We rarely get advance notice that a disaster is ready to strike. Imagine leaving work on a Friday and coming back Monday just to find out that there was a fire in your building over the weekend and everything in your office has been destroyed. There is no question that this will have a significant impact on your organization and its ability to operate moving forward.
Even with some lead-time though, multiple things can go wrong; every incident is unique and unfolds in unexpected ways. This is where a business continuity plan comes into play. To give your organization the best shot at success during a disaster, you need to put a current, tested plan in the hands of all personnel responsible for carrying out any part of that plan. The lack of a plan does not just mean your organization will take longer than necessary to recover from an event or incident. You could go out of business for good.
