Just because you have the skills to be a solid Controller, this does not mean you have the right stuff to become a Great CFO….
To become a Great CFO, one needs to be able to move beyond the technical of accounting and finance. Having great Excel skills, being a GAAP Geek or being able to add 100 numbers in your head within 60 seconds is not what a CFO does. If a CFO needs to these things, there is a good chance a CFO will hire you. That might be why you were hired, but these skills will not get you the CFO job.
