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

  1. Ask the customer for the new tolerance in writing.
  2. Write the first roll the new number applies to.
  3. Change the template version.
