Example of a simple FMEA Analysis Table

FMEA: Failure Mode and Effect Analysis

 

 

 

FMEA is for “Failure Mode and Effect Analysis

 

FMEA methodology was originally developed by the US Military in the late 1940’s as a method to improve the weapons and military systems, to analyze and avoid costly and fatal failures. Due to the simplicity and affectivity it has been almost generally adopted by companies around the world, as failure preventive or corrective  methodology and as a products and services improvement tool.  

 

This tool is a very useful in the course of designing, improving or finding failure modes on products and services were failures were not evident from the original design or manufacturing process. FMEA focuses on finding the real or potential causes for failures and the effects that these failures can or could induce.

 

FMEA Types

 

Many types of  FMEA exist, depending on their specific functional deployment, here are some of them:

 

1- Design. Involved on design of hardware, equipment and machines

2- Process. Involved on production and assembly

3- System. Involved on universal system functions

4- Services. Involved on Services functions

5- Software. Involved on software function and applications

 

FMEA Methodology

 

In General the FMEA analysis method involves these steps in this order:

 

1- Process, system or service under study definition

 

2- Potential failure mode analysis

 

3- Potential failures effects analysis, plus failure severity designation from 0 to 10, being 10     the most severe

 

4- Potential causes analysis, plus cause and effect occurrence designation from 0 to 10,     being 10 the most frequent

 

5- Currently used controls, what are the best controls and methods in hand to detect and control     the causes and failures, plus detection ability from 0 to 10,  being 10 the least detectable     failure mode

 

6- Determination of the RPN or Risk Priority Number = (Severity) X (Occurrence) X (Detection     ability)

 

7- Action recommended

 

8- Responsibility designation

 

9- Action taken, conclusions and recording

 

10- Reassessment and periodic improvement review
