THE SYSTEMS DEVELOPMENT LIFE
CYCLE (SDLC)
What exactly is the SDLC? - correct answer The systems development life cycle
(SDLC) is a conceptual model used in project management that describes the
stages involved in an information system development project, from an initial
feasibility study through maintenance of the completed application.
The SDLC is composed of four fundamental phases: - correct answer - Planning
- Analysis
- Design
- Implementation
Each of the _____include a set of ______, which rely on techniques that produce
specific document files that provide _____ about the project. - correct answer
phases, steps, understanding
To Understand the SDLC: - correct answer - Each phase consists of steps that
lead to specific deliverables.
- The system evolves through gradual refinement.
Phase I: Planning - correct answer - This phase is the fundamental process of
understanding why an information system should be built.
- The Planning phase will also determine how the project team will go about
building the information system.
- The Planning phase is composed of two planning steps.
, Two Planning Steps: - correct answer 1. During project initiation, the system's
business value to the organization is identified (How will it lower costs or
increase revenues?)
2. During project management, the project manager creates a work plan, staffs
the project, and puts techniques in place to help the project team control and
direct the project through the entire SDLC.
Phase II: Analysis - correct answer - The analysis phase answers the questions of
who will use the system, what the system will do, and where and when it will be
used.
- During this phase the project team investigates any current system(s), identifies
improvement opportunities, and develops a concept for the new system.
- This phase has three analysis steps.
Three Analysis Steps - correct answer - Analysis strategy
- Requirements gathering
- System proposal
Analysis strategy: - correct answer This is developed to guide the projects team's
efforts. This includes an analysis of the current system
Requirements gathering: - correct answer The analysis of this information leads
to the development of a concept for a new system. This concept is used to build a
set of analysis models.
System proposal: - correct answer System proposal: The proposal is presented
to the project sponsor and other key individuals who decide whether the project
should continue to move forward.
