Commercial and institutional markets place high pressure (time and cost constraints) on companies designing and developing satellites and payloads. Those markets reward companies able to either inject disruptive solutions or identify reusable patterns (e.g. from past projects) and implement incremental improvement by exploiting heritage and available processes. Patterns usually can be identified in different domains of the realization of a space system: design, development, and verification. Yet it often is not trivial at all to identify patterns because of the lack of a taxonomy and ontology, as well as because of the complexity of the working framework of a project. Under such boundary conditions, the design and management of interfaces emerge as critical aspects of system engineering, given the complexities in system interactions.
