7 Best Lean Six Sigma Books for All Experience Levels

There are lots of lean six sigma books on the market, but which one is the best? We will show you 7 lean six sigma books that are easy enough for everyone.

Why is Six Sigma Important?
From the inception of six sigma in the 1920s by Walter A. Shewhart, people always say "Six Sigma is Dead!". However, we believe six sigma has changed the world in so many ways. In fact, six sigma is thriving and has become the building block of practitioners in operations management, supply chain management and service management.

To provide lean six sigma book recommendations, we search on various lean and six sigma blogs and forums. What we've found is that most recommendations are done lightly. They don't take into account of the most important principle of six sigma, namely, "Voice of the Customer" or VOC.

Some bloggers use sales rank in lieu of the actual VOC but is it acceptable? We dig deeper and find that sales rank is not the actual sales record, but it's the combination of 2 main factors such as book categories and probability to generate sales. Moreover, these data are not very transparent.

Finding the Best Lean Six Sigma Books
In order to determine which lean six sigma book should be recommended, we conduct 2-step data collection as below,

Firstly, we check each lean six sigma book if it got endorsement or positive review from business leaders and six sigma gurus.

Secondly, we turn to a technique called Altmetrics. Altmetrics are a set of metrics used to measure the impact of books, scientific articles, videos, presentations etc. Moreover, Altmetrics use data that are available to public. In this section, we will demonstrate how we collect Altmetrics and how they reflect Voice of the Customer.

- Worldcat: Worldcat is the world's most comprehensive network of library. When you access Worldcat site, you can search for publications that you would like to read and it will show you how many copies are available and where the publications are stored.

Worldcat reflects the "Voice of Library Staffs" who are trained to spot, acquire and store quality contents.

- Google Scholar: Google scholar shows how many times each publication is cited by scientific articles, trade publications and books.

"Citation Counts" reflects the "Voice of Authors and Writers". A lean six sigma book with high citation counts means it's widely accepted by peers (one citation is equivalent to one vote).

- Amazon.com: the last Altmetric we're going to use is "number of reviews written on Amazon.com"

We know for the fact that business people buy the books on Amazon.com then the number of positive reviews (3 star or more) of every edition of a book will be used as the last metric (one positive review is equivalent to one vote). Again, book reviews reflect the "Voice of Practitioners".

Then, we combine the composite scores and rank lean six sigma books by total score. Finally, we remove out-of-print and obsolete lean six sigma books from the list.

We sincerely believe this lean six sigma book recommendations will be useful to your future endeavors and we will update the list on a regular basis. If you find useful lean six sigma books you would like to share, please drop the line to bloggeradmin [at] supplychainopz [dot] com.
