摘要

Daniel Adamo was right on in castigating "faster, better, cheaper" philosophies as the wrong way to get to Mars ["Humans to Mars in 20 Years: A Faster, Better, Cheaper Sequel?" Commentary, June 29, page 19]. But he didn't go far enough. Adamo was correct in citing the need for a dynamic equilibrium among the three key attributes of the aerospace trade space: schedule, quality and cost. He was also correct in identifying risk acceptance, the unavoidable consequence of constraining cost and schedule, as the road to disaster, and in emphasizing that quality (read "reliability") must always come first, especially in human missions. So how do we find that elusive dynamic equilibrium in the trade space? There is a clear, straightforward way to do that, and to maximize the probability of success, but that path is, unfortunately, contrary to the tenets deemed important by those in charge of large aerospace programs, and is therefore largely unacceptable to them. What's the secret? It's a very simple one that I suggested over a decade ago and is perhaps even more pertinent today, with the rash of recent Mars proposals: Put no limits on scheduled completion of the project or its total cost.
