For example, management may learn that for one product line, the costs of being a full-line producer are not justified by the benefits. In such a product line, the firm should produce only the high-volume products or drop the line altogether. Another product line may also show that substantial costs result from being a full-line producer. But buyers of the low-volume products in that line may be willing to pay prices high enough for the firm to continue the full line and perhaps even to reduce prices on the high-volume products.
