Summary

In this chapter, we've elaborated on the concept of the use case, which serves as the workhorse for much of our requirements work. We've described the benefits of the use-case approach, outlined the basic elements of the use case, and defined a step-by-step approach to building the use-case model that serves as the primary requirements information repository for our project. In later chapters, we'll develop these concepts further, including a look at implementation and testing techniques that are use-case-driven .
