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
