IREB Certified Professional for Requirements Engineering – Foundation Level — Question 15

For an interview, you have prepared a use case diagram for the system to be specified. You decide to talk through a use case in detail with the stakeholder. You receive very useful feedback which must now be documented.
Which of the following means of expression is least suitable to document the details of a single use case?

Answer options

• A. State diagram
• B. Activity diagram
• C. Natural language
• D. Context diagram
• E. Class diagram

Correct answer: D

Explanation

The correct answer is D because a Context diagram provides a high-level view of the system's interactions with external entities, making it unsuitable for capturing the specifics of a single use case. In contrast, State diagrams, Activity diagrams, and Natural language are more detailed and can effectively convey the intricacies of a use case. Class diagrams are also not ideal for this purpose as they focus on the structure of the system rather than the behavior of a specific use case.
