From the report: "DOD estimated that it had 1,731 business systems for its day-to-day operations as of October 2002. As GAO previously reported, these systems have evolved over time into the overly complex, error prone, duplicative, stovepiped environment that exists today. To support the operation, maintenance, and modernization of its business systems, the department requested approximately $18 billion for fiscal year 2003. Funding is only part of the solution to improving DOD’s current system environment. A key ingredient to success is effectively managing and overseeing these investments."
