Yep, I relate to that. I used to work for McDonnell Douglas, and it was back when they were trying to build the B-12 Stealth Bomber (I hope that's the right name, they kept changing it).
Most of the departments didn't know what the other departments were doing. I had a Top-Secret security clearance, and I was like one of the only people who knew EVERY part number for the plane, because I had to put together the files to give the designers and graphic people and sheet metal people the plans to put the parts together.
They made me make changes daily, first use this many bolts, no, this many, no this many. Change this shape of this wing, etc. I think the stupid plane failed because no one could decide how to build it. LOL!
