Evolutionary Model | Software Engineering

Evolutionary model is also referred to as the successive versions model and sometimes as the incremental model. In Evolutionary model, the software requirement is first broken down into several modules (or functional units) that can be incrementally constructed and delivered.


Iterative Waterfall Model | Software Engineering

In Iterative waterfall model, the feedback paths are provided from every phase to its preceding phase. In practice, it is not possible to strictly follow the classical waterfall model for software development work. In this context, we can view the iterative waterfall model as making necessary changes to the classical waterfall model so that it becomes applicable to practical software development projects.


Software Development Life Cycle (SDLC)

A software development life cycle (SDLC) is a series of identifiable stages that a software product undergoes during its lifetime. A software development life cycle model (also called process model) is a descriptive and diagrammatic representation of the software life cycle.
