26.8 Risk Priority Number
Risk priority number (RPN) is a function of the three parameters discussed above, viz, the severity of the effect of failure, the probability of occurrence, and the ease of detection for each failure mode. RPN is calculated by multiplying these three numbers as per the formula below,

where S is the severity of the effect of failure, P is the probability of failure, and D is the ease of detection.
RPN may not play an important role in the choice of an action against failure modes, but will help in indicating the threshold values for determining the areas of greatest concentration. In other words, a failure mode with a high RPN number should be given the highest priority in the analysis and corrective action. The relationship between the above mentioned parameters of FEMA may be represented as in Fig. 26.3.
