Similar principles and steps are followed for both design and process FMEAs.
The primary objective of a Design-FMEA is to uncover potential failures associated with the product that could cause:
- Product malfunctions
- Shortened product life
- Safety hazards while using the product
Design-FMEAs should be used throughout the design process – from preliminary design until the product goes into production.
Process-FMEAs uncover potential failures that can:
- Impact product quality
- Reduce process reliability
- Cause customer dissatisfaction
- Create safety or environmental hazards
Ideally, Process-FMEAs should be conducted prior to start-up of a new process, but they can be conducted on existing processes as well.
