If you want to know why Constellation is such a godawful mess, here’s one reason:
NASA JSC Center Director’s Systems Engineering Forum Planned Aug. 21
There actually are people out in private industry (like me) who do this stuff for a living, or at least would, if NASA would give them a contract. But instead of putting out a SETA or some other support contract for systems engineering, as Steidle had planned to do, Dr. Griffin simply decided that NASA would do it. This is where it’s gotten him. Had he hired a good SE contractor (and listened) the program would likely not be in the kind of trouble it is, either technically or politically. Of course, it would probably look much different, because a proper systems-engineering approach would never have resulted in the Shaft. That was the danger inherent in putting a rocket scientist in charge of the agency. He thought he was smarter than everyone else.
