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.

Successful completion results in Lean Six Sigma Green Belt certification.
This format is designed for professionals who value immersive, in-person learning and want dedicated time away from day-to-day work to focus fully on developing their Lean Six Sigma capability. Delivered in a public classroom setting, the course combines expert instruction, practical exercises and peer learning to accelerate understanding and confidence.
Across five consecutive days, you will work closely with a Master Black Belt instructor and a cohort of professionals from different organisations and sectors. Concepts are introduced, explored and applied in real time, with continuous opportunity to ask questions, test ideas and learn from the experiences of others in the room.
The classroom environment supports deep learning through facilitated discussion, group problem-solving and hands-on application of tools. You will work through the DMAIC methodology step by step, using real-world examples and case material to ensure concepts translate directly back into your workplace.
By the end of the week, you leave with a strong practical grasp of Lean Six Sigma tools, a clear understanding of how to apply them, and the confidence to lead improvement initiatives in your organisation.
Spend five focused days working intensively with a Master Black Belt and a small cohort of professionals from different organisations. Sessions are highly interactive, combining short teaching inputs with discussion, group exercises and hands-on application to keep energy and engagement high throughout the week.
Learning is driven by collaboration and challenge. You will explore concepts together, test ideas in real time and benefit from continuous feedback from both the instructor and your peers. The diversity of experience in the room brings different perspectives to common improvement challenges and deepens understanding.
Throughout the programme, emphasis is placed on practical application rather than theory alone. Tools and techniques are explored in a way that makes it clear how they are used in real organisations, helping you leave with a clear sense of how to apply what you have learned to improvement work back in your role.
