What do you understand by Software Development Life Cycle (SDLC) phases?
Various software development approaches are defined and designed which are employed during development process of software, these are also referred as “Software Development Process Models” (Example- Waterfall model, incremental model, V-model, iterative model, RAD model, Agile model, Spiral model, Prototype model etc.). Each and every process model follows a particular life cycle in order to ensure success in process of software development.
The software life cycle models describes the phases of the software cycle and also the order in which those phases are executed. Each and every phase produces deliverables required by the next phase in the life cycle. These requirements are translated into design. Codes are produced according to the design which is known as development phase. After coding and development the testing verifies the deliverable of the implementation phase against requirements.
