This book is a part of three books series to guide easy implementation. There are some conflicts between Rajeev and my TOC CCPM understanding. I also think that there are typos in the book. This is the weakest book in the series. At the end of the book there are a bunch of relevant softwares listed. It is full of repetitions and unnecessary advices. I strongly suggest to read Forget The Urgent by Mathias Birrel and TOC Insights of Goldratt himself, TOC.tv videos of Goldratt rather than this book.
