The Lean Six Sigma Green Belt certification is a mid-level qualification designed for professionals looking to lead process improvement initiatives within their organisation. It builds on the foundational knowledge of Lean and Six Sigma and equips learners with the tools, techniques, and confidence to manage improvement projects and deliver measurable results.
The course provides in-depth training in the DMAIC (Define, Measure, Analyse, Improve, Control) framework, statistical analysis, root cause identification, and change implementation. Learners gain practical skills to lead projects, analyse data, and work effectively within cross-functional teams.
Achieving the Lean Six Sigma Green Belt certification demonstrates that an individual can take a proactive role in driving operational excellence, lead small to medium-sized projects, and apply structured problem-solving methods to improve quality and efficiency across a wide range of industries.
