You may be the best race driver in the world. However you will never beat a below average driver with a tricycle when they have a full-blown red-bull F1 car.
You may be the best fighter pilot in the world. However you will never beat a below average pilot using a glider and peashooter when they have a loaded F-35 aircraft.

An organisations decision framework is also a tool. A tool which impacts revenue and profitability. It also impacts the lives of its employees. The lower the rank the higher the impact. A C-grade CEO with an excellent existing decision framework will be many years ahead of an A-grade CEO who needs to create one.
