Judging Risk priority number RPN by absolute value can be misleading
Risk priority number RPN is calculated as a product of a) Severity b) Occurance and c) Detection. Each values being max 10, RPN is maximum 1000.
One of the commonly made mistake is that many people become complacent by absolute value of RPN. That can be misleading. This is particularly true if RPN # is low but customer has concerns.
What is essential is to take a look at relative magnitudes of RPN to prioritize improvement actions.
It is helpful to generate pareto of top RPN # and compare with customer concerns to decide business case for asking resources for working on improvement projects.
