Welcome to the 15th edition of Concepts in Strategic Management and Business Policy! All of the chapters have been updated and we have added one new chapter on Global Strategy. The theme that runs throughout all 13 chapters of this edition continues our view from the 14th edition that there are three strategic issues that comprise the cornerstone all organizations must build upon to push their businesses forward. Those are globalization, innovation, and sustainability. Each chapter incorporates specific vignettes about these three themes. We strive to be the most comprehensive and practical strategy book on the market, with chapters ranging from corporate governance and social responsibility to competitive strategy, functional strategy, and strategic alliances.
