AIAG's FMEA 4th Edition
The Chrysler, Ford and GM's Supplier Requirements Task Force has just released the
long anticipated, and occasionally dreaded, new edition of the Failure Mode Effects
Analysis (FMEA) Reference Manual.
The new edition has been anticipated since many users have lamented that the existing
manual only dealt with "filling out the form" and did not provide adequate
direction on the whole FMEA process and its relationship to other APQP activities
and information. Many individuals are concerned that the new manual will increase
their workload by changing and adding to the requirements they already have.
Don't be left in the dark when the new requirements become mandatory.
All our FMEA-related courses such as Manufacturing Process Development using PFMEA,
APQP & DFMEA including Robust Design Linkages, FMEA/Control Plan including Robust
Design Linkages and Advanced Product Quality Planning also incorporate the FMEA
Why FMEA Fourth Edition?
- FMEA is a process not a document
- Previous version focused primarily on the completion of the FMEA form and not on
the knowledge contained therein
- Management is an integral part of this process
- Minimize or eliminate column shifting
- Placing information in the wrong columns thus hindering the analysis and product
/ process improvement efforts
- Minimize or eliminate sole reliance on the RPN in the evaluation of risk priorities
and improvement actions
- Practice of deflating of the RPN to meet an arbitrary threshold
- Lack of understanding of the role of the FMEA process throughout the APQP phases
- Including continual improvement during production; i.e., looking at the FMEA as
a static document necessary only for PPAP approval
Improvements in the FMEA Reference Document
- Changes in format
- Additional examples
- Identification of the need for, and types of, Management Support
- Linkage Between DFMEA and PFMEA
- Changes to Risk Ranking Tables.
- Alternative Methods to Reduce Design Risk.
- Reduced Emphasis on RPN
- Consistent FMEA approach in Chapters 3 (Design) and 4 (Process)
