The book introduces the results of a research project devoted to the study of management errors. The purpose of this study was to understand the true causes of failures and understand what kind of people were at the origins of the most famous business disasters. The research carried out allowed the author of the book to draw an amazing conclusion: companies that, at first glance, have nothing in common, fail for the same reasons. The study presented to the reader contains unique information about errors that can bring even the most powerful organization to the brink of disaster , such as GM, Mattel, Motorola, Rite Aid, Quaker, Saatchi & Saatchi or Webvan. You will get acquainted with fascinating stories, the heroes of which are not only the most famous companies, but also their top officials. In this book, for the first time, many managers and executives of major corporations talk openly about how the decisions that predetermined the fate of their companies were actually made, and what they would do differently if time could be turned back. The book is intended for managers , entrepreneurs, as well as students and teachers of economic universities.
