ORGANIZING USE CASES

A small system may be expressed as a half-dozen use cases that involve two or three actors. As you tackle larger systems, however, you must define structuring and organizing principles. Otherwise, you can sink under a profusion of use cases, some of which have in common major parts of the flows of events. This profusion may make the requirements hard to understand and can make activities such as planning, prioritizing, and estimating very difficult.

The first structuring concept is that of a use-case package, in which you group related use cases into one container. You can also exploit relationships among use cases. To achieve this, you must look closely at the flow of events.
