All defects, nonconforming supplies, and instances of noncompliance with the warranty language of the contract must be reported and properly documented (in the contract file) by the CO. When the supplier has been qualified on the basis of quality management systems and defects subsequently become apparent, the purchase/SCM team should require review of the supplier’s QA documentation or processes. When discrepancies are apparent, this information should be taken under consideration for the (Reserved) topic of the Manage Delivery and Contract Performance task of USPS Supplying Practices Process Step 5: Measure and Manage Supply. Discrepancies should also be addressed during lessons learned discussions with the supplier described in Section 5-9, Share Lessons Learned.
