Check Items
Is it easy to understand what the system does by reviewing the model?
Does the Use-Case Survey 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?
Have all use cases been identified?
Do the use cases identified collectively account for all required behavior of the system? Have all features identified in the Vision document for this iteration 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?
Is the model consistent?
Is the system behavior consistent under the same conditions and with the same input?
Are all relationships between use cases 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?
Are use-case packages 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?
Do 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?
Are individual use cases properly specified?
Have you reviewed the quality of each use case specification using the Checklist: Use Case.
