Systems development life cycle

Model of the software development life cycle, highlighting the maintenance phase

In systems engineering, information systems and software engineering, the systems development life cycle (SDLC), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system.^[1] The SDLC concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both.^[2] There are usually six stages in this cycle: requirement analysis, design, development and testing, implementation, documentation, and evaluation.
