By Armando
The Lean Six Sigma Leader training was fantastic in so many levels. First, my experience was very positive, overall very engaging and extremely beneficial therefore it exceeded my needs. Second, the knowledge of so many complex sets of concepts was so skillfully delivered that I enjoy going back to it to reference the key take-aways as I progress in my maturity of Operational Excellence. Last, the structure of the course made navigating and virtual learning so much more fun that I may just rate it higher than in-person learning. Overall, kudos to both Tracy O'Rourke and Elisabeth Swan for welcoming me so warmly in their circle of students.

Great instruction would like a continuous refresher course in the future, very much needed process in business development.

Excellent course. I was able to easily fit it into my workday. I liked the sidebar with everything that was being said, typed out and readable. I learn quicker from reading than listening. Both tied together was great.
