Use Cases

This page provides a review of the Use Case sites on the web. We provide an introductory discussion of Use Cases, including their purpose, applications, and techniques for their construction. In addition, we provide links to some of the best web sites for learning about Use cases, including the sites with the most instructive examples, and those teaching advanced concepts that might not be apparent from a quick search of the web.

Overview

Use Cases are a modeling aid used in software design to describe a sequence of events in a way that both the end users of a system, and the system designers and developers, can each understand completely. Use cases typically describe an event initiated by either a human user or another application, however the event and response are usually external, to maintain separation of responsibility between the designer and the user. The users should not have to be concerned about thread synchronization, for example, and the users should not need to care how the feature will be implemented. By communicating in a common language, end users may indicate what they require from the system, and designers may understand how those externaly visible requirements from the users translate into derived requirements internal to the system, in modules and subsystems not necessarily visible to the users.
