4.1.2. Performance Step

In the FMEA performance step, the causes, effects, countermeasures, and severity for each failure mode were discussed; these items were recorded and organized through a worksheet [4]. Here, the effect of the failure mode could be confirmed through the experience of the evaluator, drawings, or simulations. The RPN was used in the evaluation, which indicates the S, O, and D when performing FMEA [5].
