The main focus of this course is the application of Lean Six Sigma DMAIC methods to real life improvement projects within the delegate's own organisation. There are two anticipated entry points to this course: 1. Previous Yellow Belt training – the Green Belt course covers all of the material taught on the Yellow Belt course and serves as a refresher and then builds on the Yellow Belt knowledge.
