From the information given below, identify the failure mode, which has the highest risk involved.
From the information given below, identify the failure mode, which has the highest risk involved.
To determine the failure mode with the highest risk, we calculate the Risk Priority Number (RPN) for each failure mode by multiplying the Severity, Occurrence, and Detection values. The RPN for each failure mode is as follows: Failure mode 1: 8 * 2 * 2 = 32 Failure mode 2: 8 * 4 * 4 = 128 Failure mode 3: 10 * 3 * 3 = 90 Failure mode 4: 9 * 2 * 4 = 72 Among these, Failure mode 2 has an RPN of 128, which is the highest among the given failure modes, indicating the highest risk involved.
FMEA RPN is calculated by multiplying Severity, Occurrence or Probability, and Detection indexes. In this example, Failure Mode 2 has the highest RPN = 8 x 4 x 4 = 128.
