Green Belt is the first Lean Six Sigma qualification that gives you the skills you need to tackle projects first-hand. You’ll be equipped with the tools and knowledge you need to run small, department-level projects independently, and to assist the Black Belt on larger, more complex problems within your place of work. If you are unable to run a project for any reason, we can provide case studies.

Our training allows you to learn at your own pace and spend as long as you need on challenging topics before moving on. As the course comes with email support from a dedicated Master Black Belt, you can be sure there will always be someone to talk to if you need help during and after your training is complete.
