Great class
This is a great self-paced online class. I appreciated being able to review completed chapters. The examples used were extremely helpful in my understanding of green belt concepts.

Quite informative
Quite informative. For me it was mostly review, however, there were a couple things I did not know or think about. I would recommend others to look at this program. I am considering the Black belt program through goleansixsigma.

I liked the lessons
I liked the lessons. Each one was easy to follow. I believe even if a student was not familiar with Lean Six Sigma, he or she would have no problem comprehending and retaining the information

Great course
This was a great course to take. Learn at your own pace and pickup right where you left off. The Green Belt course was challenging but very well done.
