8.4.3ISO 9001:2015

Information for external providers

Plain-language summary

Tell suppliers exactly what you need before they supply it: the processes/products/services, approval rules, competence requirements, interactions, your monitoring of them, and any verification you or your customer will do at their site.

What the clause is really asking

Communicate (after checking adequacy): requirements for what is provided; approval of products, methods, equipment, release; competence; provider interactions; control and monitoring applied; verification/validation activities planned at their premises.

What auditors look for

Auditors sample POs and agreements: are requirements complete and current (right spec revision)? Approval and release rules stated? Site-visit rights established where you rely on them?

Typical evidence

POs with full requirement references; supplier quality agreements; spec transmittal records.

How to comply — recommendations

Standardise PO text to reference the current spec revision and your supplier quality agreement. Keep proof of which revision was sent — revision confusion is the eternal supplier dispute.

Common nonconformities

POs referencing obsolete drawings; quality requirements assumed 'known'; no agreement on release or approval mechanics.
