I'd say Learning Culture is also a problem. Boeing has made numerous missteps in the last 15 years after being the world leader in airliners for around half a century. This only happens when knowledge about how to make a safe product is purposefully discarded and attempts to bring that knowledge back are intentionally ignored. In Boeing's case, it's due to desires for increased profits. They are unwilling to learn these lessons because it costs money that _may_ be there at quarter's end.
