  • You would like to implement Lean, Lean Six Sigma or Continuous Improvement but don’t know how.
  • You would like a proven systematic approach to tackle business problems and inefficiencies without the need for sophisticated statistical tools. The Advanced Green Belt programme is designed to include the data techniques to measure and analyse processes.
  • You know very little about process improvement or…
  • You already have a lot of experience in process improvement and would like to understand how the techniques you know about fit together in a powerful, coherent structure.
  • You are from a service or manufacturing organisation.
  • You would like to become a British Quality Foundation Certified Lean Six Sigma Green Belt with the associated career enhancement opportunities.
  • You are ready to begin your journey towards becoming a Black Belt – we’ve found that learning the project principles first on this course and then adding advanced Statistical and Change tools through further training modules is a much more effective way to progress, compared to jumping straight into the black belt course.
