One platform running one discipline, evidence-based trigger monitoring, applied to the decisions that carry the most weight. Pick the problem that matches yours.
A continuity plan names the conditions that activate it. Very few organisations check those conditions daily. When a crisis builds slowly, there is then no moment anyone can point to and say the plan was formally activated.
Crisis tooling tends to optimise for volume. More feeds, more alerts, more dashboards. In a real escalation your crisis team is working on something much narrower: whether the conditions you agreed in advance have been met, and whether you can show it.
The hardest evacuation decisions are the gradual ones. Airspace narrows, advisories tighten, a border closes for a day and reopens. Each signal on its own can be explained away, and then the options have closed.
Leaving a market has a playbook. Going back rarely does. Once operations are suspended the pressure to return builds week by week, from revenue, contracts and competitors, while the evidence for a safe return stays vague. The decision often comes down to a site visit and a feeling.
ISO 22301:2019 asks for more than a documented plan. Clause 8.2 expects a business impact analysis with defined disruption conditions. Clause 8.4 expects continuity strategies with clear activation criteria. What auditors most often find missing is the operational loop: evidence that those criteria are being monitored, and that activation decisions trace back to them.
