Excellent training
Thank you for the excellent training. Your intuitive and engaging approach made the concepts easy to grasp, and I truly appreciated the interactive and insightful sessions.
Green Belt training
Anita Stalin was great, really helpful and had some fantastic examples which made understanding easier. Also loved the notetaking and diagrams. It was a full on week and the statistics were difficult for me, but thoroughly enjoyed the week. Thank you Anita!
Good online course, good service
The online course was good - the videos were of a good quality and the tutor was very knowledgeable, experienced and engaging and explained the concepts very well. The coursework helped give practical examples. However, once the course was completed my account was inactivated even though I had access until March 2025. It was fortunate that I downloaded all of the PDFs of the presentations but I would expect my access to continue until its end date. Moreover, when I emailed the company asking for my account to be re-activated, they ignored my email.
PS: thank you for your response, my access to the course has been reactivated and extended by a month. Thank you so much for your help.

BLACK BELT
Very well explained course with practical examples. This course has broadened my knowledge about lean six sigma.
High quality days!
Very competent and skilled staff. The lessons given by John were enjoyable and engaging. The many practical examples made complex concepts much simpler. Many thanks again!
Insightful and engaging experience
I am incredibly grateful to John for participating in my participation observation study. His valuable insights truly helped shape my thinking, particularly around the importance of focusing on lean digital systems rather than using terms like six sigma. There is a need to emphasise lean principles and concepts to improve digital infrastructure and systems, which has significantly influenced my research approach. His expertise and thoughtful contributions were highly appreciated!
The Green Belt course
The Green Belt course is well structured and materials are well prepared. John is a great teacher with lots of real life case studies which help to understand the concepts. I can highly recommend the course to anybody who wants to deep dive into Lean Six Sigma world.

Great use of Gamification and hand-on exercises in classroom
I was very impressed by the use of games and practical exercises used in the classroom training this really helped to drive home the principles and tools of Lean 6 sigma. Highly recommend for LSS training.

Great Practical Learning Experience
I recently completed a self-paced Six Sigma Black Belt course with ILSSI and it was a great experience. The course included lots of practical and universal examples, as well as useful calculation tools. The flexibility of the course allowed me to learn at my own pace. Additionally, there were plenty of extra resources provided to support my learning. I highly recommend this course and the ILSSI institute.
Best experience with this company
Best experience with this company. I've made all 3 belts with them Yellow, Green and Black and keen to do more at the right time. No regrets. Thank you
Simply Amazing
Good Learning Experience
When I first thought about some terms like SIPOC and many, I was not sure about how the implementation is, but I know now how it's applied with a very basic examples explained by Anita. That's the journey I have completed in 5 days duration.
