Conventional thinking holds that family-controlled businesses are beset by inherent weaknesses from "clan" cultures to stable ownership that hobble success and erode competitive advantage. This book argues that those very traits are part of what has ensured the sustained success of some of the world's leading and long-lived family controlled businesses. This is not a book for "mom and pop" family businesses. Rather, it is for firms of all kinds and sizes who want to emulate the strategies of the best family-controlled businesses for long term success.
