A PFMEA (Process Failure Mode and Effects Analysis) is a structured approach to identifying potential problems and their associated causes and effects in a process. It is used to identify and prioritize areas for improvement and to document current process knowledge. The goal of a PFMEA is to identify and eliminate potential process failures before they occur. It is a systematic approach to understanding the risks associated with a process and taking steps to reduce or eliminate them. The PFMEA process begins with a thorough understanding of the process and its inputs and outputs. The process is then broken down into its individual steps and potential failure modes are identified. For each potential failure mode, the severity of the failure, the probability of occurrence, and the detectability of the failure are determined. Finally, corrective actions are identified and implemented to reduce or eliminate the potential failure modes. A PFMEA is an important tool for improving the quality of a process and can help to identify areas for improvement before problems occur.
