There are different versions of the systems development life cycle. Here I'm presenting a US version of the model. The SDLC phase concept is used to describe functional systems development activity, to gain control of the complexities of systems development, and to ensure the needs of customers and users are the basis for technical activity. The SDLC process is best described as a series of phases occurring in various degrees and stages of overlap. The diagram below shows the seven major phases of systems development tailored to the U.S. House of Reps environment and the overlap that may occur during execution.
There are many variations which you can learn from the following website.
In general, a typical SDLC can be divided into the following phases:
- Project planning, feasibility study: Establishes a high-level view of the intended project and determines its goals.
o Here one needs to determine if a project warrants the investment. The phase should identify the customer, user, mandate, and basic operating concept. This phase should provide a preliminary investigation of alternatives and risk analysis, and a high level cost-benefit analysis to determine if the project has a favorable return on investment. The project information should show the expected cost increase or decrease and the capabilities or benefits gained, and is critical to the project approval process. The program ...
