Product development is key to profitability. Without well-designed products that meet the needs of customers at a reasonable cost, the firm has no sales. And without sales, the firm has no profit. But designing profitable products is hard. Eppinger, et al. (1994) estimate that for a mod- erately complex electro-mechanical product, close to a million decisions must be made before the product is brought to market. Many of these decisions are routine, but many are not. The two product-line-optimization papers in this journal address hard decisions.
