criticality-analysis

Criticality-analysis is a risk-assessment method that assigns a numeric criticality score to each failure mode or hazard by combining three rated parameters: severity (the seriousness of the consequence), occurrence (the frequency or probability of the cause happening), and detectability (the likelihood that the cause or effect will be discovered before harm occurs). The method uses standardized scoring scales (typically 1-10) multiplied or tabulated in a criticality matrix to produce a prioritized ranking that determines which failure modes require corrective action first. Parameters: scoring scales defined by the applicable standard (MIL-STD-1629A for reliability-critical systems, IEC 60812 for industrial FMEA), a criticality matrix or formula mapping the three parameters to a score, and a threshold above which mitigation is mandatory. Persistence: maintained through documented procedures in safety management systems, regulatory frameworks, and engineering standards that prescribe the scoring methodology and matrix structure.
