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.

Great training course and very easy to follow. I recommend GoLeanSixSigma to anyone looking to expand their process improvement skills.

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.

Well organized information, good examples, nice tools included for use.

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

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.
