In response to a request from the House Committee on Science, Space, and Technology, the General Accounting Office (GAO) presents information on NASA's efforts to improve shuttle software oversight activities and to establish independent oversight of critical shuttle software processes. GAO identifies NASA's procedures for developing, validating, verifying, and reconfiguring shuttle software. GAO also notes recommendations made by the independent contractor hired by NASA to verify and validate shuttle software; problems hindering NASA's progress in implementing the recommendations; actions taken by NASA to specifically resolve concerns raised by the National Research Council (NRC) and the shuttle program's software steering group formed to recommend changes in the verification and validation processes; and GAO's recommendations. Included as an appendix are NASA's comments on GAO's findings.
