It's also fair to say that if you let the marketers drive business decisions it's a recipe for disaster. Pushing low-quality product out the door just to hit some quarterly sales goal, that's what marketers will push. Epic failures with disastrous long-term consequences are the typical result (Boeing MAX for example).
My understanding was that Boeing wanted to prevent Airbus from winning contracts and so pushed the schedule hard. That's the sales and marketing division talking isn't it?
