## What project 123 buys

Mission Engineering and Integration is a strategically driven, mission-focused framework designed to synchronize concepts, requirements, research and engineering, budget, and programs across the DoW, integrating cross-Service capabilities to deliver timely and accurate end-to-end mission effects. It performs the following functions: • Carries out responsibilities described in the National Defense Authorization Act for FY 2017, Section 855 (Mission Integration Management) by conducting rigorous mission engineering activities to identify and prioritize investments in capabilities with the greatest potential to meet current and future warfighting needs, address warfighting gaps and joint operational problems, and enable Joint Force interoperability and integration. • Executes a variety of Joint Force Integration Mission Engineering analyses and studies in support of the National Defense Strategy—aligned with Defense Planning Scenarios and Key Operational Problems—that evaluate the mission impacts of integrating new technologies and capabilities into critical warfighter missions. • Harnesses modeling and simulation (M&S) tools and advanced techniques to develop and analyze critical Joint Mission Engineering Threads (METs)/“Kill Webs” in operational scenarios, enabling DoW leaders to make informed technology investment decisions. • Develops digital, reusable, enterprise-level Joint METs that are used to assess and evaluate system-of-systems dependencies and risks in executing end-to-end missions. • Maintains the Mission Engineering Guide and related guidance, and leads the Mission Engineering Practitioners Forum to share lessons learned, pain points, and advance the state of the practice of Mission Engineering. • Increases collaboration with industry by utilizing technical information exchange agreements to share sensitive data. These efforts identify material solutions that address operational gaps and mission requirements, building public-private partnerships that inform technology, modernization, research, and applied engineering investments.

### Mission Engineering and Integration

• Perform and scale a variety of Joint Force Integration mission engineering analyses and studies aligned with Key and Joint Operational Problems and critical warfighting missions. These efforts identify technologies and capabilities that enable Combatant Command Operational Plans and operationalize the Joint Warfighting Concept (JWC)…
