Lean Six Sigma Green Belt

The Lean Six Sigma Green Belt training combines Lean principles with statistical techniques to thoroughly analyse and improve processes. You will work according to the DMAIC model and learn how to use data to identify problem causes and implement sustainable solutions.

This approach is particularly suitable for more complex processes where variation and errors play a significant role. In addition to practical Lean tools, you will develop skills in measuring, analysing, and substantiating improvements. This enables you to make decisions based on facts rather than assumptions, leading to better performance, higher quality, and more predictable results within organisations.

What do you learn in a Lean Six Sigma Green Belt training?

You will learn how to improve processes using the DMAIC methodology (Define, Measure, Analyse, Improve, Control). In addition to Lean tools, you will also work with data analysis and statistics to identify problem causes and implement structural improvements.

Upon completion of the Lean Six Sigma Green Belt training, you will be able to:

• Manage breakthrough projects according to the DMAIC method
• Systematically analyse waste and process variation
• Objectively assess processes using data and statistics
• Translate critical customer requirements into measurable CTQs
• Visualise and analyse data with Minitab
• Substantiate root causes of problems with statistical techniques

What are the distinctive techniques in the Lean Six Sigma Green Belt training?

In addition to the Lean basics, you will learn statistical techniques such as measurement system analysis, hypothesis testing, capability analysis, and design of experiments. A 6-month Minitab licence is included within this training. This allows you to achieve data-driven improvements and demonstrably reduce process variation.

What does a Lean Six Sigma Green Belt project deliver?

A Lean Six Sigma Green Belt delivers measurable quality improvement by optimising processes in a data-driven way. Errors and variation are demonstrably reduced. Examples include shorter lead times (up to 50%), controlling noise factors, and reduced defects (target: Cpk 2.0 or 3.4 ppm defects).

Which format suits me best?

The Lean Six Sigma Green Belt training is offered in four variants.

• Standard: 8-day classroom training
• Fasttrack: accelerated 6-day training (requires more self-study and experience)
• Bootcamp: intensive 5 days + 4 evenings, including overnight stay and dinner at an inspiring location
• AI Opex: accelerated 6-day training + 2 days AI for Operations

If you have already completed a Lean Green Belt training and wish to upgrade to Lean Six Sigma, please contact one of our training advisors.

Twice a year, during the holiday period, we provide a Bootcamp variant. This is an intensive training course of 5 days and 4 evenings at an inspiring location in the centre of the Netherlands.

The training prepares you for the Lean Six Sigma Green Belt exam of the Lean Six Sigma Academy (LSSA), an internationally recognised certification body. The LSSA certificate is used worldwide by training and examination institutes, including the University of Twente, APMG International, and EXIN. In the Netherlands, the certificate is issued by the University of Twente and is worth 5 EC.

The exam is optional and consists of a theoretical and practical part. For the practical exam, you must carry out a DMAIC project at Green Belt level.

Symbol is an ‘Accredited Training Organisation’ (ATO), where you can order an exam voucher and receive guidance for your practical project.

You will receive all the materials you need during and after the training.

• Textbook and Exercise Book: ‘Climbing the Mountain’ book set (Dutch or English)
• Digital learning environment: access to an online platform with instructional videos, exercises, and interactive content
• Minitab: free 6-month licence included (Symbol is a Minitab Gold partner)
• Templates: directly applicable in your own organisation
• Certificate of participation: upon completion, you will receive an official certificate of participation from Symbol

The books in the ‘Climbing the Mountain’ series (H.C. Theisens, Director of Symbol) have sold over 50,000 copies worldwide.
