Why a CFO or COO may not fit for a CEO?

CFO’s & COO’s have reached the top level of their skill set and without them a CEO cannot advance the vision

But this does not mean that they are fit for the top job to lead the vision

Many once they get the top job , they are more likely to continue to do what they are good at i.e. thinking about margins EBITDA ,EPS , market share rather than embracing the responsibility of advancing a just cause to realize a vision
