The general standards of aviation production and maintenance are so stringent that I would think that isnt the reason. Parts of an airplane are supposed to be fully logged and tracked basically from manufacture (of the part itself) through the life of their use on an aircraft, in high detail. All tools used in building or maintaining an aircraft are the treated the same way, even a simple screwdriver, because you dont want to leave stuff behind in an aircraft.
This was 200% a process issue and not a design issue with the door itself. If everyone is following process standards to a T then nothing like this should have ever been remotely possible.
There is a reason why Boeing used to keep its main headquarters right down the street from where they manufacture in Washington state. Now they cant keep as tight of control on their plant(s)
Research FMEA. They will review the existing FMEA for all the door components and decide how best to solve the issue. In this case it is a safety FMEA.
