Overview of SDLC

System Development Life Cycle (SDLC) sets out the steps to be performed when developing systems, the work to be done in each step and the deliverables to be produced. It applies to all types of system development projects. By following SDLC, it ensures planning the project at the beginning and monitoring it along the way so that the schedule is met and the final system meets the requirements.

SDLC comprises a number of consecutive phases:

1. Initial Request
2. Feasibility Study
3. External Design
4. Internal Design
5. Programming
6. System Test
7. Acceptance Test
8. Implementation
9. Post Implementation
