Capability Pattern: Identify System Goals and Requirements

The first step is to define top-level system goals that are then successively refined to requirements. These requirements can be annotated with formal constraints. Concurrently, obstacles and uncertainties can be identified and corresponding measures to mitigate them can be introduced into the requirements model. Finally, the requirements are validated with the stakeholders. The activity can be repeated and the requirements are thus successively refined. Apart from the requirements model, a system goal model capturing the high-level goals, a conceptual domain model capturing important concepts that come up, and a glossary explaining important terms are created.
