Summary.
You can’t make intelligent investments within your organization unless you understand how your whole industry is changing. If the industry is in the midst of radical change, you’ll eventually have to dismantle old businesses. If the industry is experiencing incremental change, you’ll probably need to reinvest in your core. The need to understand change in your industry may seem obvious, but such knowledge is not always easy to come by. Companies misread clues and arrive at false conclusions all the time. Sotheby’s, for example, invested in online auctions (its own Web site as well as a venture with Amazon) as if the Internet were just another channel; in truth, the new technology represented a fundamental shock to the industry’s structure.
