When is the best time to fix your roof: after the rain stops, during the rain or before the storm? Pre-disaster planning can serve to support and sustain disaster mitigation and recovery efforts, if created well in advance of any disaster or emergency. By discovering the “leaky roof” in your emergency plans before the emergency, you have the option of repairing the holes in your recovery plan rather than being forced to apply the security equivalent of a tarp or a bucket to mitigate the damage.
