Weill (director, the Center for Information Systems Research, MIT's Sloan School of Management) and Vitale (director, the Australian Graduate School of Management) provide established firms in all industries with a strategic framework for analyzing, choosing, and implementing e-business enterprises. They describe eight business models that represent the core building blocks of all e-business ventures, based on a detailed study of 50 online initiatives in traditional firms, and explain how to create an e-business model schematic for assessing and combining business models. Case studies of companies such as Lonely Planet, GE Supply Company, and Reuters illustrate each business model. Annotation c. Book News, Inc., Portland, OR (booknews.com)
