# 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.
