The SEI supported a large, multi-segment, software-intensive system program for six years. During this time, the SEI team observed technical, organizational, and management situations that affected the overall execution of the program. This paper records some of the observations and describes suggested (and, in some cases, implemented) solutions—for both historical purposes and for their potential benefit to future programs.
