The idea of DFM is that any reasonably skilled engineer creates a design such that any reasonably skilled manufacturing/assembly shop can put it together.
Without following the practices of DFM, it is more likely than not that some part of the assembly will be done incorrectly, even if the assembly team was highly skilled and executing at a high level of competence.
With DFM, a moderately skilled EE, and a moderately skilled assembly team, will correctly manufacture the designated system.
- ajross 13y agoTrue, but missing the point. DFM can be misapplied, as it was here. So now you need to propose a process (design review, I guess) that prevents DFM from being misapplied. And that process can break down... The fact that you can look at the wreckage or a rocket and "see" what the problem was in hindsight is not proof that you know how to prevent any such accident. I really with more design people understood that. (It doesn't mean that whatever process you favor is a bad idea either, but that it has limits. Getting to my original point: you can't fix bugs by executive fiat.)
