What is the function of the "Derive Requirement" relationship?

The function of the "Derive Requirement" relationship is to outline requirements that originate from a higher-level need. This means that it establishes a connection between general, overarching needs or objectives and the specific requirements that are derived from them. In systems modeling and requirements engineering, establishing this relationship is crucial as it ensures that all derived requirements align with and support broader project goals. This connection helps in understanding how lower-level requirements fulfill the strategic vision or needs of stakeholders.

By focusing on deriving requirements, it facilitates traceability, ensuring that each requirement has a clear purpose and justification derived from the higher-level need. This ultimately aids in requirement management, prioritization, and validation, ensuring that the development process remains aligned with the intended outcomes and stakeholder expectations.
