What is a use case?

• A. Background information including organization size and specialty and current systems and hardware in place.
• B. A technique for documenting the potential requirements of a new system or any type of system change.
• C. The defined learning curve for users/ administrators.
• D. Both a and c

Answer: (B)

A use case is a technique for documenting the potential requirements of a new system or any type of system change. It focuses on how users or external systems interact with the system to achieve specific goals, outlining the steps, actors, triggers, and any alternate flows. This helps capture functional requirements from the user’s perspective and guides design and testing.

The other descriptions don’t fit a use case. Background information about organization size, specialty, and existing hardware is contextual project information, not the interaction model of the system. The defined learning curve pertains to usability and training needs, not how the system behaves in response to user actions. So the use case concept centers on capturing typical user-system interactions to specify what the system should do.
