After reading this book, I bought a copy for all my managers. We discuss various points in our monthly meetings. As an example, there's Chapter 13: Great Store Managers Make Great Stores. It tells what the best managers do and how they manage their stores. We use it as a guide for improvement and self evaluation.
Many of my managers also use the book to help with their sales associates. There are several chapters on sales, salesmanship, and even selling from a customers point of view. The fact that this book isn't as "technical" as other retail business books I've read is a great plus. I think it's the reason my managers have been so willing to embrace the concepts and pass them along to their employees.
I highly recommend this book.
