Supplier Quality Assurance:

Confidence a supplier’s product or service will fulfill its customers’ needs. This confidence is achieved by creating a relationship between the customer and supplier that ensures the product will be fit for use with minimal corrective action and inspection.

7. Certify qualified suppliers;
8. Conduct quality improvement programs as required;
9. Create and use supplier quality ratings.
