Recently, OEMs have identified in their IATF 16949 Customer Specific requirements, the need to Develop Reverse FMEAs. The purpose of the Reverse FMEA is to assure the customer that risks defined in the PFMEA are properly addressed and functioning as promised once the product goes into production. Even though the PFMEA is developed early in the production cycle, the verification of the effectiveness of identified controls is not always completed. This lack of verification may result in risk to the customer if the process design controls do not adequately provide the intended coverage. Additionally, potential issues may only become apparent after the product goes into production.
