When developing software, a prescriptive process model must be followed. When it comes to collaborative projects, however, the stages or works might be split among the participants. However, in individual projects, no work can be shared as a single member, but practical difficulties can be overcome by effectively managing process groups. As a result, rather than group projects, the prescriptive process model should be chosen. When choosing a viewpoint process model, there are a few things to keep in mind. The scope of the project’s validity, the impact of the process, and the level of confidence, all must be considered.
