Boeing culture has been going down for quite some time.
The pivotal point to me was, when Airbus launched the A380, Boeing thought they would have an easy home run with the Dreamliner, Airbus would be doomed as competition as no one wants the A380, Boeing slacked off, and then Airbus came back, listened to the customers, changed the A350 to a new plane and had a runaway success (on top of the bread and butter neos).
