Welcome to Six Sigma Study Guide!
Lean Six Sigma is a proven methodology used to deliver outstanding business results. Practitioners who understand this material and can apply it in the real world are in demand. Employers look to various credentialing agencies to certify levels of understanding and application by level often referred to as belts. Six Sigma Study Guide exists to help you learn Six Sigma concepts, study efficiently and effectively to help you pass your exam, build your career and prepare you for applying this knowledge in the real world.
Learning Six Sigma
Six Sigma involves many practitioners but concepts are divided into three generally-recognized skill levels. Expectations and exams are structured around an governing body’s suggested body of knowledge and geared to the level.
You can learn all necessary concepts for free by following these links. Each Six Sigma topic has a page on this website with my study notes. Either follow the links in the study guide outline or use the search function on the right hand side. If any concepts are not clear, leave a comment at the bottom of any page or leave a note in the forum. (Note: free membership required to access forum, it cuts down on spam.)

How to Apply Six Sigma in the Real World
The best way to master this material is to apply it. While studying interact with others doing the same. Post comments on articles and interact with the forums.
Look for opportunities everywhere to apply this knowledge; at your job, at a place you volunteer, at home, when talking with friends who work in different positions or even different industries – there is no shortage of opportunities out there. A great way that I have found to study is to try to explain material to others.
