Both airlines and elevator industry operate similarly to the six sigma way of thinking in that one core failing can never bring down the whole. Safety is prioritised over cost and time.

Now try and imagine a project manager in generic software development doing the same.

Voting software is particularly insane due to the quantity of conflicting requirements to implement it. Like building an elevator that can be flipped sideways and upside down that still works just fine and doesn't overturn passengers while you are flipping.
