Beyond the JCIDS and the JROC: Mission Engineering for Accelerated Operational Design

Abstract

The Department of Defense (DoD) faces a persistent gap between rapid commercial innovation and the slow, requirements-driven processes that historically shaped military capability development. Legacy frameworks such as the JCIDS and JROC often constrained the warfighter’s influence, limiting their ability to shape the systems they ultimately rely on in operational environments. Their recent disestablishment and replacement by mission-driven constructs, including the Key Operational Problems framework and the Mission Engineering and Integration Activity (MEIA), signal a shift toward capability development that centers operational outcomes and restores the warfighter’s role in defining them (Hegseth & Feinberg, 2025; Joint Staff J8, 2021). Mission engineering provides the structure needed to realize this shift. By grounding capability development in executable mission threads and shared digital engineering environments, mission engineering creates a continuous feedback loop in which warfighter experience and operational learning directly inform architecture updates. This closes the long-standing disconnect between operators and designers and enables earlier system-level integration, virtual validation of operational effects, and faster iteration as threats evolve (Office of the Under Secretary of Defense for Research and Engineering, 2023). Building on this foundation, the paper introduces Mission Thread Integration Leads (MTILs): engineering organizations responsible for assembling and integrating distributed emerging technologies into coherent mission architectures before formal acquisition. MTILs complement MEIA’s government-side mission engineering role by providing an industry mechanism for iterative experimentation, digital integration, and mission-thread-level maturation of capability driven by real operational needs (Hegseth & Feinberg, 2025). By aligning the Department’s new mission-driven governance structures with a warfighter-centered engineering approach, MTILs offer a practical path to close the integration gap and accelerate the transition from technological innovation to operational advantage. This paper outlines the policy, workforce, and digital infrastructure investments required to institutionalize this model and fully realize the DoD’s transition from the JCIDS and JROC to MEIA (Hegseth & Feinberg, 2025; Joint Staff J8, 2021).
