How important do you think an experience in Finance ( corporate finance, IB, PE etc.) against one in the Operations of business ( Marketing&Sales, Operations) is important for the success of acquiring and growing a company?

Put in a simple way, my view is the discipline of Finance is crucial, but at the end of the day the numbers seem to be the result of delivering value created in operations and sold to clients. Finance will organize and might enable it with additional properly projected investments.
