The CEO–COO Relationship Isn’t a Division of Labor. It’s a Decision-Making Partnership.

Most companies define the CEO–COO relationship by dividing responsibilities. Role clarity matters, but it is not enough. The stronger model is a decision-making partnership where strategic ambition and operational evidence can challenge each other without the relationship breaking. When that works, the COO is not simply executing strategy downstream—they are helping test the assumptions that determine whether the strategy will actually create value.
