Most likely the audacious ideas like rocket to Mars come from Elon Musk and, Elon has the track record to not have to go lean.. If Rajesh proposed a rocket to mars, security will be called. But Elon must have also broken down spaceX to a process of validating some definition of MVP (power sub systems, insulation, inertial navigation and other fancy terms) that adds to the final product.. Overall I feel Erics lean startup approach is much more reliable that the deterministic approach used by investors to pick the winner based on how young the team is, since when they coded, where they dropped out off and how much in the fringe the idea is..
