Use/relationship:

The essence of Open Systems Architecture (OSA) is an organized decomposition, using carefully defined execution boundaries, layered onto a framework of software and hardware shared services and a vibrant business model that facilitates competition. An Open Systems Management Plan (OSMP) describes the developer's approach for using modular design, standards-based interfaces, and widely-supported, consensus-based standards to achieve these goals. The OSMP shall include a developer's plans for a modular, open architecture, to include use of open interface standards and Technical Reference Frameworks (TRF); design and management of, and dependencies between, Computer Software Configuration Items (CSCIs); design information documentation; technology insertion; life cycle sustainability; treatment of proprietary or vendor-unique elements; and reuse of existing items. The OSMP includes a support plan for the Modular Open Systems Approach (MOSA) and provides the acquirer visibility into the developers' open systems approach and implementation.

This forms a basis for evaluation of a developer's proposal and adherence to MOSA technical and business goals.
