Failure Modes, Effects and Criticality Analysis

FMECA. Qualitative analysis of the modes of possible failures, of the effects and of critical conditions, of the Bottom up type, in which the possible anomaly of a component, or subsystem, and the possible consequences in the circuit to which it belongs is considered. Extension of the FMEA method; it takes into account the importance of each failure and concentrates the analysis on the areas of risk, assessing their criticality. See PHA, HA
