Lean Six Sigma

I found the course extremely well organised and easy to follow. John’s depth of knowledge and teaching style made the content easy to follow and engaging. I really appreciated the interactive components as they kept the sessions lively and helped reinforce the material. Having the slides in booklet form and the extra resources on Moodle was also incredibly helpful. I would absolutely recommend this course to anyone interested in completing Six Sigma Green Belt training.

The course is very interactive and engaging. Good content and examples provided

I would recommend this course to a colleague because the DMAIC structure, hands‑on tools, and real‑world application make it highly practical and immediately useful. The content gave me clear guardrails for problem‑solving, strengthened my ability to validate root causes with data, and highlighted how to create sustainable controls. While some areas could benefit from more practice or deeper exploration, the overall value and clarity of the methodology make it a strong foundation for anyone involved in process improvement.

The course was great but I think a little bit more energy and understanding we need people to buy in at the start . The facilitators are excellent in lean knowledge but could use their facilitators skills more to bring the late adopters on the journey too

I appreciate all of the context and recording! I really enjoyed the group sessions and working with the different individuals on example templates that will and can be used prior to the greenbelt. Thanks John! Awesome job!

It was an excelente course, thank you John and ferring for the opportunity!

Tutor was very patient and very clear in explaining things, thanks for you support

It was well structured and highly practical, and it gave us a clear understanding of DMAIC and how to apply the tools effectively to achieve real results. I want to specifically highlight Ashling Keogh, who delivered the sessions with exceptional clarity and depth. Her wealth of knowledge and coaching, especially during the mentoring and A3 review, helped us understand the material in depth and build confidence in applying it to our project work. I’m proud of what we achieved and learned, and I’m confident this will be a lasting benefit in my day-to-day work and for future projects in our organisation.

It was really a great learning experience for me and well facilitated by John Ryan. I would highly recommend this course to others.
