Six Sigma Black Belt Certification Guide

A Lean Six Sigma Black Belt is a professional who can initiate and implement large-scale and cross-functional Lean Six Sigma projects. He or she should know how to apply advanced techniques and statistical methods. He or she should demonstrate team leadership, understand the various team dynamics, and should have the ability to teach and mentor Green and Yellow Belts. A Six Sigma Black Belt should demonstrate understanding and competence in using the tools illustrated in the following map:


Here are examples of the tools that are taught in any Six Sigma Black Belt training:
