Check Items
It is easy to understand what the system does by reviewing the model
Does the use-case model provide a clear, concise overview of the purpose and functionality of the system? Are there no long chains of include relationships, such as when an included use case includes other use cases? These can obscure comprehension. Are included use cases independent of the use cases that include them? If several use cases contain similar subflows, have you investigated whether factoring this common behavior into an included use case will simplify the model?
All use cases have been identified
Do the use cases identified collectively account for all required behavior of the system? Have all features identified in the vision document been addressed by at least one use case? Have all nonfunctional requirements that must be satisfied by a specific use case been captured in that use case? Have you verified that the use-case model contains no superfluous behavior (known as "gold-plating")? Is each concrete use case associated with at least one actor, as it should be? Is every actor associated with at least one use case?
The model is consistent
Is the system behavior consistent under the same conditions and with the same input?
All relationships between use cases are required
Does each included use case make the model easier to understand, implement, and maintain? Is each concrete use case (not an included use case) independent of other use cases?
Use-case packages are used appropriately
Have cross-package dependencies been reduced or eliminated to prevent model ownership conflicts Is packaging intuitive? Does the packaging make the model easier to understand and implement?
All model elements have appropriate names
Have you verified that no two use cases have the same name? Does each actor have a name that effectively describes that person's role?
Individual use cases are properly specified
Have you reviewed the quality of each use-case specification using the Checklist: Use Case?
