Definition of FMEA

A FMEA is an analytical tool that uses a

disciplined technique to identify and help

eliminate product and process potential

failure modes.

By ID of potential failures

Assessing the risks caused by failure modes and

Identify corrective actions

Prioritizing corrective actions

Carry out corrective actions

Most COMMON Types of FMEA's

Design (Potential) Failure Modes and

Effects Analysis-DFMEA

? Focus is on potential design- related failures

and their causes.

Process (Potential) Failures Modes and

Effects Analysis-PFMEA

? Focuses is on potential process failures and

their causes.
