Which of the following would be considered the oldest and most well-known software development method?

A. Spiral

B. Clean room

C. Waterfall

D. Prototyping

Solution

C. The waterfall method is the oldest and one of the most well-known methods for developing software systems. It was developed in the 1970s and is divided into phases. Each phase contains a list of activities that must be performed before the next phase can begin. Answer A is incorrect because the spiral model is a combination of the waterfall and prototyping methods. Answer B is incorrect because the clean room software development method focuses on ways to prevention defects rather than ways to remove them. Answer D is incorrect because prototyping was developed in the 1980s to overcome weaknesses in the waterfall method. It is a four-step process: develop an initial concept, design and implement an initial prototype, refine the prototype until it is acceptable, and then complete and release the final version of the software.
