Selection Criteria for Alternate Software Life Cycle Process Models. (FinalReport)

摘要

The importance of selecting an appropriate software life cycle process model forsoftware development projects is discussed. Software life cycle process models can be fit into a hierarchy at different levels of abstraction. The conventional, incremental and evolutionary process models are classified at the highest level of abstraction in this hierarchy. At the next level are the waterfall, hybrid prototyping, operational specification, and transformational process models. This hierarchy divided the selection of a process model into two steps. To support the selection of a process model for a project, a set of criteria and their values are defined. Under each criterion, the most appropriate process model is determined. These selections are partially verified by looking at a set of project case studies. An example of the use of the criteria for evaluating a project and then selecting a process model is given.
