Johnson focuses not so much on the development of new technologies and products as on the implementation of new business models. A successful business model depends on four aspects--a customer value proposition (CVR), a profit formula, and the key resources and processes that need to be in place in order to deliver value to the custstomer. Building on this simple model, Johnson explores, using a number of case studies, how companies can move into transforming existing markets, creating new markets, and emerging in a strong posisition from times of industry upheaval.
