This is a ground up production launch. There is no such thing as a smooth ground up design production launch from the perspective of inside the factory. All of the emotion, the drama, the frustration, is to be expected when the designs of thirty people are suddenly subjected to 150 sets of hands doing all sorts of things we don't understand. This is the engineer's battle. This is his experience. This is why experience matters, because it's only painful memories that describe why we need 10 mm minimum between moving surfaces, even when they are machined. My oh my, what I have learned about clearances and tolerances the last month.
