In a Perfect World the CEO is a Team

"In a perfect world, you will have a team at the top of a company that includes the founder(s) and a group of top notch operating executives.

They should operate as a team and like, respect, and engage each other in the key issues.

The person who is making the final call may change from time to time.

In times when you need great creativity and risk taking, you probably want a founder in that role.

In times when you need focus, discipline, and execution, you probably want an operating executive in that role."
