Are you asking whether the in-process 'quality' audit should be included as an item in the PFMEA?
If so, quality audits are typically looked at as one of the controls for the other process items. If there is some chance that the audit could have a detrimental impact on the quality, include it. Otherwise, the only failure modes typically associated with inspection are:
- Reject a good product
- Accept a bad product
- Fail to follow procedure for nonconforming product
