SYSTEMS ENGINEERING - BEYOND MIL-STD-499B OR THE BRILL PARADIGM OF SYSTEM ENGINEERING

This paper goes beyond the systems engineering construct of MIL-STD-499B and suggests private and public enterprises would benefit from viewing systems engineering as a “system.” The suggested paradigm (model) synthesizes the author's original concepts, portions of MIL-STD-499B (Draft, May 1992) and proceedings of the 23–25 October 1992 NCOSE sponsored committee meeting on a systems engineering capability maturity model. The model's concentric design incorporates the system elements and system primary functions of MIL-STD-499B, but moves the “customer” bulls-eye to an outer-ring labeled “Business Environment,” and identifies people, process, and technology as the three key components of systems engineering. Each of the key components is decomposed to lower levels of detail. The paradigm presented is intended to have universal application and not be limited to defining, evaluating, and improving systems engineering efforts in defense system acquisition and technology programs. Lastly, it is hoped that the paper's content will stimulate others to take a more “systems” view of “systems engineering.”
