This is about making businesses resilient. The good news is, it's not as hard as you think!

Planning for emergencies is a necessary precaution. Always plan for a disruption, whether it's a major earthquake or a minor short-term power cut. If you haven't already, now is the time to develop a business continuity plan.
Practice and review your plan from time to time to make sure that it is understood by the rest of your team.
