The class was great. Only 4 stars because I wish there were workbooks that went with each section that I could use and keep as reference material.

Great course

This was a good beginning if you have never had any lean experience before. Introduces the concepts and terminology.
By Steven
I would have preferred to receive the tests right after each session. Also the ability to go back to the information provided in the sessions to facilitate the tests.

Will recommend any one who wants to get their Lean Six Sigma to get it from here..A+

good course content, just felt some of the modules time wise were too long , where there were obvious cut off points to alleviate the content, and make the course more enjoyable, the IMPROVE step was a prime example of this for me!. Feedback after every exam would also help with the learning experience, it would solidify the knowledge gained, and highlight areas to focus on in futur..

I had a wonderful learning experience with Goleansixsigma. The course was quite interactive and i enjoyed every bit of it. With the tests, i suggest you create an avenue where the student gets to know at the end of the test which of the questions he missed and the correct answer to that question. It will enhance the learning experience. i am really looking forward to my black belt program and i think you can encourage more of your students by reducing the cost.
