Linking Control Plans and PFMEA's

[TJ]

I am looking for evidence in the IATF standard or the AIAG handbook that tells me that my controls from my PFMEA need to happen in the same operation as they do in the control plan. Basically, I have identified all my failures from a certain operation step in my FMEA where the failure is actually occurring. I cannot check or detect those failures until later on in the process. I have called out the attribute gauging at a later stage in my control plan and not in the steps that the failures are created and listed in my PFMEA. Auditor thinks my control plan should be calling out the control during those steps and not when it is actually happening and is using "line for line" literally. I interpret the standards to be "line for line" meaning we control all lines in the FMEA at some point in the control plan. If not, what is the "detect post processing" for in relation to the detection on the FMEA. I need the evidence from the standard to help prove my case. Please and thank you

Good day @TJ ;
The question I believe you should be asking instead is...where is the requirement (implied/stated by the auditor) that the sequence/numbering on the control plan and those PFMEA must "match" ?

There is no such requirement. In fact, within the AIAG/VDA harmonized PFMEA approach, the AIAG has finally embraced/promotes family/foundation PFMEA. When such is applied, it is even more unlikely that the PFMEA and Control Plan sequence/numbering will match.

The INTENT of the PFMEA is to identify the potential failure modes and their risks.
The INTENT of the control plan is to identify (as the name implies) the process controls, including commensurate with the risks identified in the control plan.

If this is done, then your auditor needs to define the "problem" he or she is alluding to.

Hope this helps.
Be well.

In addition, you could always note in the FMEA that those controls take place at a later operation.

Hello,

I think as the Control plan must be in line with PFMEA , the product and process characteristic which are defined in the PFMEA must be in the control plan. For users by soft (APIS, IQS, etc) are more easily understand this requirement because the soft can be offer this opportunity. For Excel or other tools which are not have possibility link the PFMEA with Control Plan is difficulty for understand and put in practical. So, not all functions from PFMEA will be control (added ) I the Control plan, just product characteristic and process characteristic with Special characteristic where is case. The Control plan have the 3 parts (Incoming, Manufacturing and Monitoring & control).
