It is no coincidence that this book is included as required literature in management courses at all leading business schools in the world. The authors described complex change processes in a very simple way; It was they who first introduced the concept of reengineering into the business lexicon in the early 90s. Since then, the concept of reengineering has had its ups and downs. With the beginning of the era of globalization and commercial use of the Internet, reengineering ideas are again in demand by the most successful Russian and international companies. The book will be of interest to all those involved in transformation, be it a huge corporation or a small business that has grown out of a trading tent.
