Summary: GAO examined how best practices could help the Department of Defense (DOD) maximize the benefits of integrated product teams in its development of weapon systems. GAO conducted eight case studies--three from leading commercial firms; four from DOD programs experiencing cost, schedule, and performance problems; and one from a DOD program that has been meeting its objectives. GAO found that effective integrated product teams can make significant development decisions quickly and without relying on heavy consultations with organizations outside of the team. These teams have developed and delivered superior products within predicted time frames and budgets--often cutting calendar time in half compared with earlier products delivered without such teams. Officials from the more successful programs GAO reviewed--three commercial and one from DOD--all cited integrated product teams as a main factor in achieving such results. GAO found that the teams did not operate as effectively in the four DOD programs that were not meeting cost and schedule objectives. Their decision-making processes were sequential and involved many outside consultations for information and approval.
