Thus, the value of the firm is the discounted present value of the stream of expected future profits. Each of the functional areas of business plays an important role in managerial decision making since each area provides vital input into the value maximization process. The marketing department of a firm has a major responsibility for sales, the production department a major responsibility for costs, and the finance department has a major responsibility for acquiring the capital necessary to support the firm's investment activities.
