Online Lean Six Sigma Green Belt course: data-driven improvement, completely at your own pace!
What do you learn during the Lean Six Sigma Green Belt?
The Green Belt training takes approximately 55 hours on average and deepens your knowledge of the Lean Six Sigma methodology through the five DMAIC phases, with a strong emphasis on practical application. Throughout the training, you will work on your own case study or assignment, proving that you can truly apply the material.
The case study or assignment
With the case study or assignment, it is not a matter of right or wrong. You simply apply the Lean Six Sigma methodology to a situation from your own work, whether large or small. You will map out a process description, identify waste, analyse the data and root causes, and come up with solutions. Next, you will draw up an actionable implementation plan, demonstrating how you can truly apply the material. You will be provided with the accompanying template and step-by-step guide during the training, so you won’t have to start from scratch.
Are you currently “in between jobs”, or do you not have a suitable case study close at hand at the moment? No problem. Give us a call, send a WhatsApp message, or email us, and we will work together to find a case study of ours that suits you.

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