## Highlights

GAO has designated the Department of Defense's (DOD) business systems modernization as a high-risk program because, among other things, it has been challenged in implementing key information technology (IT) management controls on its thousands of business systems. The Global Combat Support System-Marine Corps program is one such system. Initiated in 2003, the program is to modernize the Marine Corps logistics systems. The first increment is to cost about $442 million and be deployed in fiscal year 2010. GAO was asked to determine whether the Department of the Navy is effectively implementing IT management controls on this program. To accomplish this, GAO analyzed the program's implementation of several key IT management disciplines, including economic justification, earned value management, risk management, and system quality measurement.
