In some way or at some time every business is limited by the limitations of the man who started it.
For many businesses the problem is that the entrepreneur feels that he has to micromanage everything, even when he knows the business has grown too big for him to do it. By making it necessary for all decisions to continue to go through him, he creates a constant bottleneck.
Other businesses are stalled because they are built around the talent or skill of the top man. These businesses stop growing when the boss can’t do any more than he is already doing.
