Each process model follows a particular life cycle in order to ensure success in process of software development. Software life cycle models describe phases of the software cycle and the order in which those phases are executed. Each phase produces deliverables required by the next phase in the life cycle. Requirements are translated into design. Code is produced according to the design which is called development phase. After coding and development the testing verifies the deliverable of the implementation phase against requirements. There are following six phases in every Software development life cycle model: 1  Requirement gathering and analysis. 2  Design.
Phases of the software development life cycle (SDLC) are explained step-by-step, as are iteration concepts, in Robin Goldsmith's expert response to a tester's question.hases of the software development life cycle (SDLC) are explained step-by-step, as are iteration concepts, in Robin Goldsmith's expert response to a tester's question.
