The result of FMEA is the Risk Priority Number (RPN)
for all different possible failures. All failures might occur
are prioritized according to how serious their consequences
are, how frequently they occur and how easily they can be
detected. The RPN used to prioritize all potential failures
and helps in the decision of what actions are needed in
order to reduce the risk. This is usually done by reducing
the likelihood of occurrence and by improvin g controls for
detecting the failure (Britsman, 1993).
