WebThe FMEA RPN does not cover all the numbers in the range from 1 to 1000. Therefore, some companies use the numerical value of SOD. In this case, the values of S, O, and D range from 0 to 9 (not from 1 to 10). Web原則上主導人員應為 fmea 推進者來完成此範例，撰寫人員可由產品研發人員、工程人員或研發品保人員等一起討論出一個合理的判定標準。 甚至有些客戶會直接提供供應商 S／O／D 判斷標準，由供應商直接執行。

WebOutputs. The main output from an FMEA is a Risk Priority Number (RPN) for each failure mode. The RPN is an objective priority measure for fixing any failure mode or failure mode effect. The bigger the RPN, the higher the priority. The formula for calculating an RPN is: RPN = Severity * Occurrence * Detection.
