Lean Six Sigma Yellow Belt


You learn the most basic about Lean Six Sigma and how to improve your own processes using structured problem-solving.

This includes setting clear goals, obtaining data and facts to uncover causal relationships, introduce simple, effective solutions that last.

The course combines 2 web meetings of 2 hours with 1 day classroom.


About the course


You learn to use an A3 template to solve problems / improve processes a systematic way, using 7 steps:

Start with Background, understand Current situation, set a Goal, Analyze and prove root causes, consider Measures and create an Implementation planFollow up to ensure lasting results.

The first web meeting teach you how to use an A3 for basic problem solving.You use the A3 template to solve a relevant problem and submit it for feedback. In the next web meeting, all participants receive feedback on their A3.

Between the 2 web meetings, there is a 1-day classroom course where we use a Lego game to practice structured problem solving and Lean solutions to reduce waste. The classroom training lets you practice A3, process mapping and lean principles to improve flow using a Lego game.


Learning objectives


This training enables you to:

  • Learn a structured method to solve problems and improve processes.
  • Practice structured problem-solving, and receive feedback that helps you improve.
  • Visualize activities with process maps to understand the big picture, improve collaboration, and discover opportunities for improvement.
  • Recognize waste (activities that do not add value).
  • Learn Lean solutions that can eliminate or reduce waste.
  • Practice Lean solutions in an engaging Lego game developed by Cardiff Business School and Revere.
  • Create lasting results


In the first webmeeting you learn to use an A3 template (see picture) to solve problems successfully:

  • Introduction to problem-solving
  • Lean & Six Sigma
  • Comparison of A3, DMAIC & PDCA
  • 7 step problem-solving:
    1. Select a problem and describe why (what are the gains?)
    2. Measure current situation
    3. Decide Y and set specific goal)
    4. Understand "Y = f(x)", identify, measure and prove root causes (Brainstorming, Fishbone, 5 Why)
    5. Identify possible solutions and choose the best ones based on your decision criteria 
    6. Implement chosen solutions
    7. Follow-up (ensure lasting results)
A3 template

Between the 2 online meetings, you solve a relevant problem using the A3 template.

In the last web meeting (~1 month after the first meeting), all participants receive feedback on their A3.

Choose a problem that is realistic to solve in 1 month. If your A3 is not completed, we can go through what you have.


  • Introduction and practical information
  • Continuous improvement
  • Introduction to Lego game
  • Round 1 of Lego game
  • Describe background and current situation
  • Set a specific goal

  • Finding solutions using Lean principles:
      • One-piece-flow versus batch
      • Reduce Change-over-time & Standardization
      • Takt and balance

We use Lean principles and solutions to improve a Lego manufacturing process.

The game was developed by John Bicheno at the Lean Enterprise Research Center and further developed by Joakim Hillberg at Revere in Sweden.

Companies, universities and consultants from several countries use this game to provide practical experience and understanding of Lean principles.
