Hopp gives a good introduction to manufacturing and supply chain dynamics. I found the content to be a well organized review of supply chain flow, inventory and buffer management operations. In some respects, I think of the content as "Supply Chain Mathematics", since much of the book is about measuring and optimizing the performance of a supply chain. As such this book discusses the management of inventory and flow rather than concepts such as selection of suppliers, contractual relationships, etc.
It is worth noting that the book includes a discussion & definition of value chain analysis within a factory, then expands to consider multiple factories and distribution. Hopp includes useful examples from manufacturers as well as service providers, including quite a few areas which would not be typical users of lean techniques.
This is an introductory textbook, with well ordered chapters and discussion problems/questions for each chapter. A helpful outline summarizing the principles is found on the inside front cover of the book.
