Many organizations believe that business continuity, and especially formally documented continuity planning, is a luxury only large corporations with lots if time and money need to worry about. In reality, every organization is going to face challenges and threats and having a plan to deal with them will cost less time and money in the long run by eliminating having to run around trying to figure out how to put fires out.
The plan needs to be documented and not kept in someone’s head. What happens if that person is incapacitated? That possibility should be included in the written plan.
