Patterns for Effective Use Cases

Structure: The Use Case

CompleteSingleGoal	Write each use case to address one complete and well-defined goal. That goal may be at any level in the EveryUnfoldingStory.
VerbPhraseName	Name the use case with an active verb phrase that represents the goal of the primary actor.
ScenarioPlusFragments	Write the success story line as a simple scenario without any consideration for possible failures. Below it, place story fragments that show what alternatives may occur.
ExhaustiveAlternatives	Capture all alternatives and failures that must be handled in the use case.
Adornments	Create additional fields in the use case template that are outside the scenario text, to hold the supplementary information that is useful to associate with the use case.
