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?
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
Compute the RPN for a particular failure mode as Severity multiplied by occurrence and detection.
RPN = Severity * Occurrence * Detection
RPN = 4 * 5 * 6
