What are the prerequisites?

None – this course assumes no prior knowledge of Lean Six Sigma. You do not need Minitab software to complete this programme as many Green Belt projects, particularly in non-manufacturing environments do not require the level of statistical training which would involve statistical software. However, there are free to use graphical tools on the Catalyst website which are included in the training.

Lean Six Sigma Green Belt


This six-day programme provides the route to attaining benchmark British Quality Foundation Green Belt Certification but is equally for delegates who simply want to find out in detail what Lean Six Sigma is and how it works.
