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 improve processes and solve problems a systematic way, using A3 and DMAIC. 

The first web meeting teach you how to use an A3 for basic problem solving. 

The second web meeting goes into more depth of the 5 phases of DMAIC.

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.
  • Identify problems and make them measurable.
  • Visualize activites using process map.
  • Define clear goals.
  • Collect data and facts to understand current situation
  • Improve flow by using Lean principles and reduce waste.
  • Introduce simple and effective solutions.
  • Create lasting results.

Structured problem-solving


The A3 template helps you follow and document 7 steps to improve processes: 

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.

Webmeeting 1

You learn to use an A3 template based on 7 steps 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)

Webmeeting 2

You learn to improve your own processes using DMAIC:

  • Understand customer need and make them specific (Define)
  • Process mapping (Define / Measure)
    • SIPOC
    • Process variable mapping
  • Data collection (Measure)
  • Measure current situation for your key metric Y (Measure)
  • 8 wastes (Analyze)
  • Prove root causes (Analyze)
  • 5S & Standard work (Improve)
  • Mistake proofing (Poka-yoke) (Improve)
  • Visual Management (Control)
  • Wrap-up


  • Introduction and practical information
  • Continuous improvement
  • Introduction to Lego game
  • Round 1 of Lego game
  • Describe background and current situation
  • Set a specific goal
  • Identify waste using process mapping
  • Finding solutions using Lean principles:
      • One-piece-flow versus batch
      • Reduce Change-over-time & Standardization
      • Takt and balance
      • Cross-training
      • 5S & Lean lay-out
      • Visual management
  • Decide improvements for Round 2 of Lego game
  • Play Round 2
  • Evaluate results
  • Wrap-up and key learning


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.
