Look at every possible failure mode of every component, down to the tiniest screw or wire or bit of plastic. Keep redesigning parts until you eliminate all failure modes that you don't have triply-redundant backups for. Test the living snot out of everything on the ground, in the lab. Have massive technical and safety reviews to ensure nothing was missed, anywhere.It worked about as well as anything could, but it was extremely slow, bureaucratic, and above all incredibly expensive. Tons of rework when issues were found meant having to go back 3 steps to change something, and then redo the massive amount of work that had been done since then to make sure no new failure modes were possible, etc.SpaceX is doing things differently - <a href="https://mindly.social/tags/iterative" class="mention hashtag" rel="nofollow noopener" target="_blank">#iterative</a> design. You design, build, <a href="https://mindly.social/tags/integrate" class="mention hashtag" rel="nofollow noopener" target="_blank">#integrate</a>, and <a href="https://mindly.social/tags/test" class="mention hashtag" rel="nofollow noopener" target="_blank">#test</a>-to-failure as often as possible to learn where the weak spots are -- you then rapidly iterate when you find the problems. "Rapid Unscheduled Disassembly" is an expected part of the process - it's how you learn the limits of what you've built, where the problems are.Neither one is "the right way". They both work.<a href="https://mindly.social/tags/IterativeDevelopment" class="mention hashtag" rel="nofollow noopener" target="_blank">#IterativeDevelopment</a>
