8.4.1ISO 9001:2015

Externally provided processes, products & services — general

Plain-language summary

Everything you buy that ends up in or affects your product must conform — so evaluate, select, monitor and re-evaluate providers against defined criteria, and keep the records.

What the clause is really asking

Applies when supplier product is incorporated into yours, delivered direct to your customer, or a process is outsourced. Determine controls, set criteria for evaluation/selection/performance monitoring/re-evaluation, retain records of all of it and of resulting actions.

What auditors look for

Auditors ask for the approved supplier list and the criteria behind it, then sample: how did this supplier get approved? Latest performance review? What happened to the chronic underperformer? Outsourced processes get the same questions.

Typical evidence

Supplier evaluation criteria and records; approved supplier list; performance monitoring data; re-evaluation/exit records.

How to comply — recommendations

Risk-grade your suppliers (product impact x performance) and scale effort accordingly — heavy controls on the critical few, light touch on commodity. Review the list at management review.

Common nonconformities

Buying from unapproved suppliers; evaluations done once at onboarding then never again; poor performers tolerated without development or consequence.
