How to Learn Six Sigma for Free


Six Sigma is a system of quality measure that seeks to eliminate errors. Although it can be argued that Six Sigma concepts go back centuries, it was an engineering team at Motorola in the late 1980s that trademarked the term, expanded their quality measures and created a process of eliminating errors that could be measured and duplicated. That team saved Motorola $16 billion with their efforts.

A Six Sigma process produces no more than 3.4 errors (or defects) per million opportunities.

Although Six Sigma certification costs money in the form of exams, you can learn Six Sigma principles and find helpful project templates for free.


  • There are six levels of Six Sigma professionals, and each has very defined roles. The American Society for Quality (ASQ) defines this as follows:

    "Project level roles include black belts, master black belts, green belts, yellow belts and white belts. These people conduct projects and implement improvements. There are also two Organizational level positions, Champions and Executives, who assist with deployment and strategic focus."

There are several places on the web offering Six Sigma concepts for free.


  • The acronym "DMAIC" is central to the Six Sigma philosophy. Coined by Motorola in the late '80s, these letters stand for "define, measure, analyze, improve, control."
