What is failure modes and effects analysis?
Identify ways the product or process can fail
Plan how to prevent those failures
How Does FMEA Work?
Identify potential failure modes and rate the severity of their effect
Evaluate objectively the probability of occurrence of causes and the ability to detect the cause when it occurs
Rank order potential product and process deficiencies
Focus on eliminating product and process concerns and help prevent problems from occurring
FMEA Links Cause

Definition - FMEA
A structured approach to:
identifying the ways in which a process can fail to meet critical customer requirements
estimating the risk of specific causes with regard to these failures
evaluating the current control plan for preventing these failures from occurring
prioritizing the actions that should be taken to improve the process
Identify ways the product or process can fail. Then plan to prevent those failures.
Purposes & Benefits of FMEA
Improves the quality, reliability, and safety of products.
Helps to increase customer satisfaction.
Reduces product development timing and cost.
Documents and tracks actions taken to reduce risk.
Types of FMEA
System FMEA: is used to analyze systems and subsystems in the early concept and design stages. Focuses on potential failure modes associated with the functions of a system caused by design.
Design FMEA: is used to analyze products before they are released to production.
Process FMEA: is used to analyze manufacturing, assembly and transactional processes.
