Exactly! All this talk about man vs system misses the point that man is the system designer, operator, and component.

This is why Boeing cant just solve their situation with more process checks. From the reporting, they are already drowning in redundant quality systems and complexity. What failed was the human elements.

Someone was gaming the system saying that the doors weren't "technically" removed because there was a shoelace (or whatever) holding them in place, Quality assurance was asleep at the wheel, and management was rewarding those behaviors.

Plenty of blame to go around.
