The Department of Defense has recently charted a new course to further improve the way in which it provides weapon systems for the war fighter. This path has seen a fundamental change in how members of the Government/industry acquisition team work together to develop America's arsenal for defense. These changes center around the use of Integrated Process and Product Development concepts and the use of empowered, multifunctional teams, called Integrated Product Teams. Integrated Product Teams have been used successfully in industry for a number of years. One particularly successful example has been the use of Integrated Product Teams on the Boeing 777 program. Now several programs in the Defense Department are operating under these concepts. The earliest, and the leader in these concepts, is the Air Force F-22 Advanced Tactical Fighter development program. In this book, Lieutenant Colonel Michael D. Williams, USAF, first describes the principles and the concepts of the F-22 program.
