Methodology to Establish Enterprise Modularity

Execution of a Modular Open Systems Approach (MOSA) on government procurement programs is enacted into United States law (Ref. 1-2) and, if implemented properly, can enable more efficient accomplishment of business and technical objectives for an organization (Ref. 3-8). Open Systems are well defined (Ref. 9) and mature. Successful implementations of open standards have governance and conformance processes associated with them (Ref. 10-12). By using open system standards for integration of complex cyber-physical systems, like Future Airborne Capability Environment (FACETM) (Ref. 13) and Open Mission System (OMS) (Ref. 14), it is a straightforward exercise to determine if open system requirements of a MOSA are adequately addressed. However, adherence to these standards alone is insufficient to fully realize MOSA’s benefits (Ref. 10). This paper focuses solely on how to develop enterprise modularity as one part contributing to a comprehensive enterprise MOSA strategy.
