Shortcomings in the requirements engineering processes are emphasized. We review incremental acquisition approaches and identify issues essential to successful application of incremental acquisition approaches to overcome these shortcomings. In identifying these issues, cases based on systems being developed by the Air Force Space Command are examined. They are the Granite Sentry (GS), Space Defense Operations Centers (SPADOC), and Mobile Command and Control System (MCCS) programs. Three key aspects of the lessons learned from these efforts parallel the steps suggested by a recent Air Force Studies Board report for reducing risk in developing unprecedented systems. These are team-based development, managing requirements uncertainty and change, and increased use of incremental acquisition approaches.
