Sometimes your business experiences interruptions that are beyond your control. Take the Super Bowl XLVII power outage. It ended up delaying the big game for over 30 minutes while more than 100 million fans were watching. Needless to say, when the lights went out, it was not only untimely but incredibly embarrassing for the New Orleans Superdome.
Disasters happen to the best of businesses, which is why it's important to have a backup plan in place. So consider your business's worst case scenarios and plan for them.
