Lean Six Sigma Green Belt

This program provides a comprehensive and practical foundation in Lean Six Sigma Green Belt tools, methods, and improvement techniques, equipping participants to lead process optimisation projects and reduce operational variation and waste. The course focuses on mastering the DMAIC framework, applying statistical analysis, and driving measurable improvements within teams and business functions.

In addition, the course introduces the Black Belt Pathway, outlining the competencies, leadership capabilities, and analytical methods required to progress to the next certification level. Participants leave with the skills to support continuous improvement initiatives and the strategic roadmap to advance toward Black Belt expertise.
