Created page with "== What is FMEA and when is it used? == FMEA is a step by step approach for collecting knowledge about possible points of failure in a design, manufacturing or construction proc..."

New page

== What is FMEA and when is it used? ==

FMEA is a step by step approach for collecting knowledge about possible points of failure in a design, manufacturing or construction process, product or service:

* When a process, product or service is being designed or redesigned
* When an existing process, product or service is being applied in a new way
* Before developing control plans for a new or modified process
* When improvement goals are planned for an existing process, product or service
* When analysing failures of an existing process, product or service
* Periodically throughout the life of the process, product or service.

American Society for Quality (ASQ) 2017

== History of FMEA ==

FMEA was first used by the US navy in 1949 to understand and control the risks in their procedures, including operation of weapon systems. It was also used in the 1960’s for the Apollo missions and then from the 1970’s by the automotive industry.

== Use of FMEA in the Project Lifecycle ==

It can be used by Project Teams to assess and control how a process or item can fail for example:

* Design – To check the feasibility of design prior to build
* Material – To ensure correct selection of material prior to build
* Construction – To understand risks in assembly prior to build
* Commissioning – To understand potential operational failures prior to use
* Changes to Plan – The potential risks resulting from having to change a process or an item

== Benefits ==

* Captures collective knowledge of team
* Improves quality, reliability and safety of the process
* Logical structured process identifying areas of concern
* Reduces development time and cost
* Quality led activity

=== Step 1: Setup ===

|}

=== Step 2: Consider potential failures (for each critical item / process list the potential points of failure) ===

{|

|width="100%"| Observation: Potential failure mode(s)
|-
| Concrete not curing

Failure Mode

* How can the item or process fail?
* E.g. fatigue, cracking, deformation….

Effect of failure

* Impact of failure on the operation, function or functionality
* May affect customer, general public, workforce, business & environment etc.

Cause of failure

* What has caused the failure to occur
* Important to understand the ‘root’ cause.
|
{|
|width="100%"| Current process controls
|-
| No control
|-
| Cube tests
|}

Current controls

* Controls & tests that are already in place which may highlight failures that occur
|}

=== Step 3: Assessment of failure ===

{|
|width="50%"|
Occurrence (OCC)

* How frequent will the failure happen
* Probability of occurrence
* Higher number more likely to occur
|width="50%"|
Severity (SEV)

* Worst case scenario of impact if the failure occurred
* Higher number worse impact
|-
|
Detection (DET)

* Likelihood of the failure being detected with current controls
* Higher number less likely to detect
|
Risk Priority Number (RPN)

* RPN = OCC x SEV x DET
* Special attention should be given to high severity
|}

=== Step 4: Actions to be taken ===

{|
|width="33%"|
Corrective Actions

* Actions to reduce the RPN
* RPN should ideally be less than 25
|width="33%"|
Revised Assessment

* Completed actions should reduce occurrence, severity or improve detectability
* RPN updated accordingly
|width="33%"|
Post FMEA

* Regular review important to check assessment still valid and to pick up any changes that occur.
