8.4.3 Information for external providers

This requirement is again comparable to the requirements from ISO 9001:2008 Clause 7.4.2 – Purchasing Information. You should seek and record evidence that your organization has, where appropriate, communicated not just the products or services they wish to receive, but also any processes they want the external provider to undertake on their behalf, as well as any interactions with your organization’s management system. You should also check that the requirement for competency of external personnel is communicated.

ISO 9001:2015 requires that the purchasing documentation contains the correct information before it is issued to a supplier. This verification can be undertaken by the Procurement Manager. Describe the product to be purchased by:

  1. Defining product approval requirements, e.g. certificate of conformity;
  2. Defining intended verification arrangements, e.g. witness testing or certification;
  3. Defining personnel qualifications and quality and environmental requirements;
  4. Maintaining records.
