Why this matters
Computing, software, identity and digital platforms underpinning modern services.
Core system ideas
IT systems support nearly every infrastructure sector.
Identity, networking, data, software and skilled operations are common dependencies.
Resilience includes backup, recovery, access control, change management and alternate processing capability.
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.
