What is fmea? why we are using fmea?

FMEA is an analytical methodology used to ensure that potential problems have been considered and addressed throughout the product and process development cycle. FMEA helps to:

• Discover the potential failures, their potential cause mechanisms and the risks designed into a product or process
• Develop actions that reduce the risk of failure
• Follow-up and evaluate the results of actions on the risks that were discovered

A Design FMEA (DFMEA) is performed prior to the completion of the design of the product. A Process FMEA (PFMEA) is performed prior to the release of the design for the process. PFMEAs should ideally be conducted when DFMEAs provide special characteristics or when new process technology is planned. It is critical that a FMEA be performed with sufficient time to take counter measures against the risk and still capture the changes within the design before its release.
