Our experts
With years of experience in healthcare, banking, the manufacturing sector, and the Ministry of Justice, Anend knows what Lean means in practice. He is happy to take you into that world.
“I believe in the power of people, action, and experimentation. My ambition? To make Lean so inspiring and applicable that everyone can get started with it. Because the knowledge you gain from us must work immediately in your practice.”
Rolf makes Lean theory directly applicable in practice. Because that is what it is all about: not just understanding, but actually implementing.
“Improving and changing are nice words, but I prefer to call it continuous experimentation. The real question is: how do you get people to embrace improvements and keep using them? That is where the essence lies. And the answer? A matter of learning, but above all of doing.”
