System Development Life Cycle (SDLC)

The Systems development life cycle (SDLC) is a conceptual model that is used in the project management which describes the stages involved in the information system development project, from an initial feasibility study through maintenance of the completed application. SDLC is used to correct problems in existing system, and to improve the system quality and structure. It certainly makes the process easy for building a system and helps to reduce failures such as unclear objectives, possibility of not meeting the user needs, or cost overruns. We can generally consider the SDLC in five phases. These 5 phases are repeated until the desired or efficient output is achieved. The 5 phases of system development life cycle are:
1. Planning
2. Analysis
3. Design
4. Implementation
5. Maintenance

1. Planning:
This phase begins when the project is defined and the appropriate resources have been selected. The first part of the planning phase involves collecting, defining and validating functional, support and training requirements. The second part involves developing initial life cycle management plans, including project planning, project management, Configuration Management, support,
