Drawing on techniques developed by experts from MIT, The University of Chicago, and the Center for Management of quality, as well as product development experiences from hundreds of top companies, such as Abbott, Compaq, Lockheed Martin and Cisco, this book reveals market-driven product definition techniques. Managers can use these techniques to: determine customer needs and value-based requirements; choose which requirements to satisfy in order to distinguish their products from the competition; determine which trade-offs can and must be made in product development; and decrease time to market by up to 40 per cent and minimize time to profit.
