Managers Evaluate and Adjust Each Salesperson's Estimate Before Combining Them

Managers evaluate and adjust each salesperson's estimate before combining them to form an overall forecast. The following are disadvantages of the sales force composite approach except:

A) allows estimates to be prepared by products, customers, and territories so a final, detailed forecast is readily available
B) allows salespeople to deliberately underestimate their forecast so they can reach their quotas more easily
C) yields forecasts based on present rather than future conditions, because salespeople often lack the perspective for future planning
D) requires a considerable amount of sales force time that otherwise could be spent in the field attracting new customer
