Abstract : The use of some degree of concurrency in weapon system acquisition has become a normal mode of operation. There are several benefits and problems associated with concurrent programs. The recent elevation of reliability and maintainability (R&M) to a status equal to performance, cost, and schedule when evaluating current weapon systems has added to the list of potential problems experienced by concurrent programs. A literature review was conducted which traced the history of concurrency from the Ballistic Missile Programs to the 1986 Packard Commission Report. This review focused on the reasons for the continued discussions on the overall value of concurrency. The review also looked at the impact of concurrency on system R&M. Several factors were identified which existed in concurrent programs and showed a potential to limit system R&M. In addition the study covered the causes for the variances between the system R&M measures demonstrated in the developmental and operational environments. The results of this study indicate that concurrency does impact system development. However, the amount of impact and the applicability of the factors reviewed varies by program. Managers' opinions of the factors appear to be influenced by their position in the acquisition program. The benefits and programs of concurrency are covered. The causes for the disparity between field and development R&M measures, suggestions to correct this R&M problem, and recommendations to improve system R&M are discussed.
