    Does anyone have examples of custom Severity, Occurrence and Detection tables for use on machined components? There's no way that (in general) drilling a hole too deep will kill someone, so what ranking criteria get used? Examples please!

    These are more generic, but may be useful.

    Thanks, Miner. These may well do the trick!

    This is certainly one area where the AIAG/VDA harmonization team got it right. Specifically in regard to the "occurrence" table. 4th edition and prior "occurrence" rating tables (as written) were not necessarily appropriate for bulk or other non-typical volume/frequency occurrences.
