Adoption of traditional software engineering

Waterfall model is to define the activities of software life cycle as several working stages connected in a fixed order, just like a waterfall, and finally get the software product.

1970, WinstonRoyce put forward the famous waterfall model, which was the only widely used software development model until the early 1980s. The software process of traditional software engineering methodology can basically be described by waterfall model.

The core idea of waterfall model is to simplify the process and separate the realization and design of functions, which is convenient for division of labor and cooperation, that is, to separate the logical realization from the physical realization by using structured analysis and design methods. The software life cycle is divided into six basic activities: planning, requirements analysis, software design, programming, software testing and operation and maintenance, which stipulate their fixed order from top to bottom and are interrelated, and fall down step by step like a waterfall.
