supplier-nonconformance

# Raising a supplier nonconformance A weak nonconformance gets a denial and a month of correspondence. Make it undeniable. ## Include PO and delivery note · part number and revision · quantity received and quantity affected · the requirement, quoted from the drawing or specification with its revision · what was measured, with the instrument and its calibration date · photographs with a scale in frame · the batch or heat number. ## State the impact in their terms Line stopped, orders at risk, rework hours, and whether the material is quarantined or returned. Impact is what gets a nonconformance prioritised at their end. ## Ask for three things, with dates Containment — what they are doing about material already with us and in transit · root cause · corrective action, with verification. Containment has the short deadline; root cause does not. ## Never Raise against the wrong revision of a drawing, accept "no fault found" without their inspection data, or scrap affected material before the supplier has had the chance to inspect it.
