SDLC

The stages of SDLC can be characterized and divided up in different ways, including the following:

· Project planning, feasibility study: Establishes a high-level view of the intended project and determines its goals.

· Systems analysis, requirements definition: Refines project goals into defined functions and operation of the intended application. Analyzes end-user information needs.

· Systems design: Describes desired features and operations in detail, including screen layouts, business rules, process diagrams, pseudocode and other documentation.

· Implementation: The real code is written here.

· Integration and testing: Brings all the pieces together into a special testing environment, then checks for errors, bugs and interoperability.

· Acceptance, installation, deployment: The final stage of initial development, where the software is put into production and runs actual business.

· Maintenance: What happens during the rest of the software's life: changes, correction, additions, moves to a different computing platform and more. This, the least glamorous and perhaps most important step of all, goes on seemingly forever.
