This groundbreaking book on corporate-level strategy is the fruit of ten years of consulting and research with corporations in North America, Europe, and Japan. Michael Goold, Andrew Campbell, and Marcus Alexander have focused on the question of how parent companies create-or destroy-value in the businesses making up their organizations. They propose a new approach to the management of multibusiness companies, based on the goal of "parenting advantage": being the best parent for each of the businesses in the corporate portfolio. Multibusiness corporations around the globe are grappling with fundamental questions about what businesses their companies should be in, and how they should structure and influence their businesses. For many companies, restructuring and divestitures seem to be the sensible solution. But the authors of Corporate-Level Strategy show that size and diversity are not necessarily problems. More often than not, the fatal flaw is not the range of businesses in the portfolio, but the lack of a corporate strategy that will add any value to them. Corporate-Level Strategy arms senior managers and corporate planners with a set of proven strategic principles and clear guidelines for successfully managing a diverse, multibusiness company.
