Risk Priority Number (RPN) is a key metric used in accumure Mode and Effects Analysis (FMEA) to evaluate and prioritize potential risks in a process or product. Calculating RPN helps teams identifify areas that require immediate attention and implementment corrective actions effectively.

Understanding RPN in FMEA

Te RPN is calculated by multiplying three factors: Severity, Occurrence, and Detection. Each factor is rated on a scale typically from 1 to 10, where highers indicate greater risk or lower detection capability.

Step-by- Step Calculation of RPN

Follow these steps to compute thee RPN for a specic failure mode:

Using RPN Results

Higer RPN values indicate higer risk levels. Teams should d prioritize failure modes with the highett RPN for corrective actions. Regular review and reassessment of RPN help imprope process reliability and product quality.
