Criticality provides a means of ranking the failure modes. In this form, FMEA is upgraded to failure mode, effects, and criticality analysis (FMECA).4,5 FMECA

I was interested in the missile reliability, and I was shown the failure mode, effects and criticality analysis (FMECA

Failure mode effects and criticality analysis (FMECA) is a more involved process than failure mode and effects analysis (FMEA), which is widely used today in industry as a "what if" process. The difference is that FMECA attaches a level of criticality to the failure modes so

    tools used in the risk analysis process are the failure mode and effects analysis (FMEA)/ FME and criticality analysis (FMECA), which is a bottom-up approach starting at the component level, and the fault tree analysis (FTA), a top-down method. Campbell said that FMEA might typically involve

These methods identify each component of the medical device, their potential modes of failure, the predicted risks posed by each failure mode, and the means to reduce the risks to acceptable levels.
