7 Best Six Sigma Books of All Time

Many people think six sigma book is too hard to understand. In this article, we will show you the list of six sigma book that everyone can study and learn.

In Search of the Best Six Sigma Books
From the inception of six sigma in the 1920s by Walter A. Shewhart, six sigma is thriving and has become the building block of practitioners in many fields.

To survey six sigma book landscape, 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.

In order to determine which six sigma book should be recommended, we conduct 2-step data collection as below,

- Firstly, we check each six sigma book if it got the 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 the public. In this section, we will demonstrate how we collect Altmetrics and how they reflect Voice of the Customer.

1. WorldCat: WorldCat is the world's most comprehensive network of the 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.

2. 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 six sigma book with high citation counts means it's widely accepted by peers (one citation is equivalent to one vote).

3. 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 stars 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 six sigma books by total score. Finally, we remove out-of-print and obsolete six sigma books from the list.

In short, we use objective evaluation with metrics such as citation count and customer reviews and only books endorsed by industry leaders are included on the list.

We sincerely believe this 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 six sigma books you would like to share, please drop the line to bloggeradmin [at] supplychainopz [dot] com.
