FMEA (Failure Mode and Effects Analysis) – Method Description

Short Description

FMEA (Failure Mode and Effects Analysis) is a structured method used to identify potential failures, analyse their impact, and define actions to reduce risk in products and processes.

Key Information

Category Value
Area Quality Management / Risk Management
Type Preventive Method
Risk High
Effort High
Participants Cross-functional team (Engineering, Quality, Production)
Use Case Risk analysis, product development, process improvement

Purpose

The purpose of FMEA is to identify potential risks early, evaluate their impact, and implement actions to prevent failures before they occur.

It supports structured risk management, quality improvement, and reliability enhancement in product and process development.

 When to Use This Method

FMEA is typically used in the following situations:

  • During product development (DFMEA)
  • During process development (PFMEA)
  • Before production or product launch
  • When introducing design or process changes
  • For continuous improvement and risk reduction

Preconditions 

Before applying FMEA, the following should be available:

  • Clear definition of product, system, or process
  • Basic understanding of functions and requirements
  • Cross-functional team with relevant expertise
  • Available data on previous failures

How to Apply This Method?

Define The Scope
Identify the system, product, or process to be analyzed

Identify Functions and Requirements
Understand what the system or process is expected to do

Identify Potential Failure Modes
Determine how the system or process can fail

Analyze Effects Of Failures
Evaluate the impact of each failure

Identify Causes Of Failures
Determine root causes for each failure mode

Assess Risk (Severity, Occurrence, Detection)
Evaluate the risk level using structured criteria

Define Corrective Actions
Implement actions to reduce or eliminate risks

Review And Update
Continuously update the FMEA based on new data

Tips For Effective Use

  • Use a cross-functional team
  • Focus on real risks, not theory
  • Keep scoring consistent
  • Start early in development
  • Review and update regularly

Outputs                   

  • Identified failure modes and risks
  • Risk prioritization (Severity, Occurrence, Detection)
  • Defined corrective actions
  • Updated FMEA document

Example

Scenario: Assembly process in manufacturing

  • Failure Mode: Incorrect component installation
  • Effect: Product malfunction
  • Cause: Lack of clear work instruction
  • Action: Improve work instructions and operator training
