Failure mode, effects, and criticality analysis Wikipedia
The failure mode may then be charted on a criticality matrix using severity code as one axis and probability level code as the other. For quantitative assessment, modal criticality number C m {displaystyle C_{m}} is calculated for each failure mode of each item, and item criticality number C r {displaystyle C_{r}} is calculated for each item.
