Create a business continuity plan to preserve business

The business continuity plan, a superset of the disaster recovery plan, is a comprehensive description of the steps to take, people to contact and methods to apply for a rapid mitigation, so as to return to a stable situation (even if this is not yet at the normal level of production).

A business continuity plan, well-tested and sent out to all staff, facilitates the quickest and calmest return to a normal (or near-normal) working mode, without time being lost because people need to figure out who does what and when.
