Lean Green Belt

How can you work more efficiently, shorten output times, and improve customer satisfaction? Lean is an internationally acclaimed method for improving processes. You’ll learn to trace, analyse and reduce process-related problems. You’ll also develop the competences you need to lead improvement projects and secure changes. You’ll lift yourself and your organisation to a higher level.

This course leads to the Lean Green Belt certificate. You will receive the certificate after successfully completing the related practical assignment.
