This Month's Theme is Legal Guidelines for FMEAs
Next month's theme will be "how to get better results with FMEAs, in less time"
Every month in FMEA Corner, join Carl Carlson, a noted expert in the field of FMEAs and facilitation, as he addresses a different FMEA theme (based on his book Effective FMEAs) and also answers your questions.
Questions and answers are a great way to learn about FMEAs, for both experienced and less experienced FMEA practitioners. Please feel free to ask any question about any aspect of FMEAs. Send your questions to Carl.Carlson@EffectiveFMEAs.com, and your contact information will be kept anonymous. All questions will be answered, even if they are not featured in the FMEA Corner.
"Wisdom consists of the anticipation of consequences." - Norman Cousins
le·gal [le-gal, adjective]
The Oxford English Dictionary defines "legal" as "relating to the law." The word "law" is defined as "the system of rules which a particular country or community recognizes as regulating the actions of its members and which it may enforce by the imposition of penalties."
guide·line [gid-lin, noun]
The Oxford English Dictionary defines "guideline" as "a general rule, principle, or piece of advice."
What legal guidelines should be followed when doing FMEAs?
The following is an excerpt from chapter 5 of Effective FMEAs:
Can you anticipate everything?
In the words of Niels Bohr, "Prediction is very difficult, especially if it's about the future."
Consider this question: In an FMEA, is it possible to think of everything that might happen in the future?
FMEAs are intended to anticipate potential risk and develop actions that will reduce risk to acceptable levels. However, as pointed out in an article written by Daniel Simons entitled "You Can’t Anticipate Everything,"  there is a danger in over confidence.
In theory, a properly constituted FMEA team using proper FMEA procedure should be able to anticipate problems and recommend design or test improvements to reduce risk to an acceptable level. However, it is not impossible for something to be missed. This is why it is a good practice for FMEA to be performed as part of a comprehensive reliability program.
This subject is further discussed in FMEA Corner Issue 185 "Can You Anticipate Everything?"
Scenarios involving FMEAs, including potential legal consequences
The following is excerpted from a paper presented by Carl Carlson and Jeffrey Patterson to the American Bar Association in Phoenix, Arizona in April 2016, titled "FMEA: How to do it right and the litigation consequences of doing it wrong." 
Consider using the FMEA quality objectives when asking the question, "Was the FMEA done properly?" The FMEA Corner article in HotWire issue 180 "Common FMEA Mistakes" discusses the most common FMEA mistakes and the corresponding quality objectives.
I’ve always wanted to know about FMEAs
The important thing is not to stop questioning. - Albert Einstein
A reader submitted the following question to Carl Carlson. To submit your own question about any aspect of FMEA theory or application, e-mail Carl at Carl.Carlson@EffectiveFMEAs.com.
I would like to enquire about failure mode libraries.
The company I work for deals with companies in many industries, and I would like to be able to compare failure modes, and perhaps failure rates between pumps across multiple industries, as an example.
Thank you in advance for taking the time to read this email.
Carl: Thanks for the question.
I'll begin my reply with a quote from chapter 5 of my book.
There are publications with selected generic failure modes. In addition to the one you mentioned, I'm aware of these: 1. The book Failure of Materials in Mechanical Design: Analysis, Prediction, Prevention, by Jack Collins, lists typical failure mechanisms; and 2. Alion System Reliability Center offers a publication "Failure Mode/Mechanism Distributions" which is a compendium of failure mode and mechanism data, including relative probabilities of occurrence.
As you can see from the excerpt from my book, I advise caution when using generic failure modes. They can be helpful, under limited circumstances.
Good luck in your application.
