I worked at Boeing. The reason people attribute McDonnell Douglas is because it caused a fundamental shift in leadership expectations.

It was clear as day on the ground that something had switched, suddenly every conversation was about minimizing cost. Every meeting was about maximizing value. Efficiency above safety.

I cannot overemphasize that it really did fundamentally shift the language, the incentives, etc. I started having to prove I needed vms to two different business panels.

Sometimes you are right, the root cause is too simple, but I was there for this one. It really was that simple this time.
