Criticality is the importance level of a CI to your organization. Criticality values range from A to E, where A is the highest Criticality and E is the lowest Criticality (with equally spaced intermediate values). This value is used to calculate Alert Impact (the maximum Alert Severity multiplied by the maximum Criticality equals Alert Impact).
Criticality values are listed in the Component Views - CI Service Table display. Criticality values are also shown in heatmaps and tables.
