Question 5
You are the risk official in Bluewell Inc. You are supposed to prioritize several risks. A risk has a rating for occurrence, severity, and detection as 4, 5, and 6, respectively. What Risk Priority Number (RPN) you would give to it?
Correct answer: A
Explanation:
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.

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.
