Lean Six Sigma Green Belt Training and Certification is a practitioner-level programme designed for professionals who are expected to lead defined improvement projects and deliver measurable performance improvement within their area of responsibility.
The programme builds a strong working foundation in Lean and Six Sigma principles and applies them through the Define–Measure–Analyse–Improve–Control (DMAIC) framework. You develop the capability to scope improvement opportunities, analyse process performance, use data to support decisions, manage change locally and implement improvements that deliver sustainable results.
All course content, learning resources, assessments and exams are supported with multilingual language capability, enabling participants to learn, collaborate and apply tools effectively across global and cross-functional environments.
By completing the Green Belt, you return to work equipped to lead structured improvement projects end-to-end, contribute confidently to organisational performance goals and support the development of a continuous improvement culture within your team or function.
