![]() ![]() That includes gathering requirements and documentation, system design, implementation, testing, delivery, and maintenance. Its structure is simple because every project must go through the same sequence of events. The waterfall model uses a clear and defined set of steps to follow when compared with other methodologies. List of the Advantages of the Waterfall Model Several waterfall model advantages and disadvantages are worth considering when there is a development approach to consider. A 1970 article by Winston Royce also receives credit for using this approach, although the term wasn’t used. A presentation by Herbert Benington during that series of meetings would get republished in 1983 to explain the concept. The first known use of the waterfall model occurred in 1956 at the Symposium on Advanced Programming Methods for Digital Computers. It creates a highly-structured physical environment where design changes would become prohibitively more expensive as the project moved further along. ![]() Progress typically flows downwards, like a waterfall, through the phases of conception, initiation, analysis, and more. This method is typically seen in the areas of construction development and engineering design because each step must get fulfilled before the next one can follow. Each set of circumstances depends on the deliverables that came from the previous step as it corresponds to a specialization of task-oriented approaches. The waterfall model breaks down project activities into linear sequential phases. ![]()
