Lean Six Sigma Green Belt course (English)

For organisations to succeed in our rapidly changing world, continuous adaptation and improvement of work processes is very important. For decades, Lean Six Sigma has been the most successful improvement methodology. It solves deeply rooted causes of problems, makes work processes more efficient and involves employees towards a culture of continuous improvement.

We offer our training on location and online in our Virtual Classroom. 


During this 6-day training you learn all about Lean management and Six Sigma. We teach you how to apply the practical tools and what you can do to realise a culture of ‘continuous improvement’. After the training you will be able to manage a Lean Six Sigma improvement project from start to finish.

We train in groups up to 12 participants. They come from all regions and branches. This often leads to valuable discussions and knowledge sharing. It is nice to see that participants are often still in contact with each other after the training. We also support this by organising inspiring events, masterclasses and a half-yearly Lean reunion.

Online learning environment ‘My Bureau Tromp’

After registration you will get access to your personal ‘My Bureau Tromp’ online learning environment. Here you will find an overview of your courses and certificates obtained. You will also find the training material, e-learnings, exercises and templates here.

Content of the training

First you will get to know the backgrounds of Lean Management and Six Sigma and learn how these two methodologies reinforce each other. From here we will teach you all the important instruments from the Lean Six Sigma toolbox, the interrelationships between them and the DMAIC project structure. You can expect a lively training in which we practice with the tools. Learning by doing is the best way.

In this training we use a diversity of Lean games, videos, discussions and practical simulations. This way we bring theory into practice so you can apply what you’ve learnt in your own work environment.

As it is very important that improvements are accepted by management and employees, we devote considerable attention to change management. Think about topics such as project selection, stakeholder management and how to deal with resistance. We teach you some soft skills that will help you to get your projects on a good start.

Finally, we’ll consider the future of work processes. Lean Six Sigma plays an important role in the current digitization / robotization trend. Therefore, let’s discuss how this impacts the way we do our work.

The training is practical and interactive. Our consultant/trainer tells from his or her own experience. Moreover, we regularly ask participants about their practical examples and provoke discussions. This makes the theory a “real” story.

Duration of the Lean Six Sigma Green Belt course

The training takes 6 days spread over 3 training blocks of 2 days. The training days are from 9:30 AM to approximately 4:00 PM. The training location is the office of Bureau Tromp in Utrecht. The study load excluding training days is 3 to 4 hours per week.

Under the ‘Register’ tab you will find the starting dates and all other dates of the training courses.

For in between training blocks we give you a number of manageable assignments. Think of reading articles, going through e-learnings and implementing Lean instruments in practice. This way you can already get a taste of how it’s like in practice. It is not a problem if you do get to it. However, please realise that ‘doing is the best way of learning’. When back in the training we discuss everyone’s experiences, which often lead to great stories.

Our trainers and the CSSC certification

The Lean Six Sigma Green Belt courses are given by our experienced Lean Six Sigma Black Belt consultants. With many practical examples, they explain the theory of Lean and Six Sigma. You’ll learn how to put the Lean Six Sigma Green Belt theory into practice through simulations and exercises.

At the end of the training, there will be an examination. When completed successfully, you will immediately receive the official Lean Six Sigma Green Belt certificate from “The Counsel for Six Sigma Certification” (CSSC).
