Same thing down on the production floor. Each program (737, 767, etc) has its own part number series. I'm sure there has to be some parts commonality, somewhere, with the same part getting two different numbers printed on it at the factory, but I saw no hint of it happening.
Fun fact: the two big Puget Sound factories (Everett and Renton) number their hand tools differently. It's true. A socket wrench will be EVT12345 or whatever, and the same tool in Renton will be inventoried differently.
The two factories have very different cultures. Renton does two planes a week, Everett does one plane a month. There was much grumbling during the webinars and retrainings after the Door Plug Incident that all this was being inflicted on us because of the cowboys down in Renton and their maniacal obsession with production rate, something which is not quite so much a focus at Everett.
