Functional Domain

The Functional Domain Viewpoints addresses information needs during the System Requirements definition Process. It focuses on conceptual black box aspects of the system.

E.g. it translates Operational Domain (intended solution) usage into the notion of System Functions defining the demanded system behavior and quality attributes - performance, safety, security, etc.; the demanded system behavior as it is perceived by the User or other Entities at the System Boundary (known as usage behavior). The result of the Functional Domain viewpoint-oriented elaboration approach is a comprehensive System Specification.
