Failure Mode Effect Analysis (FMEA) is an essential proactive tool used to anticipate possible failures in processes, products, or services. It is recommended that a cross-functional team, including experts from design, maintenance, process, quality, and service domains work together to conduct FMEA, ensuring customer needs are met. FMEA should be carried out during the design or redesign phase, after quality function deployment, when implementing a process/product/service in a new way, before developing control plans, when setting improvement goals for an existing process, and periodically throughout the life of the process. To conduct FMEA effectively, assemble a diverse team with knowledge of the system/process, and identify all potential failure modes at the lowest maintainable item/function level. Consider the process, equipment, system, or design at an appropriate level to identify failure modes, focusing on physical phenomena rather than effects. Define the effects of each failure mode to understand the consequences on the system, assigning severity ratings on a scale of 1 to 10. Additionally, list potential causes for each failure mode, rate them for occurrence, and define current control measures (detection). Calculate the Risk Priority Number (RPN) by multiplying severity, occurrence, and detection ratings. Determine criticality using the formula Severity x Occurrence. Prioritize corrective actions based on RPN and criticality, identifying, planning, and executing countermeasures such as design or process changes. Assign responsibility and set target dates for countermeasure implementation in the FMEA. Review the implementation process for timeliness and effectiveness, recalculating RPN after countermeasures are in place. FMEA is a continuous revision process, with frequencies varying depending on the organization's needs. Set realistic targets for RPN reduction, considering cost and impact economics during evaluation.
Can you suggest a recommended product or reference for libraries of FMEA for rotating machinery that I can purchase or consult?
Shurafa asked for recommendations on a specific product or reference for libraries of Failure Mode and Effects Analysis (FMEA) for rotating equipment, such as pumps and fans. It is important to specify your requirements in order to receive tailored suggestions, as failure modes vary depending on the type of equipment and the operating conditions. Please provide more detail on your specific needs.
It is important to consider the variety of options available and narrow down the choices to find the most suitable solution for my specific needs. Let's examine centrifugal pumps and compressors, which are common choices for industrial settings such as power generation, chemical processing, and oil and gas production.
For a comprehensive guide on FMEA, be sure to check out the detailed breakdown provided in this article.
I completely agree with your comprehensive view on FMEA, especially about involving a cross-functional team. This ensures that all possible perspectives are taken into account, increasing the efficiency of identifying potential failure modes. Just to add, it might be beneficial to involve suppliers and customers in the process too. Suppliers can contribute valuable insights on raw materials related failure modes, contributing to the robustness of the analysis, while customers can provide unique perspectives on potential functionality and usability issues that internal teams might overlook. But definitely, a systematic yet dynamic application of FMEA throughout the lifecycle can do wonders for process improvement and risk mitigation.
