The traditional view of the finance function is to manage the financing of the firm’s operations. The more liberated view is to help figure out what the best investment opportunities are and then to provide the finance in the most profitable way for the firm.
This means that the main functions relate to evaluating investment opportunities i.e. to help analyze the profitability of any new projects and new strategies, perhaps involving the acquisition and/or divestment of other businesses.
On the other side, the functions relate to financing - the payment of dividends, the raising of debt, and equity.
