To use FMEA to prevent breakdowns, you need to follow a structured process that consists of four main steps. First, you must define the scope and objectives of the FMEA by identifying the process, product, or system to be analyzed, its functions, requirements, and boundaries. Additionally, criteria and scales for rating the severity, occurrence, and detection of failure modes must be defined. Second, you should conduct the FMEA by brainstorming and documenting potential failure modes of each component or step, their causes, effects, and current controls. Rating the severity, occurrence, and detection of each failure mode and calculating the RPN should also be done. Afterwards, sorting the failure modes by RPN can help identify critical ones that need immediate attention. Thirdly, corrective actions should be implemented for each critical failure mode by developing and executing an action plan to reduce or eliminate the risk of failure. Assigning responsibilities, resources, and deadlines for the actions must also be done. Finally, review and update the FMEA by monitoring and measuring the effectiveness of corrective actions and their impact on the RPN. The FMEA should also be updated as needed to reflect changes in the process, product or system. Additionally, it should be reviewed periodically to ensure its validity and relevance.
