rapid prototyping, emphasizes extensive used involvement in the rapid and evolutionary construction of working prototypes of a system, to accelerate the system development process.
is a smaller-scale representation or working model of the users' requirements or the proposed design for an information system.
Extreme Programming(XP) Methodology
breaks projects into four phases and the developers cannot continue into the next phase until the previous phase is complete.
Rational Unified Process (RUP) Methodology
provides a framework for breaking down the development of software into four gates each gate consisting of executable iterations of the software in development -owned by IBM
Gate one: Inception
This phase ensures all stakeholders have a shared understanding of the proposed system and what it will do.
Gate two: Elaboration
This phase expands on the agreed-upon details of the system, including the ability to provide an architecture to support and build it.
Gate three: Construction
This phase includes building and developing the product.
Gate four: Transition
Primary questions answered in this phase address ownership of the system and training of key personnel.
uses small teams to produce small pieces of software using a series of "sprints," or 30 day intervals, to achieve an appointed goal.
Project Management Institute (PMI)
develops procedures and concepts necessary to support the profession of project management.
a temporary activity a company undertakes to create a unique product, service or result.
the application of knowledge, skills, tools, and techniques to project activities to meet project requirements.
an individual who is an expert in project planning and management, defines and develops the project plan and tracks the plan to make sure it is finished on time and on budget.
any measurable, tangible, verifiable outcome, result or item that is produced to complete a project or a part of a project. EX. design doccuments, testing scripts.
represent key dates when a certain group of activities must be performed. EX. Completion of the planning phase is a milestone.
Project Management Office
an internal department that overseas all organizational projects.must formalize and professionalize project management expertise and leadership. primary initiative is to educate the organization on techniques and procedures necessary to run successful projects.
Describe the Triple Constraint.
It involves time, scope and cost. Basically these three variables are all directly linked to each other. When one of the variables changes, atleast one other is also affected. EX. If you move up a projects finish date, it will cost more money and it will also cause you to decrease the scope(eliminate details, features and functions) due to lack of time.
time, cost, scope
project management interdependent variables
individuals and organizations actively involved in the project or whose interests might be affected as a result of project execution or project completion.
the person or group who provides the financial resources for the project.
Focus on organizational goals, Categorize business priorities, Perform financial analysis
Project management roles
time, scope, resources, industry changes, communication, expectations, quality, costs, methodologies and tools, organizational changes, SDLC, technological changes
a document issued by the project initiator or sponsor that formally authorizes the start of a project and provides the project manager with the authority to apply some organizational resources to project activities.
Project Scope Statement
links the project to the organizations overall business goals.
quantifiable criteria that must be met for the project to be considered a success.
specific factors that can limit options.
are factors considered to be true, real, or certain without proof or demonstration. EX. hours in a work week or time of year the work will be completed.
a formal, apporoved document that manages and controls project execution.
it gives useful reminders about how to ensure that the project has created understandable and measurable objectives.
specific, Measurable, Agreed Upon, Realistic, Time Frame
What are the parts to the SMART criteria?
a trigger that enables a project manager to close the project before completion.
PERT(Program Evaluation and Review Technique) Chart
a graphical network model that depicts a projects tasks and the relationships between them.
a logical relationship that exists between the project tasks, or between a project task and a milestone.
estimates the shortest path through the project ensuring all critical tasks are completes from start to finish.
a simple bar chart that lists project tasks vertically against the projects time frame, listed horizontally.
Communication, People, Change
Managers focus on managing these areas for success
offers procedures and policies managers can use to help manage change during system development.
Change Management System
includes a collection of procedures to document a change request and identifies the expected impact associated with the change
Change Control Board (CCB)
is responsible for approving or rejecting all change requests.
In-sourcing (in-house Development)
uses the professional expertise within an organization to develop and maintain its information technology systems.
is an arrangement by which one organization provides a service or services for another organization that chooses not to perform them in-house.
Engaging another company within the same country for services.
contracting an outsourcing arrangement with a company in a nearby country. Often this country will share a border with the native country.
using organizations from developing countries to write code and develop systems. in offshore outsourcing the country is geographically far away.
The business problem
Any flaws in accurately defining and articulating the business problem in terms of what the business users actually require flow onward to the next phase.
The plan disadvantage
Managing costs, resources, and time constraints is difficult in the waterfall sequence.
The solution disadvantage
The waterfall methodology is problematic in that it assumes users can specify all business requirements in advance.
Fundamentals of RAD
Focus initially on creating a prototype that looks and acts like the desire system, Actively involve system users in the analysis, design, and development phases, Accelerate collecting the business requirements through an interactive and iterative construction approach
Onshore outsourcing model
direct customer control and close location
Nearshore outsourcing model
mid customer control and location
Offshore outsourcing model
Indirect customer control and remote location
why develop software
drive business operations and ensure work flows throughout a company
