Transcript of Failure Mode and Effect Analysis

Failure Mode and Effect Analysis
Types of FMEA
• System
• Design
• Process <---
• Usage

How to create a FMEA?
1. FMEA Pre-Work
2. Failure Modes
3. Causes & Occurrences
4. Detection Methods
5. Action Priority & Assignment
6. Actions Taken / Design Review
7. Re-ranking RPN & Closure
What is FMEA?
Danny Mullinax
1949 - US Armed Forces
To classify failures “according to their impact on mission success and personnel/equipment safety.”
1980s - Automotive industry - Ford

Failure Mode
the ways, or modes, in which something might fail

Effects Analysis
studying of the consequences of those failures

1993 - Automotive Industry Action Group FMEA Handbook
Now widely used in a variety of industries including healthcare, food service, and software
Assemble a cross-functional team
Identify the scope
ie: system, design, process, etc
Fill out identifying information
Failure Modes
Identify the functions
Identify all the ways the function could fail
Identify the effects of each failure
Assign a Severity to each failure
1 = Low 10 = High
Causes and Occurrences
Determine possible root causes for each failure
Determine an occurrence rating for each failure
1 = Low 10 = High
Detection Methods
Identify current control methods
Determine a detection rating for each failure
1 = Always detected
10 = Remote possibility of detection
Action Priority & Assignment
Calculate Risk Priority Number
Severity * Occurrence * Detection
High RPN's could indicate where actions need to be taken
High RPN's should be evaluated for inflation
Ex: 3 * 8 * 2 vs 8 * 1 * 6
Actions Taken / Design
Identify recommended actions to reduce S and/or O and/or D
Re-ranking RPN & Closure
Note details of actions taken for re-evaluation
Determine new S, O, and D rankings based on actions
Repeat as necessary
