A
Steps involving in calculating risk priority number are as follows: ✑ Identify potential failure effects ✑ Identify potential causes ✑ Establish links between each identified potential cause ✑ Identify potential failure modes ✑ Assess severity, occurrence and detection ✑ Perform score assessments by using a scale of 1 -10 (low to high rating) to score these assessments. ✑ Compute the RPN for a particular failure mode as Severity multiplied by occurrence and detection. RPN = Severity * Occurrence * Detection Hence, RPN = 4 * 5 * 6 - = 120 Incorrect Answers: B, C, D: These are not RPN for given values of severity, occurrence, and detection.
