Criticality matrix

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

For example, an aircraft might have the following matrix:

Failure mode Severity Probability
Collision High Low
Engine failure High Low
Ice buildup Medium High
