Four stages of SDLC
- 4 stages of the SDLC: Planning, Analysis, Design, Implementation
Stage 1-Planning? What happen?
- Planning: Determine why and how a system should be built. Approval of a
project is a function of two entities:
,- system request: summarize business needs, the value of a system that
support those needs.
- feasibility analysis: technical feasibility, economic feasibility, organizational
feasibility (will it be used?).
Approved projects enter project management, in which the project manager
creates work plan, staffs the projects, and put techniques in place to aid in
control.
Deliverable: project plan.
Stage 2-Analysis? What happen?
- Analysis: seeks to answer who use the system, what the system will do, and
where and when it will be used; investigates current system(s), identifies
improvement opportunities, and develop concepts for the new system.
- Analysis strategy: studies the as-is system and envisions designs of the to-
be system
- Requirements gathering: develop system concept based on analysis of
gathered info. The system concept is then used to develop a set of business
analysis models - that describe how the business will operate. The models
typical represent data and processes needed to support the business.
- System proposal: analysis + system concept + models -> system proposal to
be evaluated by project sponsor and approval committee.
Stage 3-Design? What happen?
- Design: Determine how exactly the system will operate in terms of hardware,
software, and network infrastructure; user interfaces, forms, and reports used;
specific programs, databases, files needed.
- Determine design strategy: system developed by company's programmers?
Outsourced? Buy existing package?
- Develop basic architecture and interface design
, - Develop database and file specifications
- Develop program design: defines what programs to write and what each will
do
Stage 4-Implementation. What happen?
- Implementation: the system is built or purchased.
- System construction: system is built and tested.
- System installation: turn off old system and turn on new system. Training
plan is crucial: teach users how to use the system and manage changes
caused by the new system.
- Support plan: post-implementation reviews, ways to determine changes
needed for the system.
Definition of Business Needs
Business need is the reason for the project to be initiated.
Definition of Business requirements

need to have.
Definition of Business Value
Business value: tangible and intangible values brought about by the system,
often determined by the project sponsor.
