I don't think that's quite the case. SpaceX's method is more "release early, release often", and find (and solve!) issues early on. Traditional space companies on the other hand use a very rigid waterfall method. SpaceX's method is not "fuck around and find out". It's design, find out, iterate. From what I can tell from the outside, it seems very reasonable.
