Lean Six Sigma Yellow Belt

The Lean Six Sigma Yellow Belt training teaches you not only how to improve processes, but also how to better understand them using data. You will discover how variation arises, its impact on performance, and how to recognise it within your own work environment. As a team member, you will contribute to structural and evidence-based improvements.

You will be introduced to Lean principles and the basics of the Six Sigma approach, without the need for complex statistics. Through practical exercises, you will experience the effect of variation and learn the importance of measurement and analysis. This will help you develop a strong foundation to more effectively support improvement projects.

Who is the Lean Six Sigma Yellow Belt training intended for?

The Lean Six Sigma Yellow Belt is suitable for any employee directly or indirectly involved in process improvement. No prior knowledge of Lean or Six Sigma is required.

This training is suitable for:

• Employees who wish to implement improvements in their own work environment
• Team members contributing to Green or Black Belt projects
• Employees who want to understand the impact of variation
• Employees in organisations where both Lean and Six Sigma are applied

Improve processes with Lean and data for demonstrable results

The Lean Six Sigma Yellow Belt combines practical Lean techniques with an initial step into data analysis. You will learn not only to improve processes but also to substantiate them with facts. Ideal for situations where errors, variation, and complexity play a role.

In this training, you will learn:

• To reduce waste and analyse processes
• To work with 5S (professional work environment) and Value Stream Mapping (VSM)
• To investigate problems using Ishikawa and 5 Why
• To recognise variation and understand basic measurement
• To support Lean Six Sigma projects

What is the benefit of a Lean Six Sigma Yellow Belt training?

A Lean Six Sigma Yellow Belt training offers added value by combining process improvement with a data-driven approach. You will learn not only where waste occurs but also why processes deviate and how to substantiate this with facts. This makes improvements demonstrable and more sustainable.

This training is particularly valuable in environments where quality, error reduction, and predictability are important. The Lean Six Sigma variant is the ideal choice if the Yellow Belt participant is part of a Lean Six Sigma Green Belt project where processes are improved in a structured and measurable way.

The training prepares you for the Lean Six Sigma Yellow Belt theoretical exam from 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.

Symbol is an ‘Accredited Training Organisation’ (ATO), where you can order an exam voucher.

You will receive all materials needed during and after the training.

• Textbook and Workbook: ‘Climbing the Mountain’ book set (Dutch or English)
• Digital learning environment: access to an online platform with instructional videos, exercises, and interactive content
• 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.
