In the world of Quality, what is the importance of using "Failure modes and effects analysis:?

I think Mr Ayoub Tartir are quoting Wikipedia

"Failure Mode and Effects Analysis (FMEA) was one of the first systematic techniques for failure analysis. It was developed by reliability engineers in the1950s to study problems that might arise from malfunctions of military systems.

An FMEA is often the first step of a system reliability study. It involves reviewing as many components, assemblies, and subsystems a possible to identify failure modes, and their causes and effects.  

FMEA is mainly a qualitative analysis.

• Functional,
• Design, and
• Process FMEA.

Sometimes FMEA is extended to FMECA to indicate that criticality analysis is performed too.

FMEA is an inductive reasoning (forward logic) single point of failure analysis and is a core task in reliability engineering, safety engineering and quality engineering. Quality engineering is specially concerned with the "Process" (Manufacturing and Assembly) type of FMEA.

A successful FMEA activity helps to identify potential failure modes based on experience with similar products and processes - or based on common physics of failure logic. It is widely used in development and manufacturing industries in various phases of the product life cycle. Effects analysis refers to studying the consequences of those failures on different system levels.

Functional analyses are needed as an input to determine correct failure modes, at all system levels, both for functional FMEA or Piece-Part (hardware) FMEA. An FMEA is used to structure Mitigation for Risk reduction based on either failure (mode) effect severity reduction or based on lowering the probability of failure or both. The FMEA is in principle a full inductive (forward logic) analysis, however the failure probability can only be estimated or reduced by understanding the failure mechanism. Ideally this probability shall be lowered to "impossible to occur" by eliminating the (root) causes. It is therefore important to include in the FMEA an appropriate depth of information on the causes of failure (deductive analysis)"

FMEA is the first step of a system reliability study. It involves reviewing as many components, assemblies, and subsystems as possible to identify failure modes, and their causes and effects

I agree with the elegant answers of Mr.  جعفر هندي زين السقاف  and Miss. Elke Woofter.

They have given all the needed information.

Thanks for all!

Failure modes and effects analysis -

Also called: potential failure modes and effects analysis; failure modes, effects and criticality analysis (FMECA).

Failure modes and effects analysis (FMEA) is a step-by-step approach for identifying all possible failures in a design, a manufacturing or assembly process, or a product or service.

“Failure modes” means the ways, or modes, in which something might fail. Failures are any errors or defects, especially ones that affect the customer, and can be potential or actual.

“Effects analysis” refers to studying the consequences of those failures.

Failures are prioritized according to how serious their consequences are, how frequently they occur and how easily they can be detected. The purpose of the FMEA is to take actions to eliminate or reduce failures, starting with the highest-priority ones.

Failure modes and effects analysis also documents current knowledge and actions about the risks of failures, for use in continuous improvement. FMEA is used during design to prevent failures. Later it’s used for control, before and during ongoing operation of the process. Ideally, FMEA begins during the earliest conceptual stages of design and continues throughout the life of the product or service.

Begun in the1940s by the U.S. military, FMEA was further developed by the aerospace and automotive industries. Several industries maintain formal FMEA standards.

What follows is an overview and reference. Before undertaking an FMEA process, learn more about standards and specific methods in your organization and industry through other references and training.

• When a process, product or service is being designed or redesigned, after quality function deployment.
• 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 analyzing failures of an existing process, product or service.
• Periodically throughout the life of the process, product or service

Thanks for the invitation

Good question

Agreed with the excellent description  given

by Mss.: Elke Woofter 

I agree with the answer of Richa Verma.

Hello,

FMEA is a proactive tools to ensure quality, which ensures all the processes from Incoming to Final Dispatch.

In this tool, we can capture Failure Mode and impact of the same.

And later on it is used to prevent those failure mode with a proper action plan being in place.

I agree with the answers above specially "Elke Woofter "

FMEA if it is well implemented should provide the Management with better comprehension of a the organisation's processes then the most thinked preventative actions are undertaken 

FMEA is by excellence a preventative tool for quality enhancement

I agree with the elegant answers of Mr.Ga3gar
