When doing a Criticality Analysis for a FMECA, keep in mind the following (select all that apply):

1. A Criticality Analysis is the same as a Risk Priority Number (RPN) calculation in FMEA procedure.

2. Quantitative Criticality Analysis calculation uses the mode ratio of unreliability

for each potential failure mode as part of its calculation.

3. Qualitative Criticality Analysis uses severity and detection risk rankings.

4. A criticality matrix can be used to graphically plot criticality versus severity.
