Critical Infrastructure Resilience Metrics
Measure availability, interruption, recovery, condition and dependency risk.
Systems note: infrastructure classifications, standards and responsibilities vary by country and operator. Use current local requirements for real decisions.
Why this matters
Measure availability, interruption, recovery, condition and dependency risk.
Core system ideas
No single metric captures resilience.
Availability and outage duration show service performance, while recovery time and dependency exposure reveal different aspects.
Metrics are most useful when tied to decisions and consistent definitions.
What to review
Useful reviews usually combine service criticality, dependencies, condition, capacity, maintenance, alternate arrangements, restoration time and clear ownership rather than relying on one isolated metric.
