The manufacturer of an expensive machine announces a successor model, but in the camp are still several devices from the current production. Sales gets the order, these devices soon to sell, if necessary, with high discounts. Sales sells twice as many as any, because nobody knows that the stock is depleted. What to do? The customers say that their orders had to be canceled, and thus lose customers? Or new equipment to provide special conditions? A salesperson handles several dates. When he arrives at the customer, he learns that even before the deadline was postponed hours. A half day is lost.
