Definition of Done for an Iteration is when all work that the team has agreed upon and committed to is complete, for example:
- all code is written - all code is integrated - all code is unit/integration tested - all configuration is complete - all documentation is written - all acceptance criteria met - all severity-1 and -2 defects are closed
What needs to be complete and ready before Iteration Planning can begin?
Before Iteration Planning can begin,
- the Product Backlog must be prioritized - the Release Plan must be up to date and on hand - the Product Owner must be prepared to discuss Story details - all tools needed for the Iteration must be in place - the team must agree on the Iteraion's Definition of Done - the team must be aware of the planned Cadence (length of Iterations)
Who should NOT be present during Iteration Planning?
Executives and Stakeholders other than the Product Owner.
Who should be present during Iteration Planning?
The entire team, including Scrum Master and Product Owner.
During Iteration Planning, what's the recommended way to document Tasks?
Draft Tasks on a white board or their own cards first. Then transfer them to the Story cards.
True or False: During Iteration Planning it's best to assign hours to Tasks as you identify them.
False. It's best to identify all Tasks first, so that the team has an full understanding of all the work that needs to be done. Then assign ideal hours to each Task.
During Iteration Planning, what should be done regarding individuals working on multiple projects (shared resources)?
Regarding shared resources:
- Make sure to have an accurate idea of the time each individual is able to commit to the project at hand, and do not overcommit the person. - Be mindful that an individual working on multiple projects is multitasking, which will further reduce his or her productivity.
True or False: When a person takes ownership of a Task during an Iteration, it means that he or she will complete all of the Task's work.
False. Taking ownership means the person will see the Task through to completion; it does not mean the person must do all the work.
The Daily StandUp, or Daily Scrum, is an example of what Agile mechanism?
Inspect and Adapt.
During the Daily Scrum, who should identify when a conversation should be taken offline?
The Scrum Master.
After the Daily Scrum is finished, and offline conversations start, what should the Scrum Master do?
Release those who do not need to be part of the offline conversations.
During the Daily StandUp, each person should talk for about how long?
What happens during an Iteration Review?
During the Iteration Review, the team
- reviews completion of work - moves stories if necessary - splits stories if necessary - agrees, as a team, what was Done
What can be used as a checklist to make sure that a Story has been fully addressed during an Iteration?
The Definition of Done for that Story.
Stories unfinished during an Iteration should be ______________________.
Returned to the Product Backlog to be reexamined.
Stories that are partially finished at the end of an Iteration count as how any Story Points completed?
Unfinished Stories count as Zero.
If you do choose to carry unfinished Stories over into the next Iteration, what should you do with their Story Points?
Keep them at full value; do not subtract points. This is so that once the story is finished, the team gets full points at that time.
What should happen at the Demo?
The Demo is for demonstrating working software completed during the Iteration.
What should not be shown in the Demo?
Do not show the following in the Demo:
- unfinished work - work that the customer will not readily recognize as value (code, system configurations, Spikes, nonfunctional requirements that were met, etc.)
Why are Demos a good thing?
- give the team an opportunity to showcase its work - build trust with the customer and stakeholders - clearly demonstrate the team's progress - provide an opportunity to get feedback and identify new requirements
True or False: Each Iteration should include a Demo.
True. Each Iteration should conclude with a Demo showing the customer completed work.
Without a Demo at the end of each Iteration, what could happen?
Without Demos, the team could end up wasting weeks and months of work building something the customer does not want. This is because the team is not getting the following:
- regular customer buy-in - regular feedback on whether the team is on the right track
What is the difference between Capacity and Velocity?
Capacity is the number of hours the team is able to work on Tasks during an Iteration. Velocity is the average number (calculated over time) of Story Points a team can complete in an Iteration.
What is a Task Board?
A Task Board is an Information Radiator showing the team's progress on completing Tasks during an Iteration.
What is the sole purpose of a Task Board?
To communicate to everyone the status of Stories and/or Tasks during an Iteration.
True or False: A Scrum of Scrum happens daily.
False. A Scrum of Scrums happens as often as needed, which could be 2 or 3 times a week.
True or False: Each team's Scrum Master attends the Scrum of Scrums.

A Burn Down chart that shows a spike upward on Day 3 of an Iteration indicates what?
This indicates that more work was added to the Iteration Backlog on Day 3.
This document shows the amount of work planned versus the amount of work actually completed. What is it?
A Burn Up Chart.
This chart shows the number of Iterations in a Release on the X axis and Total Planned Story Points for the Project on the Y axis. Lines show Planned Points for each Iteration, Completed Points for each Iteration. What type of chart is this?
A Release Burn Up Chart.
This document shows the number of days in an Iteration on the X axis and the number of Story Points committed to on the Y axis. One line starting at 0 in the lower left corner shows the ideal progress. Another line starting at the same point shows actual progress. What is this document?
An Iteration Burn Up Chart
What does a Cumulative Features Diagram show?
A Cumulative Features Diagram shows, using colored areas:
- Total Features - Features in Progress - Completed Features
This document shows the top 10 project risks and their calculated risk exposure. It tracks this risk exposure over the project's Iterations. What is this document?
A Risk Burn Down Chart.
How do you calculate risk exposure?
risk exposure = probability of risk (percent) * size of loss (days)
What does a CvC metric show?
A Complete vs. Commit (CvC) metric is a simple bar chart showing the number of Story Points a team has committed to vs. the number of Story Points completed.
This document shows the number of defects carried over into ensuing Iterations. What is this document?
An Escaped Defects Chart.
A CvC chart shows that a team consistently delivers about 5 more Story Points than they commit to. What is this team doing?
This team is
1. under-promising and over-delivering (sand bagging) 2. working on Stories outside of their planned Iterations
What baseline data is needed in AgileEVM?
In AgileEVM, the following baseline data is needed:
- number of planned sprints per release - length, in days, of each sprint - number of story points planned per release - budget planned for a release - start date of the project
What ongoing data is needed in AgileEVM?
In AgileEVM, the following ongoing data is needed:
- number of sprints completed - net story points added (can be negative) - cumulative story points completed
Schedule Performance Index is a measure of what?
Schedule Performance Index (SPI) is a measure of a project's performance and efficiency.
Cost Performance Index is a measure of what?
Cost Performance Index (CPI) is a measure of a project's budget, or cost, efficiency.
A Cost Performance Index of greater than or equal to 1 indicates what?
A Cost Performance Index of greater than or equal to 1 indicates that the project's actual costs are on track with what was planned.
A Cost Performance Index of less than 1 indicates what?
A Cost Performance Index of less than 1 indicates that the project's actual costs are greater than what was planned - a cost overrun.
In AgileEVM, what is Earned Value vs. Planned Value?
Earned Value vs. Planned Value is a team's actual performance vs. what was planned.
In AgileEVM, what is Planned Release Story Points?
Planned Release Story Points (PRSP) is the Story Points planned in each Release.
In AgileEVM, what is Expected Percentage Complete?
Expected Percentage Complete (EPC) = Current Sprint Number (e.g. Sprint Number 17) ÷ Total Planned Sprints
The Scrum process can best be described as
a. a methodology that takes good programming practices to the extreme b. an iterative process in which a product increment is built every 30 days c. an iterative process that results in incremental releases every 30 days d. an iterative process that focuses on feature-driven development
