Which of the following is FALSE for use case diagrams?
Which of the following is FALSE for use case diagrams?
Multiple Choice Options
- A
Use cases can be inserted anytime during requirements refinement
- B✓ Correct Option
Collaboration diagrams include activities within use cases
- C
Use cases represent actors
- D
Use cases can include exceptions
Detailed Technical Solution & Explanation
In UML, Collaboration diagrams (communication diagrams) show structural object interactions through message numbering, whereas Activity diagrams model workflows and sequential activities. Collaboration diagrams do not model internal activities of use cases; that is the distinct domain of Activity diagrams.
Option Analysis:
•
Option A (Use cases can be inserted anytime during requirements refinement): Incorrect statement. Use cases are continuously discovered and added across iterative requirements gathering.
•
Option B (Collaboration diagrams include activities within use cases): Correct (the statement is FALSE). Collaboration diagrams model message-passing between object instances, not functional activities.
•
Option C (Use cases represent actors): Incorrect statement. Use case models depict the relationship between actors and goals.
•
Option D (Use cases can include exceptions): Incorrect statement. Use cases routinely incorporate extension points and exception flows via «extend» relationships.
