I couldn't disagree more. Outside of exotic scenarios where things like formal proofing are possible and economically viable I've never seen a process that prevents bugs, only culture. Good engineering cultures are also often ones with well defined and tested processes and good testing practices but it's the culture and people giving a shit that makes the difference, not the other way around.

Good product cultures are ones where natural communication between the field and engineering would mean issues get reported back up and make their way to the right people. No process will compensate for people not giving a shit.
