This example models the refinement of (high-level) goals into more concrete goals, and the refinement of concrete goals into requirements or constraints that describe the properties that are needed to realize the goals. The refinement of goals into subgoals is modeled using the aggregation relationship. The refinement of goals into requirements is modeled using the realization relationship.
In addition, the principles may be modeled that guide the refinement of goals into requirements.
