What to do when a customer tightens a tolerance mid-contract
When a customer tightens the tolerance halfway through a contract, start on the next roll after the written change arrives. Rolls already passed on the old tolerance are not rejudged, unless the written change says to go back. Keep both numbers on the job ticket.

Why call it this way
Sales saying on the phone that the customer wants it tighter gives the press nothing to run to. Ask them to send the number and the roll it starts on. Until then, keep the number in the contract, and tell sales what the number is now. When both numbers are live, swap the inspection template to the new one and change the version.
Side by side
| What you see | Call | Do not |
|---|---|---|
| A written number and a start roll | Run from that roll | Trace back to the day of the phone call |
| A spoken request only | Get it in writing first | Let the operator invent a tighter number |
| Old rolls already passed, and the change is not retroactive | Keep the original call | Fail the whole lot again |
Check at changeover or roll start
