To me, this is a great business and management book. It includes a wide array of examples you can use to improve not only your management skills but how you approach business in general. This book is a great guideline.
I also feel it could be applied to your normal life as well. So much of this book, like being cautious of how much you waste and how much you buy and by making the correct decisions in life. Planning, doing, reviewing, and then fixing so that the decisions are correct and save you the most time.
Head on over to the Lean Six Sigma and Lean Box Set product page on Amazon. From there you can find out more about these books, see what other people are saying about it, and you can pick up this set for yourself.
