Timing for Closing High FMEA RPN Items

After completing a FMEA we get a whole list of items with high RPN values greater than 100. Anything over 100 I consider need to be addressed. I start by putting a reasonable date for completion, but I keep having to push date out further and further, because items are not getting completed on time. I even had to create my own tracking mechanism because of so many action items documented.

I am not aware of any timing requirement for closing items with high RPN values, but I wanted to ask if pushing items out, say 1 year from now or even 2, could cause issues for me down the road, say in TS or customer audits.

Welcome to the Cove! I apologize for the delay in responding.

To my knowledge, there is no express timeframe requirement for addressing FMEA items with high RPNs. I however know that IATF and customers are interested in addressing items with high severity levels, even if their overall RPN score does not rank them highest.

Yep, ever since they came up with the stupid RPN and said don't use it to prioritize actions, what does everyone do? They use it to prioritize actions. I'm with Jen, severity is the more applicable focus.

This whole misapplication of RPN is clearly explained in the AIAG FMEA Manual on page 57 (dFMEA) and page 103 (pFMEA).

Initial root cause analysis should start with those failure modes that have a high severity ranking. The best opportunity to make a process more robust is to look at occurrence. This requires true preventive actions to be implemented.

Enjoy studying the AIAG FMEA Manual. :agree1:

Yes it is. But reading is a skill. :) And most people are lazy - just start with the high number, no thinking required.
