Traditional software life cycle models traditional models of software evolution have been with us since the earliest days of software engineering. They allow to develop more complete versions of the software. Scalability if the software process were not based on scientific and engineering concepts, it would be easier to recreate new software than to scale an existing one. The following phase starts after the previous phase has. Evolutionary model is a combination of iterative and incremental model of software development life cycle. Using these models the developer can develop increasingly more complete versions of the software. Generic process models the waterfall model separate stages of specification and development.
