The document discusses the concept of remanufacturing products and how it relates to new product sales. It addresses the common concern that remanufactured products will cannibalize sales of new products. However, the document argues that remanufactured products appeal to different customer segments than new products based on quality perception and price. The document provides guidance on when remanufacturing is likely to be profitable based on factors like costs, market segments, and availability of used products. It concludes that remanufacturing should be re-evaluated over the product lifecycle and may help companies reach new customers and block competition rather than just cannibalizing new product sales.
