This conversation reminds me of an electronic relay assembly line I once observed over a period of time. The workers hand-soldered relays, their numbers were being measured/judged, so many cold welds were shipped. QA sent them to soldering classes, where temperatures and flowing of solder were discussed/practiced. They came back with nicely soldered joints, and production numbers dropped to the floor. Management came back in, exhorting higher numbers, so out came the cold welds again to make the numbers.
