Lean Six Sigma training was very beneficial for me, especially the “discovery” of for me entirely new approaches to change, measure and evaluate processes. Phasing out and links in DMAIC, which direct me to another point of view on my own work in the company of O2 was especially crucial for me. The training had an ideal form with prevailing practice over theory, with the active involvement of participants in the exercises and different stages of improving and simplifying the process. The simulation game had drive and was a real enlivening of the training. At the same time, I was very satisfied with the instructor called Václav Jiránek, who led the training showing great experience and expertise. He was maximally willing, helpful and using witty remarks or examples.
