Description:  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.

OUSD (R&E) SE&A, along with DAU recognize the importance of creating a Department of Defense (DoD) Modular Open Systems Approach (MOSA) Roadmap. This roadmap will guide the future direction of MOSA, with the aim of enhancing team awareness, capitalizing on strategic partnerships, using key data resources, fostering alignment across different disciplines, and setting priorities for future tasks.
