i've done a lot of contract work for spacex. imo i think part of the reason they work so much is because they have no formal methods group. everyone seems to solve similar problems in slightly different ways instead of having a vetted and documented 'right' way to approach certain things. i've literally been paid to write code that does the same thing for different groups in slightly different ways. having done a lot of aerospace contracting, this is atypical from what i've seen elsewhere. my point is that if they formed a methods group to formalize and standardize across the entire org they might be fine with a 10% cut if they're not duplicating efforts all over the place.
