Think about the three ually ANY failure mode with a Severity of 5 or higher automatically gets attention. Never stop pursuing the ability to reduce the RPN's. There will always be a failure mode(s) with a higher score than others. The process never stops in the world of quality control. The idea is to go after the highest RPN on a regular basis. This is obviously a significant improvement but it may not be enough depending on the customer needs. Therefore, the RPN for that failure mode was reduced from 135 to 40. What is the RPN for the Revised FMEA? The answer is 5*2*4 = 40 Severity = 5 (usually the severity of the failure mode stays the same but not always) Therefore, the revised FMEA now has the following scores assigned by the team: Next, assume the team implemented a few poka-yokes and other improvements. RPN = Severity * Detection * Occurrence = 5 * 3 * 9 = 135 Severity = 5, Detection = 3, and Occurrence = 9 What is the Risk Priority Number (RPN) of a particular failure mode where the team assigned the following values? Share Facebook Twitter WhatsApp Example Test Questions FMEA TemplateĬlick here to purchase the FMEA and REVISED FMEA template. Recommended to become very familiar with this tool and how it works. They are used for design, processes, services, and more. This tool is widely used in quality control organizations acrossĪll industries and segments to improve customer satisfaction. Often times an improvement can be applied to other Complete any easy improvement actions regardless of RPN.Īn improvement is done, rescore the failure mode and continue on the journey of.On reducing the Severity, Occurrence, and Detection. The Failure Modes in descending order with the highest RPN’s at the top. It’s a never-ending cycle and not all of the failure modes have to be Revised FMEA (used in CONTROL phase) (complete the yellow highlighted section - use original FMEA) CLICK HERE to get this FMEA Template Therefore, to make the list on the FMEA as a Failure Mode, there must be a score >0 assigned to each the Severity, Occurrence, and Detection score. Keep in mind, none of the scores can be a zero or the RPN will be zero. As improvements are completed, revised values are determined by the team and entered on the same original FMEA and this becomes the REVISED FMEA (see the YELLOW portion of the figure below). This activity becomes part of the IMPROVE phase (sometimes it's done in the CONTROL phase). ![]() The team may choose to try all of them or just a fewĭepending on the magnitude, time allotted for the project, and other
