Can you comment on this from the perspective of how the method works, as in the results it produces and why, as opposed to whether it's standard/common or not?

Can you comment on this from the perspective of how the method works, as in the results it produces and why, as opposed to whether it's standard/common or not? To me, SpaceX is remarkable because they've done what the rest of the world failed to do for 20 years. That's of course a combination of factors - vision, drive, start-up mentality - but are their actual processes/development methods also in any way better than in traditional space companies?
