ISO 9001 Clause 7.4.1, Supplier Control

Mr. Pareto Head and Supply Chain comic strip

Q: My interpretation of  ISO 9001:2008 Quality management systems–Requirements regarding supplier control as addressed in clause 7.4.1 Purchasing process is that suppliers who would require evaluation, selection and registry, would be those who supply products (or services) which affect subsequent product realization, or the final product.

Excellent examples for our organization would be vendors providing raw material, tool/dies, surface preparation or calibration services.

I also believe that the “extent of control” exercised by the organization, could, in fact, mean that certain suppliers are not controlled (evaluated, selected and registered), due to their lack of impact on product realization.

Good examples here would be stationery or sanitation supplies.

After conferring with several colleagues, we are all puzzled to see freight companies (UPS, FedEx) included as controlled suppliers and nonconformance reports written for failure to comply with the standard if they are not included on our approved suppliers list.

I understand the standard is written to provide a framework, and not examples, however I find this interpretation to be too broad for the intended purpose.

A: Thank you for contacting ASQ’s Ask the Experts program.  The intent of ISO 9001:2008, clause 7.4.1 is to ensure suppliers are selected based upon their ability to meet the organization’s requirements, which generally include quality and delivery of product or service intended for the customer.

As you mentioned, suppliers of office supplies such as paper, printer toner and etc. are not usually included on an approved suppliers list since they have zero impact on the organization’s ability to meet customer requirements.

However, some registrars may consider trucking firms or delivery services such as UPS and FedEx as suppliers of services that could impact an organization’s  ability to meet requirements, such as on time delivery and the delivery of product in an acceptable condition to the customer.

Most registrars welcome rebuttals from their clients regarding audit findings.  This could be an excellent opportunity for your company state its position to the registrar and to understand their rationale as to why they believe UPS and FedEx must be on the approved suppliers list.

The bottom line is that your registrar determines how its auditors interpret audit criteria such as clause 7.4.1.

If it is decided to add these companies to the approved supplier list, it should be a painless process since your company probably already has an established performance history for them.

I hope this helps!
