Yes. Lean Six Sigma Black Belt covers concepts and tools that are related to Lean and Six Sigma toolkits and creating a Lean culture. If it’s just Six Sigma, then many Lean tools wouldn’t be covered.

Follow-up Question: In my comparison with different companies’ curricula, I noticed that one of the other two spends quite a bit of time on use of Minitab and also addresses completely different issues like:

Central Limit Theory, Multiple Regression, Nested Anova, DOE Planning, Factorials, Advanced Graphical Analysis, Multi-Vari Planning, Variation Trees and Funneling, Hypothesis Testing, Central Limit Theorem, Statistical Analysis Roadmap, Test for Mean with t-test, One Way ANOVA, Non-manufacturing Applications, Multi-Vari Analysis, Process Control Plan.

Everything listed below is covered in’s Black Belt curriculum:

  • DOE Planning
  • Factorials
  • Advanced Graphical Analysis
  • Hypothesis Testing
  • Statistical Analysis Roadmap
  • Test for Mean with t-test
  • One Way ANOVA
  • Non-manufacturing Applications
  • Process Control Plan

We make software training optional with the choice of using Minitab or Sigma XL. We have self-directed instructions and we provide data sets, instructions and graphical examples for all tools. tries to keep things as simple, practical and relevant as possible. Some of the other tools mentioned may not be used very often by some industries, or only exclusively in a manufacturing environment. We could cover all the tools under the sun, but we choose to prioritize the tools that get used most often by Black Belts.
