When a supplier fails, it is your part, your late line and your customer's escape. Your customer does not distinguish between what you machined and what your anodizer coated: both arrived under your certificate of conformance. AS9100D makes the same point in its own way: you stay responsible for the conformity of everything you buy, and the type and extent of control you apply to each supplier should follow from the risk it carries (8.4.1, 8.4.2).
We have seen the same patterns in almost every supplier control system we have looked at, large or small:
- An approved list that approves companies, not work. 'Approved' against every name, no scope, no conditions. A buyer places a new part with a supplier assessed for something else, and nobody can tell.
- Sub-tier sources nobody has asked about. The heat treater, plater or NDT house your machining supplier uses on your parts has never appeared on any list, and is doing your special process.
- Certificates filed, not read. Receiving ticks 'certificate received'. The heat number, the specification revision and the results are never compared with the purchase order or the material.
- A scorecard that is a feeling. The supplier that let you down last week feels like the worst; the one that slid from 98 to 88 percent on time goes unnoticed until it is a line-down.
- Corrective actions that close on paper. 'Operator retrained' is accepted because chasing is exhausting, and the same defect comes back under a new NCR number.
- Status changes that change nothing. A supplier goes on probation on the list while receiving inspects its lots exactly as before.
- Expedite calls instead of a plan. A key supplier in trouble gets daily calls from purchasing, quality and operations, each asking for something different, and nobody has written down what 'recovered' means or what happens if it doesn't.
None of these is solved by a better form on its own. They are solved by a small number of controlled records that talk to each other, a few clear rules about what each status and rating changes, and a short, regular rhythm of review. That is what this kit gives you.
