Re-check of today's lots

Line	Shift	Lot	With burr
Line 1	06–14	81	0 of 40
Line 2	06–14	82	0 of 40
Line 3	06–14	83	0 of 40
Line 3	14–22	84, 85	7 of 40

Sample re-check at the fictional plant Wendt Gussteile. Lines 1 and 2 and lot 83 from line 3, early shift: 0 of 40 lids with a burr. Line 3, late shift, lots 84 and 85: 7 of 40 lids with a burr. A tool change took place on line 3 at 14:00.

Step 1 of 4

A customer reports housing lids with a burr on the sealing face. The re-check gives this table. What do you quarantine first?

Every part from all three lines made today.All parts from line 3 after 14:00: lots 84 and 85.Only the 7 lids found with a burr.

About this activity

What you practise: You scoped a quarantine by the evidence, kept two suspected causes open, counted only checked good parts as shippable and tied the end of the tighter check to closed open points.

A hand-written example with a fixed sequence. It shows what working on a Klarisma activity feels like; your own activities follow your goals and material.

The burrs appear only on line 3 after 14:00. You quarantine the whole lots 84 and 85, not just the 7 lids found: a sample never shows every faulty part.
