Perry The Secretary of Defense Attention: DOD Office of the Inspector General Director for GAO Surveys and Reviews Dear Mr. Secretary: As part of our continuing work on the development and acquisition of embedded computers for major weapons systems, we have been reviewing the Air Force's F-22 aircraft program for the Chairman, Subcommittee on Research and Technology, House Committee on Armed Services. Our specific objectives were to (1) describe and assess the Air Force's strategy for developing embedded computers and software for the F-22 and (2) identify risks that could adversely affect the program. In August 1993, we briefed representatives from the Air Force and your office on the results of our review. We have done follow-up work since then on the actions being taken to address our concerns. The purpose of this letter is to highlight these concerns, as well as key issues that warrant your continued attention. Our review disclosed that the Air Force's planned strategy for F-22 software development, which was in its early stages, was generally sound in concept. Capitalizing on lessons learned, the strategy was intended to avoid mistakes that had hampered previous highly software-dependent programs and to give software more attention than had traditionally been the case. Noteworthy features of the strategy include (1) early assessment of contractors' software capabilities, (2) a commitment to be event, rather than schedule, driven, (3) use of integrated product teams to facilitate early identification and correction of problems, (4) use of a common software language (5) use of common automated software development tools, and (6) preparation of comprehensive software development plans that call for rigorous quality assurance and risk management Air Force F-22 Embedded Computers GAO/AIMD-94-177R
