Chapter 7. Capturing Concerns with Use Cases
Understanding stakeholders’ real concerns is critical to successful software development. Concerns come from various sources and can be about different aspects of the system. Use cases provide a single technique to describe what the system must do to address these concerns. We distinguish between two major categories of use cases: application and infrastructure use cases. Application use cases describe how users interact with the system to perform the desired functionality. Infrastructure use cases describe what the system does to add qualities such as usability, reliability, performance, and supportability to each step of an application use case.
