Recovering from a disaster begins way before the event occurs. It starts by anticipating threats and developing goals that support the business’s continuity of operations.

A goal must contain certain key information, such as the following:

• Authority In times of crisis, it is important to know who is in charge.
• Priorities It is extremely important to know what is critical versus what is merely nice to have.
• Implementation and testing
