System Development Life Cycle (SDLC)
the overall process for developing information systems, from planning and analysis through implementation and maintenance.
What are the phases that comprise SDLC?
The Planning Phase
establishes a high-level plan for the intended project and determines project goals.
The Analysis Phase
the firm analyzes its end-user business requirements and refines project goals into defined functions and operations of the intended system.
the specific business requests the system must meet to be successful.
establishes descriptions of the desired features and operations of the system including screen layouts, business rules, process diagrams, pseudo code and other documentation.
takes all the detailed design documents from the design phase and transforms them into the actual system.
brings all the project pieces together into a special testing environment to eliminate errors and bugs, an verify that the system meets all the business requirements defined in the analysis phase.
when the organization places the system into production so users can begin to perform actual business operations with it.
the organization performs changes, corrections, additions, and upgrades to ensure the system continues to meet its business goals.
a set of policies, procedures, standards, processes, practices, tools, techniques and tasks that people apply to technical and management challenges.
a sequence of phases in which the output of each phase is the input for the next phase.
-Oldest and best known.
consists of a series of tiny projects.
aims for customer satisfaction through early and continuous delivery of useful software components developed by an iterative process using the bare minimum requirements.
What are the primary forms of Agile Methodology?
Rapid Application Development Methodology
-A.K.A. Rapid Prototyping
Extreme Programming Methodology
Rational Unified Process(RUP) Methodology
Rapid Application Development(RAD) Methodology
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
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.
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.
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.
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.
What does the SMART criteria do?
it gives useful reminders about how to ensure that the project has created understandable and measurable objectives.
What are the parts to the SMART criteria?
a formal, apporoved document that manages and controls project execution.
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.
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.
