Putting Lean, Agile and Six Sigma into practice

We strive for results

We are a consultancy and training company located in the Netherlands. We are fully committed to make Lean, Agile and Six Sigma really work in practice. Of course others might say that too, but we really do it. We help you so that you achieve results for your organization. We have been doing this since 2012 by training, coaching you and ensuring that you can implement changes successfully yourself.

We offer:

✔️ Unique combination of Lean, Agile and Six Sigma
✔️ Focus on practice
✔️ Coaching included in training
✔️ Ability to take the exam immediately

Flexible and seasoned

It starts with our trainings. We are flexible. We connect them to your organization by approaching the training courses in a unique way. After all, every student has a different need, is in a different situation and does a different project.

We can do this because we have seasoned trainers who breathe the material. You learn Lean, Agile and Six Sigma, and especially improve and change in such a way that it actually delivers the desired results in your situation.

Energetic, personal and pleasant

Our years of experience make us thorough, and we are quite proud of that. Students experience our approach as energetic, fresh, personal and pleasant. They say that sometimes they almost see us as colleagues. And that they feel at home at our training locations. We experience it the same way. Please contact us if you want to know more about us. Or see which Green Belt, Black Belt or other training we have planned for you. We are happy to help you!
