Lean Six Sigma Yellow Belt
Tired of fixing the same problems over and over? Learn to solve root causes, not just the symptoms.
Format: 2 web meetings (2 x 2 h) + 1 day classroom with Lego simulation.
You work on a real problem from your own organisation throughout the course, with personal coaching along the way.
Who is this for?
This course is for you if you:
- Spend your days fixing yesterday's problems instead of building better systems for tomorrow.
- See the same issues come back again and again, and wonder if you're missing something.
- React to whatever shouts loudest, but aren't sure what actually matters.
- Are responsible for results, but feel you have little control over the processes that deliver them.
- Want to stop blaming people when you know, deep down, that the system is the real problem.
"A bad process will beat a good person every time." — W. Edwards Deming
It's not the person. It's the process. And that's exactly what this course teaches you to fix.
Includes certification
What will you get out of this?
- Solve the root cause of a problem, not just the symptoms that keep coming back next week.
- Map your processes and see where time actually goes, not just where you think it goes.
- Test Lean solutions in practice through a Lego simulation, and see the effect of improvements in real time.
- Receive personal coaching for one month while solving a real problem in your own organisation.
- Earn a Lean Six Sigma Yellow Belt certificate when you complete your own problem-solving project.
Previous participants have achieved documented results ranging from NOK 10,000 to 400,000 per year. We have trained approximately 200 and certified 112 participants as of 2025.
What participants say
"Great mix of theory and practice. Really enjoyed trying out what we learned, especially the Lego game, which made everything concrete."

How the course works
- Web meeting 1 (2 hours): Introduction to structured problem-solving. You choose a real problem from your organisation and begin mapping the current situation and its root causes.
- Between the meetings: You work through your problem using a structured method, with personal coaching available throughout. This is where most of the learning happens.
- 1 day classroom: Lego simulation where you test Lean solutions in practice and see the effect of improvements in real time. (This is usually the "aha" moment: you see that it was the process, not the person.)
- Web meeting 2 (2 hours): You present your problem-solving work and receive feedback. Complete this, and you earn your Lean Six Sigma Yellow Belt certificate.
Web meetings
Web meeting 1: Introduction to structured problem-solving.
- Select a problem and set your focus.
- Map the current situation.
- Set a specific goal.
- Understand possible causes and prove the most important ones.
- Identify possible solutions and evaluate them.
- Implement your chosen measures.
- Follow up to ensure lasting results.
Web meeting 2: Feedback on your own problem-solving work.
There is approximately 1 month between the web meetings. During this time you work through a relevant problem using structured problem-solving.
Choose a problem that is realistic to work on over one month. If you have not completed all the steps, we will go through what you have.
If you have questions along the way, you have access to support throughout the course period.

Hands-on exercises with Lego
We use Lean principles and solutions to improve a production process that manufactures Lego products.
The game was developed by John Bicheno at the Lean Enterprise Research Centre at Cardiff Business School, and later adapted by Joakim Hillberg at Revere in Sweden.
It is used in multiple countries by companies, universities, and consultants to provide practical experience and understanding of Lean principles.

Do I need prior knowledge of Lean or Six Sigma?
No. The course is designed for anyone who wants to learn structured problem-solving, regardless of experience. We start with the fundamentals and build from there.
How much time do I need to set aside?
The web meetings and classroom day are fixed: 2 x 2 hours plus one full day. The time you spend working on your own problem between the meetings will vary.
Those who get the most out of the course are typically those who take the time to do the work properly. Not because we require it, but because that's how lasting results happen. A thorough problem-solving process now saves you months of firefighting later.
What kind of problem should I choose?
Choose a problem that is realistic to work on over one month and that matters to you or your team. It could be anything from long lead times to high scrap rates or inconsistent quality. You will get guidance on this in the first web meeting.
What is included in the price?
2 web meetings, 1 classroom day, personal coaching for 1 month, course materials, problem-solving templates, and a certificate upon completion.
What is the difference between Yellow Belt and Green Belt?
Yellow Belt teaches you to solve problems at the root cause, not just the symptom. You work on a real problem in your own organisation and implement measures that actually hold.
Green Belt goes further: you learn to lead improvement projects and realise savings in the millions. The average documented saving per project is $213,000 (source: GLSS).
Start with Yellow Belt if you are new to structured problem-solving.
I have tried to improve processes before. Why will this be different?
Because most improvement attempts stop at the symptom, not the root cause. This course gives you a structured method for finding and proving what is actually driving the problem, along with tools to make sure the solution sticks.
Can I use this even if I am not a manager?
Yes. Many participants are specialists, operators, and project managers without people management responsibilities. What you need is access to a real problem you can work on, and the motivation to do something about it.
What if I don't finish solving the problem within one month?
That happens. You are working on a real problem in a busy working environment, and things come up. In the second web meeting we go through what you have managed so far, and you get guidance on the next steps. Many participants finish their problem-solving after the course ends.
Does this work for my industry?
The method works regardless of industry, because it is about processes, not products. We have participants from manufacturing, healthcare, construction, the public sector, and more. The problem you choose comes from your own everyday work.
