P
Appendix F of the PPAP manual specifies alternative rating scales for assessing 'non conformance' in bulk materials supplied which may be used to calculate the RPN and develop / review the process control plan.
The table for Occurrence Ratings refers to -
High - repeated failures
Moderate - occasional failures
Low - relatively few failures
These definitions are not quantified or related to the capability of the production process providing the bulk materials - so how would you interpret them?
Should they be referenced to a specified failure rate or level of process capability?
