The title of the book speaks for itself. Managers in this book are people who manage other people, regardless of their number (from the foreman to the general director). However, the target audience of the book is not only them, but also anyone who wants to better understand the philosophy of Lean Manufacturing, those who are concerned about the problems of increasing the level of efficiency in the organization. The main difference of this work is a brief and accessible presentation of only the most necessary material that is required at the initial steps for implementing Lean Manufacturing.
