A DFMEA (Design Failure Mode and Effects Analysis) is a systematic approach to identifying potential failure modes and their associated causes and effects in a design or process. It is used to identify and prioritize potential design or process failures that could lead to customer dissatisfaction, injury, or even death. The goal of a DFMEA is to identify and reduce the risks associated with these potential failures. The process begins with a thorough analysis of the design or process, followed by the identification of potential failure modes and their associated causes and effects. The analysis then proceeds to determine the severity, occurrence, and detection of each failure mode. Finally, the analysis provides a means of prioritizing the failure modes and their associated risks, allowing the design or process to be improved to reduce the risk of failure. A DFMEA is an important tool for ensuring the safety and reliability of a design or process, and is an essential part of any successful quality assurance program.
