"Instead of one great power rival, the United States now faces a series of transregional, cross-functional, multidomain, and long-term strategic competitions that pose a significant challenge to the organization of the Pentagon and the military, which is often rigidly aligned around functional issues and regional geography. Put simply, the Goldwater-Nichols Act of 30 years ago was about operational effectiveness--improving the ability of the military services to plan and operate together as one joint force. The problem today is strategic integration--how the Department of Defense integrates its activities and resources across different regions, functions, and domains, while balancing and sustaining those efforts over time. The NDAA would require the next Secretary of Defense to create a series of "cross-functional mission teams" to better integrate the Department's efforts and achieve discrete objectives. For example, one could imagine a Russia mission team with representatives from policy, intelligence, acquisition, budget, the services, and more. There is no mechanism to perform this kind of integration at present. The Secretary and the Deputy have to do it ad hoc, which is an unrealistic burden. The idea of cross-functional teams has been shown to be tremendously effective in the private sector and by innovative military leaders, such as GEN Stan McChrystal. If applied effectively in the Office of the Secretary of Defense, I believe this concept could be every bit as impactful as the Goldwater-Nichols reforms."
