The investigation will typically point to a particular failure of a component. The methodology is now applied to find the significance of the failure. -Its is based on a simple equation where $S$ ranks the severity (or cost \cite{fmea}) of the identified SYSTEM failure, +Its is based on a simple equation where $S$ ranks the severity (or cost \cite{bfmea}) of the identified SYSTEM failure, $O$ its occurance, and $D$ giving the failures detectability. Muliplying these together, gives a risk probability number (RPN), given by $RPN = S \times O \times D$.
