True or False: There is a hard and fast distinction between scenarios and use cases — they are fundamentally different techniques with no overlap.

Correct Answer

False

Explanation

There is no hard and fast distinction between scenarios and use cases. Some people consider each use case to be a single scenario; others encapsulate a set of scenarios in a single use case, where each scenario is a single thread through the use case. They can be used in either way in practice.
