The goal of reducing the cost of equipping Army vehicles with new capabilities, while adding increasing interoperability and flexibility of operation, can be accomplished through the use of a Modular Open Systems Approach (MOSA), a technical and business strategy for designing an affordable and adaptable system.
MOSA, the U.S. Department of Defense (DoD) mandate for modular open system design, is the preferred method for implementation of open systems, and is required by U.S. law, which states all major defense acquisition programs (MDAP) are to be designed and developed using a MOSA that:
- Employs a modular design that uses open system interfaces between a major system platform and a major system component, between major system components, or between major system platforms;
- Is subjected to verification to ensure major system interfaces comply with, if available and suitable, widely supported and consensus-based standards
- 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.
