Is the included use case a required behavior?

Is the included use case a required behavior?

• A. Yes
• B. No
• C. Optional
• D. Irrelevant

Answer: (A)

In use-case modeling, an included use case represents behavior that is always invoked as part of the base use case. It’s a mandatory piece of the overall flow, factored out to be reused across scenarios. Because the base use case is designed to include that behavior every time it runs, the included use case is required when the base use case executes. If you need behavior that may or may not happen, you’d model it with an extend relationship or alternative flows, not with include. So the right interpretation is that the included use case is a required behavior.
