The course is well structured with clear & easy to understand examples which will relate to the core of the discussion. The timing of the videos are short to avoid boredom & hence you can keep the interest alive even if you are covering in installments. Thank you Udemy.

By Brad Piscitelli on 12/18/2019

In addition to this course, I paid hundreds for a course from an accredited training company for Lean Six Sigma. I found this course to be superior to the far more expensive one. The instructor takes complicated subjects and makes them simple with clear examples to make the material relatable. While the other course covered some charts and formulas that this did not, I feel more equipped to apply Lean Six Sigma principles in real life based off the training received here. This course helps you understand high level concepts for success and is not just focused on memorizing definitions and formulas. I would highly recommend it.

By Sheriff Olalekan Ajala on 11/17/2019

I learned new things and also aware of the importance of some known statistic tools prior to this class. The lectures were well delivered. I guess the lecturer can improve in the areas of how some of the charts are generated (by any of the statistical tool). Great lectures!!!

By Robert Young on 10/24/2019

lack of context, could be good bit vague so far, terrible editing with some content being repeated multiple time. Overuse of acronyms with no attempt to explain meaning, lots of content introduced at random and not explained Slideware generally good but occasional typos which clearly should have been corrected by now, this is a pretty old course. Sometime hard to understand and close captioning is ridiculously poor early on

By Pritesh Shetty on 9/21/2019

Someone without Yellow Belt will easily follow up and understand however this is surface scratch discussion here. The lecture note transcript is missing which is essential for effective revision and application not only the slides. The lecture is interesting and straight to the point provided the exam shall be straight forward like this.

By Rodrigo Osorio Barra on 7/26/2018

Interesting course for unexperienced people who want to learn the six sigma concepts and applications. Very organized topics and videos divided in phases. I just recommend include subtitules because the accent of the instructor isn't to clean and understandable in several times, but nothing that you can't accustom yourself to.

By Shashwat Soumya Dash on 7/23/2018

A well designed six sigma green belt course for which you get ascb certification at such low price is commendable. Mr Nital Zaveri is an excellent trainer and his personality shows the experience he has in dealing with six sigma projects. His voice is also convincing and overall he has a very friendly attitude that keeps you engaged in the subject.

By Sohan Roy on 6/25/2018

The course is very much detailed and awesome. The instructor gives a lot of information and the course is very satisfying. The experience was pleasant and never did it feel monotonous. Good use of images and graphs and examples to illustrate points and topics. I look forward to more of such courses related to quality and I request them to bring out such courses on Udemy.

By Hiren Kakkad on 3/6/2018
