What the quality manager should look at every Monday

Look at only three items. Use counts, not a feeling. Clear the undecided rolls.

A simple chart of a week’s defect counts

Every Monday the quality manager looks at three things: the three defects with the highest counts, the one false-reject type with the highest count, and whether any flagged roll is still undecided. Do not look at thirty pages of curves. If these three have numbers, the week’s adjustment has a target.

Why it is judged this way

Monday time is short. One sheet: on the left the counts of three defects, on the right the rolls not closed. The one that has risen for two weeks in a row is the roll or the blade to check this week. If nothing has risen and there is no complaint, do not change the threshold.

What to compare

What you see What to call it What not to do
One defect keeps rising Check the matching roll, blade, or material Change the threshold first
False rejects cluster on one material Change that material’s zones Loosen everything
A roll is undecided past one shift Clear those rolls first Look at the charts first

At job change or when a roll is opened

  1. Export last week’s three most frequent defects.
  2. List the undecided rolls.
  3. The meeting decides only which one item to change.
