Infrastructure Resilience Explained
How essential systems prepare for, absorb, adapt to and recover from disruption.
Why this matters
How essential systems prepare for, absorb, adapt to and recover from disruption.
Core system ideas
Resilience is broader than preventing failure: it includes maintaining priority functions, adapting when normal arrangements fail and restoring service.
Redundancy, spare capacity, alternative routes, trained staff, information, maintenance and mutual assistance can all contribute.
A resilient system balances reliability during routine conditions with recoverability during unusual ones.
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.
