Checkpoints: Use-Case Realization

• The use-case realization completely realizes the selected sub-flows of the use case; there is no missing behavior.
• All additional requirements on the use case have been handled
• All required behavior has been unambiguously distributed among the model elements participating in the use-case realization.
• All exceptional cases to be considered in the current iteration have been handled.
• Behavior has been distributed to the correct model elements, taking into consideration the responsibilities of the model elements.
• Where several diagrams illustrate the use-case realization, the role of each is clear, and the diagrams are consistent with one another in their presentation of common behavior.
