Very engaging instructor. He uses fun and interesting examples to explain concepts in ways so can remember them. I recommend this course and this instructor.

By Adedeji Oluwatosin Adeloro on 7/17/2026

Intellectually satisfying and practically sound a course. The instructor possesses a remarkable mastery of the course and teaches with a flow that characterizes a mature Lean Management System.

By Sean Brewis on 5/22/2026

The content is fine but a 20+ question timed quiz is over the top. Quiz is good but this isn't collage, you need to allow time for people to check their notes and respond. Also, if I need to sit through this much content and answer this many questions, there should be a cert at the end of it. Overkill

By Bob Hoffman on 5/11/2026

Some of the editing is poor in this training. It hasn't taken away from the content, but it's unprofessional.

By Dasan Wanniarachchi on 5/6/2026

It's really engaging and interesting to know more about lean six sigma strategies. One of the few things I got more from this was how adaptable is lean and six sigma. Both have the same synergy and purpose when it comes to the level of minimizing the risk and optimizing the workflow and quality of each project and work.

By Yazid Eka Putra on 4/1/2026

The explanation provided by the instructor in this learning session was easy to understand and offered very valuable information for my career development.

By Sudhish Kumar on 3/27/2026

This has been amazing training which cleared much of the operational concepts and highlighted six sigma approach, how it can stream line the process

By Carmen Marlick on 12/30/2025

I enjoy the short video explanations. Very informative, lecturer is very cool and calm to listen to as well. thank you.

By Salih Gulsen on 12/17/2025

The content and explanation was great and crystal clear! While grouping the exams are nice, it also feels like you might have put some quick quizzes in between to keep it more interactive. But in overall, this one was one of the best courses that I have taken.

By Bart Stanley on 11/24/2025

Its a great course so far. It is also user-friendly, unlike some other previous courses that I've taken, from different websites.
