The subtitle of this book, Holding People Accountable for Results the Positive, Principled Way, is a good description of the book's purpose. The book starts with questions about How Did That Happen - first focusing on the financial crisis which began in 2007. Financial markets melted down, billions of dollars were lost, banks faced bankruptcy and many other businesses were in trouble. Using this as a starting place the authors ask the frequently heard question, how did That happen, and then discuss how to avoid the need for That question by using proper accountability systems.
