Criticality matrix
 | This article needs more citations. (June 2024) |
In operations research and engineering, a criticality matrix is a representation (often graphical) of failure modes along with their probabilities and severities.
Severity may be classified in four categories, with Level I as most severe or "catastrophic"; Level II for "critical"; Level III for "marginal"; and Level IV for "minor".[1]
Example
[edit]For example, an aircraft might have the following matrix:
| Failure mode | Severity | Probability |
|---|---|---|
| Collision | High | Low |
| Engine failure | High | Low |
| Ice buildup | Medium | High |
