FMEA (Failure Mode and Effects Analysis)

Failure Mode and Effects Analysis (FMEA) is a structured approach to discovering potential errors that may exist in the design of a product or process.

FMEA has two broad categories: Design FMEA (DFMEA) and Process FMEA (PFMEA).

Design FMEA

Design FMEA (DFMEA) investigates the possibility of product failures, shortening of product life, and safety and regulatory concerns arising from:

–Material properties

– Geometry

– Tolerances

– Interfaces with other components and/or systems

Process FMEA

Process FMEA (PFMEA) discovers failures that affect product quality, process reliability, customer dissatisfaction, and safety or environmental hazards caused by:

–Human factors

– Methods followed during processing

– Materials Used

–Machines Used

– Effects of measuring systems on acceptance

– Environmental Factors on process performance
