A. Clear specification of the goals with the help of use cases and associated activity diagrams Use cases help operationalize goals by showing how users interact with the system to achieve something. Activity diagrams visualize the workflow and support refining abstract goals like “easy to operate” or “no distraction” into actionable system behavior. This is a recognized method in the IREB CPRE-FL syllabus for refining goals into functional requirements. ✅ C. Decomposition of the goals with the help of goal trees, in order to obtain more concrete goals Goal trees are explicitly recommended in the syllabus for breaking down high-level goals into sub-goals and concrete requirements. For example, “easy to operate” might decompose into measurable goals like “menu depth ≤ 3”, “response time < 1s”, etc.
