Understanding how to prioritize risk for corrective actions in an FMEA

Understanding how to prioritize risk for corrective actions in an FMEA

Prioritizing risk for corrective actions in an FMEA – Know before you go!

Note from author:

Since this article was originally published, there are subsequent articles in the “Inside FMEA” series that further describe better approaches than RPN to risk prioritization. Here are links:

Is There a Better Way Than RPN?

Risk Prioritization in FMEA – a Summary

Is There a Better Way Than RPN?

Text of the original article:

One of the most important steps in FMEA procedure is prioritizing risk for corrective actions. As soon as Severity, Occurrence, and Detection ratings have been determined for each failure mode and associated cause, the next step in an FMEA is to prioritize the risk and identify which issues need corrective actions. This step has been misapplied more often than any other step in the FMEA process.

FMEA Q and A – addressing errant cleaning operation in Process FMEA

FMEA Q and A

What if a production worker uses a different cleaning method for an assembly operation than was outlined in the operation work instructions, and the result is customer complaints and field issues. How could this be addressed in a Process FMEA? This question is discussed and answered in this FMEA Q and A article.

FMEA Q and A – Special Characteristics in Process FMEA

FMEA Q and A – Special Characteristics in Process FMEA

FMEA Q and A

Ponder this question: Let’s say you are an OEM and assemble parts made by various suppliers. When performing your Process FMEA, do you consider special characteristics for components in your Process FMEA? This question is discussed and answered in this edition of FMEA Q and A.

“The key to wisdom is this – constant and frequent questioning, for by doubting we are led to question, by questioning we arrive at the truth.”

Note from “Inside FMEA” Author

As of the date of this note, the Inside FMEA series of articles has completed the “Introduction to FMEA Series,” and is nearly complete with the “FMEA Fundamentals Series.”

This year, Inside FMEA articles will continue on a monthly basis. Each article will be posted for readers on the 1st day of the month.

As soon as the “FMEA Fundamentals Series” is completed, articles will continue with the “FMEA Preparation Series,” followed by the “FMEA Facilitation Series” and the “FMEA Special Topics Series.”

Readers of my book, Effective FMEAs, will continue to find the content of the Inside FMEA articles consistent with the concepts in the book.

It is my sincere desire that each and every person who reads Inside FMEA articles will discover the articles enjoyable to read and experience improved success in FMEA applications. As I say to readers of my book, “best wishes for effective FMEAs.”
