Where are FMEAs (and their standards) Heading?
Abstract
Carl and Chris discussing the future of FMEA, sharing their vision for where FMEA as a method is headed, as well as where we think it should be headed.
Key Points
Join Carl and Chris as they discuss the standards and methodology of FMEA, and analyze the trends that impact its use and value.
- What are the trends that affect FMEAs:? Are they positive of negative?
- The two types of FMEA users
- Should you follow FMEA standards exactly, or can they be tailored to your application?
- Understanding the fundamentals of FMEA is essential to properly use FMEA standards
- The role of Corrective Actions in applying FMEAs
- Next generation of FMEA standard is SAE 1025
- Keep your eye on the ball: reduce risk to acceptable level
- We don’t need both acronyms FMEA and FMECA; both have a criticality analysis.
- FMEAs that are done early in the product development process are usually qualitative.
- Future is to use specific selection criteria to select when FMEA is used; preliminary risk assessment
- Future is to balance automation of selective portion of FMEAs, with team involvement on high-risk areas.
- Future is an integration of Model-Based Engineering with FMEA procedure

The big questions, how much risk is acceptable?
As long as we are on the planet thee will always be risk.
FMECA Vs FMEA (What is the Difference Between Them?)
The criticality analysis aspect of FMECA is performed post-FMEA. Where FMEA only offers qualitative information, FMECA offers both qualitative and quantitative information, allowing users to measure a level of criticality to failure modes and order them according to importance.
Failure modes, effects, and criticality analysis (FMECA) is a technique used to identify potential failures in systems and equipment. Once you have identified the failure modes, you can determine their effects and prioritize them based on how critical they are.- https://fiixsoftware.com/glossary/fmeca/#:~:text=Failure%20modes%2C%20effects%2C%20and%20criticality,on%20how%20critical%20they%20are.

Hello Carl,
Thanks for offering your comments on SOR 892. I’ll provide my thoughts in response to each of your comments, directly below.
You comment: “The big question, how much risk is acceptable? As long as we are on the planet there will always be risk.”
My thoughts: I fully agree. There will always be risk. As I mentioned In the SOR, the challenge is to keep our eye on the ball, and to reduce risk to an acceptable level. We cannot achieve zero risk. Regarding what level of risk is acceptable, it is very much company dependent, product dependent, mission dependent. Management has to provide guidelines, and stay actively involved with FMEA teams to ensure risk is acceptable to the company, the users, the mission. The focus of FMEA teams should be to properly assess and prioritize risk, and to recommend actions to reduce risk to acceptable levels, given the usage and operating environments.
You made the following statement about FMECA Vs FMEA (What is the Difference Between Them?)
“The criticality analysis aspect of FMECA is performed post-FMEA. Where FMEA only offers qualitative information, FMECA offers both qualitative and quantitative information, allowing users to measure a level of criticality to failure modes and order them according to importance.”
My input is to refer back to the article I wrote on this subject:
https://fred-schenkelberg-project.prev01.rmkr.net/fmea-or-fmeca-whats-the-difference/
In this article, I share my view that the overwhelming applications of FMEA and FMECA use some form of criticality analysis. In all automotive FMEA applications and for aerospace that uses SAE J1739:2021, FMEAs include risk prioritization that is similar to Mil-Std-1629A FMECA. And Mil-Std 1629A is being modernized to provide clarity to this subject.
You provided a link to a website that describes the different types of FMEA.
I would also add a reference to the FMEA Fundamentals articles in the Inside FMEA series.
https://fred-schenkelberg-project.prev01.rmkr.net/inside-fmea-index-articles/
These articles show the definitions and differences for each of the FMEA types: System FMEA, Design FMEA, Process FMEA, Software FMEA and Supportability FMEA.
Let me know if you have any other comments or questions.
Thanks.
Carl
Hi Guys.
Great discussion Carl and Chris.
I noticed at the beginning of the podcast that Carl mentioned key fundamentals that cannot be compromised when a company tailors a FMEA process or form. Later in the podcast Chris mentions that every standard encourages companies to tailor the process to meet their needs. I think a great future podcast discussion would be which parts of the process can and cannot be tailored and maybe some best practices about tailoring the process.
Thanks for all of your great advice in the past.
Bob
