DoD MOSA is an integrated business and technical strategy to achieve competitive and affordable acquisition and sustainment of a new or legacy system or component over the system life cycle. This approach allows the Department to acquire warfighting capabilities, including systems, subsystems, software components, and services, with more flexibility and competition.

 MOSA compliance is instrumental in developing acquisition systems while reaping the benefits of reduced cost and schedule. Evaluating system architecture for MOSA compliance can be achieved by leveraging  Digital Engineering. We will explore how this Model Based Systems Engineering (MBSE) process provides confidence that MOSA-based architecture development will result in cost and schedule savings. Our approach uses MOSA Quality Attribute (QA) criteria to evaluate architecture requirements prior to system design. Our goal is to provide early confidence in architecture that fosters MOSA principles.
