Till skillnad mot PFMEA, där man studerar olika processteg, utgår man i en DFMEA från de olika komponenterna (eller sub-funktionerna) i en design och uppskattar fel och risker för dessa. FMEA Scales for Severity, Occurrence & Detection Severity Scale for Failure Modes & Effects (s cale of 1 [least severe] to 10 [most severe] for each effect) Occurrence Scale for Potential Root Causes (s cale of 1 [least frequent] to 10 [most frequent] for each root cause) PROCESS FMEA (PFMEA) •The Process FMEA is normally used to analyze manufacturing and assembly processes at the system, subsystem or component levels.

DFMEA is a methodical approach used for identifying potential risks introduced in a new or changed design of a product/service. The Design FMEA initially identifies design functions, failure modes and their effects on the customer with corresponding severity ranking / danger of the effect.

Main drive is to understand the process through the identification of as many potential failuresas possible. o e.g. Incorrect material used z PFMEA typically assumes that the design is sound. z Development of Recommended Actions is targeted at eliminating the Root •DFMEA is a team effort •DFMEA process promotes actionable input to the design phase •Enables suppliers to add value and influence designs by highlighting functional concerns earlier in the design/development process •The risk of some failure modes will be associated with: – Supplier process capabilities – Material or finish selection Section 3 - Design FMEA (DFMEA) 3-1 Section 4 - Process FMEA (PFMEA) 4-1 Section 5 - Concept FMEA (CFMEA) 5-1 Section 6 - Special Characteristics 6-1 Appendix A - FMEA Forms A-1 Appendix B - Helpful Tools for FMEA B-1 Appendix C - FMEA Checklist C-1 Appendix D - Ford Automotive Procedures (FAPs) D-1 Appendix E - FMEA Applications E-1 Differences between DFMEA and PFMEA – Image source If you are a manufacturing organization that strives for continuous improvement and relies on concepts like six sigma and TPM, DFMEA and PFMEA can be used as a regular add-on for making incremental improvements to existing products and processes.
