I've been spoiled by modern technology more than I thought; I forgot draftsmen!
So, here's how an experienced team works.
The engineer realizes that the tank will be So Much Better if parts A, B, C, D, F, and Q have a 0.5" radius here rather than a 0.25" radius. He goes to the draftsman and says "Change this radius on A, B, C, D, F, and Q to 0.5"." The draftsman does it, and hands the new drawings to the shop foreman. He doles the new drawings out to the six machinists who will be making A, B, C, D, F, and Q today. They make the new parts.
Here's how a raw team works.

He goes to the draftsman and says "Change this radius on A, B, C, D, F, and Q to 0.5"." The draftsman says "OK, which radius on C did you mean, this one or that one?" "That one. Isn't that obvious?" "No." "Well, OK, that one." The draftsman does it, and hands the new drawings to the shop foreman. He doles the new drawings out to the six machinists who will be making A, B, C, D, F, and Q today. The guy making A thinks he knows what to do, and it will be two days before QC finds the problem and traces it back to him. The guys making B, F, and Q know they're out of their depth and appeal back up the chain for help, which results in the engineer coming down to the shop and the conversation in my prior post occuring. The guy making C actually figures it out on his own. The guy making D doesn't see what the big deal is and keeps making the old parts, figuring if he can't tell the difference, no one else can either.
