A use case is a collector for scenarios that describe an actor interacting with a system in pursuit of a goal. The workshop starts from this definition, showing how use cases can be written, cross-connected and managed. You will work with others around you, attempting to list use cases for a system, write a main scenario, and uncover failure scenarios in an impossibly short time frame. Expect to encounter differences in writing styles and to discover that use cases are much trickier to write than they seem. Learn the degrees of variation that still permit use cases to be effective.
