How we scored them

The Shelf Score weighs fit, contents and edition, value, and listed reading level. None of the picks list a reading age or grade level. How we pick explains the weights.

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.

How to choose the best six sigma books

Match the book to the belt level

The Council guide covers White, Yellow, Green and Black Belts, so it suits a beginner and a certification candidate alike. The Pocket Toolbook speaks to Green and Black Belts, while the Brook guide addresses trainees and managers.

Check the edition and the page count

Editions run from the 2002 first edition of Lean Six Sigma by George to the 2022 Ries collection, with Brook in a 6th edition from 2020. Page counts run from 160 pages to 828 pages. On a business book list, edition year matters.

Pick a format: reference, roadmap or collection

The Pocket Toolbook is a quick reference, the George book is a roadmap, and the Ries set is a three-book collection. A self-improvement book reader who uses Minitab should pick the Brook guide.

Before you buy

• Check the edition and publication date: Brook is a 6th edition from January 1, 2020, while the George book is a 2002 first edition.
• For a series, buy Book 1 first: the Ries collection is listed as Book 1 of 3.
• Check whether Minitab matters: the Brook guide is compatible with Minitab 19 and 20.
