Upon completion of this course, you will be able to:
- Apply Lean Six Sigma principles in your daily work
- Identify and eliminate waste
- Reduce errors using data-driven techniques
- Apply the DMAIC method to solve problems in a structured way
- Work with tools such as 5S, Value Stream Mapping, Kanban, and Kaizen

What is the difference between Lean and Six Sigma?
Lean Six Sigma combines two powerful improvement methods. Lean focuses on speed and efficiency: eliminating waste so processes run more smoothly. Six Sigma focuses on quality and error reduction: “to measure is to know” is the guiding principle. Together, they form a complete approach to process improvement that can be applied in any organization.

No, you do not have to take a traditional exam for the Lean Six Sigma Yellow Belt course. In our online Lean Six Sigma training, it works as follows: After every key lesson, you will receive several test questions in the form of a quiz. These test questions together constitute your ‘exam’. Throughout the entire Yellow Belt training, you will therefore answer several of these test questions.
You can take the test questions as often as you like. If you do not achieve a good score the first time, you can review the material from the relevant lesson and take the quiz again.
After the Lean Six Sigma White Belt comes the Yellow Belt. The Lean Six Sigma program structures the development of knowledge and skills through a belt system, similar to levels in, for example, judo. Here is the order of the belts with a description of what each phase involves:
- Lean Six Sigma White Belt – Provides an introduction to the basic principles of Lean Six Sigma.
- Lean Six Sigma Yellow Belt – Builds on the basic principles and introduces more advanced techniques.
- Lean Six Sigma Orange Belt – This training is the perfect stepping stone for professionals who want to progress to a Green or Black Belt.
- Lean Six Sigma Green Belt – In this training, you develop the knowledge and skills to independently lead improvement and change initiatives.
- Lean Six Sigma Black Belt – After completion, you are able to independently initiate and lead improvement projects, and guide your organization toward optimal processes and continuous improvement.
- Lean Six Sigma Master Black Belt – The highest level, where you become an expert in Lean Six Sigma methodologies and principles at a management level.
The Lean Six Sigma Yellow Belt is the second step; each subsequent belt further deepens your knowledge and skills.
Our Lean Six Sigma Yellow Belt training is suitable for anyone who wants to contribute to a culture of continuous improvement within their organization and independently tackle smaller Lean Six Sigma improvement projects. No specific prior knowledge is required.
