Boeing considers Quality Assurance to be a liability, inspectors on the floor have to deal with production management on a daily basis that are trying to meet a schedule. Managers performance is based on the schedule being meet and bonuses are based on meeting the schedule. I have seen know defective parts being installed just to meet a daily schedule.
The current FAA Policy of letting manufactures certify their own product, ie ODA, has let the fox in the hen house, this policy is also contributed to the 737 MAX debacle, should have never happened, Congress was a sleep again.
