4.6 Post Validation Audit- PVA (reference GMW3600 and GMW15758)
a. The GM SVE reserves the right to initiate a Post Validation Audit (PVA) including but not limited to the following conditions:
i. PVA shall be performed on selected components by using agreed upon validation procedures where the test results are very sensitive to manufacturing variation.
ii. Did not follow sample selection per GMW15760, where feasible.
iii. PVA shall be performed on a component that was marginal based on the learning rom past programs and/or during PV testing to meet Reliability and/or Performance requirements An example of a marginal result is a B1 life between 1 and 1.2 lives on fatigue test, then PVA testing is required.
iv. PVA shall be performed when NEW issues discovered during validation or confirmation testing at any build phase due to manufacturing process variation.
v. PVA shall be performed when noted in the VCRI driven by historical issues
b. The PVA Exit phase criteria, sample size, frequency and duration to be established by the SVE. Validation TIE, and GSSLT.
c. The sample selection must follow GMW15760 Multi-Vari Sample Selection Procedure for Product Validation.
d. The cost associated with PVA testing is the supplier’s responsibility.

e. If a requirement is not met during PVA testing, a PRTS or PRR shall be written

4.7 Regulatory Compliance Self-Certification Requirements

The Supplier shall complete their portion of the GM Self-Certification Compliance Summary Document(s) for the commodity as described by GMW3600, Sections 4.7.2 and 4.7.5, by 4 weeks prior to the VDC milestone.

The Supplier shall obtain the required Component and Subsystem Approvals for the commodity as described in GMW3600, Sections 4.7.3, 4.7.4 and 4.7.6, by 4 weeks prior to the VDC milestone.

Note: i. Regulatory compliance evaluation reports and documentation shall be complete and submitted to the Validation Engineer 4 weeks prior to the VDC milestone for any new model program.
ii. Regulatory compliance evaluation reports and documentation shall be complete and submitted to the Validation Engineer 10 weeks prior to the VDC milestone for any carry over model program.

5COMMODITY VALIDATION SIGN-OFF

In addition to the Commodity Validation Sign-off requirements specified in GMW3600 Section 5.4, the Supplier shall comply with the addition requirements listed below.
No additional sign-off requirements.
