a) What are the principal features of iterative and incremental process models such as the Unified Process (UP) that differentiate them from the Traditional Life Cycle (Waterfall) model? b) Explain how those differences allow projects to avoid difficulties, such as late-design breakage, that are often experienced by projects that use the Waterfall. c) Despite its limitations, the Waterfall may still be a good choice under certain circumstances. Outline those circumstances and give an example of the sort of project for which the Waterfall could be an acceptable process model. a) What are the principal features of iterative and incremental process models such as the Unified Process (UP) that differentiate them from the Traditional Life Cycle (Waterfall) model? b) Explain how those differences allow projects to avoid difficulties, such as late-design breakage, that are often experienced by projects that use the Waterfall. c) Despite its limitations, the Waterfall may still be a good choice under certain circumstances.
