I didn't necessarily mean double the amount of people...but at least have enough cross training that a single person won't cripple your company. I've seen this far too many times that one or two people have too much of the key knowledge for a group and if one or both are all of a sudden gone (for any reason) then the rest of the team is absolutely screwed. Rotating job scopes and responsibilities is one of the best ways to ensure you have knowledge redundancy in my opinion...although depending on the team this may be extremely difficult, but still necessary.
