Green Belt
Green Belt is for people who will actually lead improvement projects. You'll leave able to write a project charter, collect and analyse data, test hypotheses, and present capability results to executives.
Most learners complete in 4-6 weeks at 5-6 hours per week. The course includes a guided mini-project so you apply every tool to a real scenario.
