WATERFALL MODEL The waterfall model is a linear, sequential approach to the software development life cycle ( SDLC ) that is popular in  software engineering  and  product development . The waterfall model emphasizes  a logical  progression of steps. Similar to the direction water flows over the edge of a cliff, distinct endpoints or goals are set for each phase of development and cannot be revisited after completion. The term was first introduced in a paper published in 1970 by Dr. Winston W. Royce and continues to be used in applications of industrial design. The waterfall methodology is composed of seven non-overlapping stages : 1.     Requirements: Potential requirements, deadlines and guidelines for the project are analyzed and placed into a  functional specification . This stage handles the defining and planning of the project without mentioning specific processes. 2.     Analysis: The system specifications are analyzed to generate product models and  bu

It is also referred to as a  linear-sequential life cycle model . It is very simple to understand and use. In a waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases. The Waterfall model is the earliest SDLC approach that was used for software development. The waterfall Model illustrates the software development process in a linear sequential flow. This means that any
