LOL. Nobody who works where a product is being made wants to have one.
The Sausage Factory Blues.
Back in the '70s I knew a guy who worked at a major automaker factory (sorry, can't recall which one) for the summer. His job was to work on the line that assembled differentials.
They had this very expensive "computerized" machine that would measure the parts -- he'd pick up the gear or shaft or whatever, stick it in the machine, wait for the machine to think it through, and then read off the number on the display that told him which shim-washers to stick on the shaft (there were several thicknesses of washers -- the machine would tell him how many of each to install, so that each rear end would have the right amount of play, gear lash, etc.)
The machine had four "stations" -- four guys ran it.
My friend was unable to keep up with any of the other three workers, even though he was working as fast as he could, once he saw the numbers pop up on the display.
One of the other workers says to him, you're gonna get in big trouble for working too slow, you're gonna get fired, dude. He replies, hey, I'm going as fast as I can, but I can't do anything until the machine tells me which shims to put in!
The guy laughs at him, and says watch me, I'll show you how to do it.
A piece comes down the line. He takes it. He grabs a bunch of random shims, sticks 'em on the shaft, drops on the gear, and sends the assembly down the line. He says "I take one of these, two of these, and one of these" (or something along those lines), "and there ya go!"
My friend can't believe what he's seeing. He says, but, none of your pieces is gonna be within tolerance! They won't be any good!
The guy laughs and tells him that's someone else's problem, the main thing is to keep up the volume.
Oh, sure, some rear ends will be so loose that they whine like a baby, and wear out in short order, and some will be so tight that they'd overheat from the friction (and rob MPG), and fail in short order... but hey, that's someone else's problem.
Welcome to the kind of "quality control" that sent Americans screaming to the Japanese dealerships.
