Books To Read For a Six Sigma Certification

Six Sigma certification validates your level of training and proves that you have the required level of knowledge to pass the exam.  Six Sigma uses martial arts terms to describe the two main levels of certification.

There are dozens of books that can help you understand Six Sigma, learn the techniques in-depth and prepare you for the certification exam. The books listed here will complement your Six Sigma training and serve as reference guides.

1) The Certified Six Sigma Green Belt Handbook

by Roderick A. Munro and Govindarajan Ramu (ISBN-10: 0873898915)

Published by the American Society for Quality (ASQ), this book is, as the name claims, a handbook, containing explanations of all Six Sigma areas at the Green Belt level. It included terms, processes, acronyms, and reference material. The book follows ASQ’s Body of Knowledge for the Green Belt Certification and comes with two CDs which contain mock-exams, a video course, and helpful additional material.

This book provides an overview of Six Sigma, and it can be used as a reference guide to answer questions that may arise during your studies for the test. However, it is intended to be a handbook and is not a training manual for the exam. When ordering, be sure to get the latest edition as its content is continuously updated to match the ASQ Body of Knowledge (BoK) for the Certified Six Sigma Green Belt, which is updated on a regular basis.

It is a comprehensive reference to a variety of methods and techniques used for quality improvement. The reader will find explanations of a number of widely used quality control tools (for example, the fishbone diagram, the Pareto chart) as well as the newer management and planning tools.

Summary

None of these books is a one-stop preparation resource for the Six Sigma exam. Learning the Six Sigma methodology takes more than rote memorization of test questions from mock exams. One needs to possess a thorough understanding of the methodology involved, after which passing the exam should be a walk in the park.

These books will help you understand the many aspects of the Six Sigma methodology. We recommend you choose those which are appropriate for your level of knowledge and needs and will complement other training resources.
