The 4th Edition of Strategic Management of Technology and Innovation by Burgelman, Christensen, and Wheelwright continues its unmatched tradition of market leadership, by using a combination of text, readings, and cases to bring to life the latest business research on these critical business challenges. New co-author Clay Christensen provides his insights on innovation management and new market entries through several new cases. Approximately 40% of the cases are entirely new to this edition.Strategic Management of Technology and Innovation takes the perspective of the general manager at the product line, business unit, and corporate levels. The book not only examines each of these levels in some detail, but also addresses the interaction between the different levels of general management - for example, the fit between product strategy and business unit strategy, and the link between business and corporate level technology strategy.Each part of the book starts with an introductory chapter laying out an overall framework and offering a brief discussion of key tools and findings from existing literature. The remainder of each part offers a selected handful of seminar readings and case studies. Almost all of the cases deal with recent events and situations, including several that are concerned with the impact of the Internet. A few "classics" have been retained, however, because they capture a timeless issue or problem in such a definitive way that the historical date of their writing is irrelevant.
