Fmea Manual 4th Edition Changes
Fourth Edition ChangesFourth edition released in June 2008 An index is included. Glossary removed Reinforcement of the need for management support, interest, and review of the FMEA process and results. Define and strengthen the understanding of the linkage between DFMEA and PFMEA as well as defining the linkages to other tools. Revisions to the Severity, Occurrence, Detection ranking tables so that they are more meaningful to real world analysis and usage The suggestion that RPN not be used as the primary means for assessing risk.
The use of thresholds on RPN is clarified as a practice that is not recommended. Alternative methods to RPN are introduced that are currently being applied in industry like SO/SOD/SD Additional appendices which have example forms and special case application of FMEA.
The focus on the 'standard form' has been replaced with several options that represent the current application of FMEA in industry. Regards K S Varadhan. A couple quick notes on the 4th Edition- RPN levels- They don't want a 'set rpn level' to drive improvement ex.: everything over 100 rpn requires improvement. But RPN still matters. RPN = Sev X Occ x Det. They've also stated to try to use other methods to drive improvement. Other methods are Sev x Occ, or Sev x Det.
Some automotives already have 'rpn' levels for these SO-SD ratings in their specific requirements. Occurrence ratings- In light of this AIAG 'bumped up' all the occurrence requirements at least one level: 7 to 10 is still the same; but, 1 to 6 is changed. Before #6 Occ was 5pcs.
In 1000; now, in the 4thEd. In 1000 (this is a change from 5000ppm to 2000ppm).
This rate killing continues through the rest of the levels to #1, where failure is eliminated, not even 1ppm. I don't think they want 1's to mean anything. Aside- In every new edition of the fmea manual they have altered the ratings tables, supposedly for clarity??? The 4th Edition is no exception. Ratings continue to be re-defined so they are harder to meet.

We'll spend months re-defining our ratings and figuring out how to update our 200+ older version active fmea's to meet the living document clause. DFMEA linkage- 4th Ed. Linkage to the dfmea may mean that severity from the dfmea has to carry over to that item on the pfmea. We've seen too many customer dfmea's where every single item had severity of 7 or 8; now, we'll have to carry their severity over to the pfmea even though the rating is way out of line. Customer SQE's and SRE's will have a field day auditing the 4th Edition fmea's.
AIAG has to stay in business.
A draft of the AIAG-VDA FMEA Handbook was released in November 2017. It is clear that the 2018 changes to s for the automotive sector are BIG! The handbook represents the culmination of a three year project completely revising the AIAG FMEA Manual, a collaboration between OEMs and Tier 1 supplier members of the Automotive Industry Action Group (AIAG) and Verband der Automobilindustrie (VDA), Germany’s association for automotive manufacturers and suppliers. The result will be one common foundation for FMEAs across the global automotive sectors represented by AIAG and VDA. The new (draft) AIAG FMEA Manual provides more direction and specificity as to how FMEAs are to be conducted. Rumors about the RPN going away are true; the RPN is being replaced by the AP or Action Priority. That we highlighted in a blog post on FMEA-Training.com.
Thousands of people and hundreds of companies have trusted QualityTrainingPortal to learn and implement FMEAs and we will be there to guide you into the next phase of FMEAs. We have started working on series of new FMEA courses based on the proposed AIAG-VDA FMEA Alignment Handbook. While the changes can seem daunting, we are happy to report that everyday we get more comfortable with the draft version of the new handbook.
In fact, many of the improvements in the Handbook have always been a part of how we teach companies to do FMEAs! Plans for existing and future FMEA online training. Because these changes will only be required for the automotive sector, we plan to keep all of our existing “classic” FMEA courses active and available.
We will offer at least three new FMEA courses that are in line with the AIAG-VDA 2018 changes to FMEAs: AIAG-VDA Process FMEAs, AIAG-VDA Design FMEAs and AIAG-VDA FMEA-MSRs. These courses will not be available until after the final version of the 2018 AIAG-VDA FMEA Handbook is released.

We know that most people don’t have a day (or more realistically days) to sit down and digest the entire new handbook.
But, if you give us 5-10 minutes a week, we will give you a succinct analysis of the key changes to the 2018 AIAG FMEA Manual in 12 easy to consume weekly issues.
