NASA's ASK (Academy Sharing Knowledge) resource, part of their APPL (Academy of Program and Project Leadership) site, contains a wealth of valuable lessons learned. We'll be frequently featuring these lessons learned on PMThink, and I encourage everyone to explore NASA's site for additinal lessons. By bravely and openly sharing these lessons publicly, they are truly doing a service to the project management industry.
Oh, of course people will point to NASA's well-publicized tragedies. No doubt there were some huge errors in judgment (and/or communication gaps). But their projects are an order of magnitude more complex than what anyone else is attempting, so naturally the stakes and the impacts will be higher (not that it's an excuse for human tragedy). Of course, with big mistakes, come big lessons. With some of the most extraordinary achievements in humankind (and just as importantly, its extraordinary disasters), NASA is the ideal place to turn to for project management lessons.
Check out this story for example, with lessons from the Galileo project in 1982. In addition to the obvious lessons of the importance of the project manager, and the project manager's role in selling the project, another key lesson is the ability to recognize when tradeoffs must be made in time, scope, or cost in order to assure a more successful project.
In this case, NASA realized that the best way to get to Jupiter was via a "gravity assisted" loop around Venus. This extended the time it would take to get to Jupiter threefold, but the resulting launch energy would make the project more successful.
