The Waterfall Model

The linear sequential process of software development described by Winston W. Royce in 1970 is popularly known as the Waterfall Model of Software Development. Also referred to as the classic life cycle, the linear sequential model presents a systematic approach that is based on progression from one stage to another namely requirement analysis, design, implementation, testing and finally support. Even after the adaptation of many new methodologies such as prototyping and agile, the classic approach presents a very strong case for scenarios where the requirements are fixed and generally helps in understanding the evolution of software engineering processes. The approach is very similar to one followed in many other engineering disciplines such as manufacturing and construction.
