MOSA enabling standards can best be described as widely accepted, supported and consensus based standards set by recognized standards organizations or the marketplace. Other benefits during the sustainment phase of a major system.Interoperability, including system of systems interoperability and mission integration.Opportunities for technical upgrades and refresh.Schedule reduction and rapidly deploy new technology.DoD seeks to yield the following benefits with a MOSA: This approach integrates technical requirements with contracting mechanisms and legal considerations to support a more rapid evolution of capabilities and technologies throughout the product life cycle through the use of architecture modularity, open systems standards, and appropriate business practices. Complies with the technical data rights set forth in 10 U.S.C.Uses a system architecture that allows severable major system components at the appropriate level to be incrementally added, removed, or replaced throughout the life cycle of a major system platform to afford opportunities for enhanced competition and innovation.Documentation with functional descriptions of software-defined interfaces, conveying semantic meaning of interface elements, such as the function of a given interface field.A machine-readable definition of the relationship between the delivered interface and existing common standards or interfaces available in Department interface repositories and.Software-defined interface syntax and properties, specifically governing how values are validly passed and received between major subsystems and components, in machine-readable format.Is subjected to verification to ensure that relevant modular system interfaces comply with, if available and suitable, widely supported and consensus-based standards or are delivered pursuant to the requirements established in FY21 National Defense Authorization Act Section 804 (a)(2)(B), including the delivery of.Employs a modular design that uses modular system interfaces between major systems, major system components and modular systems.

4401(b), states all major defense acquisition programs (MDAP) are to be designed and developed using a MOSA that.

A MOSA is the DoD preferred method for implementation of open systems, and it is required by United States law. A Modular Open Systems Approach (MOSA) can be defined as a technical and business strategy for designing an affordable and adaptable system.
