Phase B |
Phase C |
Phase D1 |
|
Ensure that the defined internal and external Interfaces to space segment, ground and other segments, and subsystems demonstrate a complete set of interfaces. Ensure that all interfaces are identified, requirements are defined, and are consistent with interface control documents.

| 2.2.4-6-2 Ensure all internal and external interfaces are identified and interactions understood |
Phase B |
Phase C |
|
Ensure applicable interface control documents detail compatibility of interfacing systems or components. Ensure all interfaces and interactions are identified (particularly during design and tradeoff analyses)Ensure interfaces are addressed and captured in ICDs or in system specs for intra system. Ensure requirements allocation documents are generated that specify what systems do in terms of satisfying allocated and interface requirements.
