The old resiliency model was an annex: a disaster-recovery binder, a backup site, an annual tabletop. Then a pandemic, a ransomware epidemic, supply shocks, and a string of infrastructure outages compressed a generation of disruption into a few years—and exposed the binder as theater. What replaced it is an operating posture: resiliency as a property of how the organization runs, not a document it owns. Ten rules capture the shift.
Key Takeaways
- Resiliency moved from IT annex to operating posture—it is designed into processes, suppliers, and systems.
- The unit of planning is the business service, not the server.
- Rehearsal beats documentation: untested plans are hypotheses with letterheads.
- People and decision rights—not technology—are the binding constraint in real incidents.
01The ten rules
1. Plan around business services, not systems. “Order-to-cash must survive” is a plan; “the ERP server has a backup” is an inventory line. Map the services that earn revenue, then the systems, people, and suppliers each depends on.
2. Assume the disruption is plural. Real crises stack—the cyber incident during the supply shortage during the key-person departure. Single-scenario plans break on contact.
3. Rehearse or it isn't real. Restore drills, failover exercises, decision tabletops—on the calendar, with findings tracked to closure. The gap between documented and rehearsed is where companies die.
4. Make immutability non-negotiable. Ransomware hunts backups first; offline or object-locked copies are the difference between recovery and negotiation.
5. Distribute the single points of failure—including human ones. The engineer who alone understands the billing system is a continuity risk wearing a lanyard. Document, cross-train, rotate.
6. Treat suppliers as part of your blast radius. Tier them by criticality, demand notification clauses, and rehearse the loss of the top three. Their incident is your incident with a delay.
7. Pre-authorize the crisis decisions. Who can disconnect the network, pay a vendor by alternate means, or speak publicly—decided in daylight, written down, with deputies named.
8. Build financial shock absorbers. Cash buffers, insurance that has been read (not just renewed), and contract terms that flex—operational resiliency fails fast when the balance sheet can't fund it.
9. Instrument for early detection. The cheapest disruption is the one caught as an anomaly—monitoring across systems, supply signals, and security telemetry buys the hours that matter.
10. Close the loop. Every incident and exercise ends in a blameless review whose actions get owners and deadlines. Resiliency compounds only if the organization metabolizes its lessons.
02Where to start
Pick your three most revenue-critical services and run them through rules 1, 3, and 4 this quarter—map the dependencies, schedule the rehearsal, verify the immutable copy. Most organizations discover their real resiliency posture in that first honest pass; the rest of the rules then prioritize themselves. Partners like Semifly earn their place here—not by writing a thicker binder, but by operating the disciplines (tested backups, monitored infrastructure, rehearsed recovery) that make the binder true.
