Lean Six Sigma Yellow Belt

The Lean Six Sigma Yellow Belt training is designed to provide delegates with a good high level understanding of Lean Six Sigma methods and prepare them to participate, as contributors, to Lean Six Sigma projects. Yellow Belts are not experts in the methodology, but understand the activities, deliverables and key concepts of Team problem solving.

Yellow Belts are also expected to help identify potential improvement opportunities in their organisation and provide Subject Matter Expertise to support Green and Black Belts.

Yellow Belt training is also the entry level for Green Belt certification, so delegates can choose to continue on their Lean Six Sigma journey once they have had an opportunity to appreciate how these methods can deliver Business benefits to their organisation.

There is no exam at the end of the LSSYB. Yellow Belt certificate is issued upon completion of the training.
