How do we win this game when the ruleskeep changing?

摘要

We all know the goal of the game: “Develop increasingly complex systems withrnsmaller performance margins that meet the user’s requirements in the shortest time, with highrnreliability, open and adaptable, and at the lowest cost”. The environment we are working inrncontinues to push Systems Engineering challenges to the next level. As Systems Engineers, wernall want to win the game I.e. beat our competitors, satisfy our customers, develop unprecedentedrnsystems to address political and economic challenges. We have a proven process and a commonrnset of tools, which we use and refine. Yet as we begin to participate in the game, we find that notrnonly do we have huge challenges, but the rules keep changing. The customer/user requirementsrnchange, the conceptual design needs modification, the analysis reveals design challenges,rnbudgets are reallocated. So how do we win this game? This paper presents a case for thernincreased application of a suite of enablers, processes, and practices referred to as Design for SixrnSigma at appropriate integration points during the Systems Engineering process lifecycle.
