A failure mode and effects analysis scores each mode with severity, occurrence, and detection. The risk priority number is the product of the three. Detection runs from 1, almost certain to catch it, to 10, almost certain to miss it. A severity of 9 or 10 is a critical effect even when the product is not the largest.

The scores are filled in. Compute each RPN, name the mode with the highest RPN, and name the mode whose severity is 9.
