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.

This Virtual Classroom format combines the structure and discipline of instructor-led training with the flexibility of remote delivery. It is designed for professionals who want real-time interaction, guided learning and accountability, without the need to travel or step away from work for extended periods.
Delivered live by an experienced Master Black Belt, the programme runs through a series of interactive virtual workshops. Sessions are paced to ensure concepts are understood, applied and reinforced, with time between workshops to reflect and begin applying learning in your own work environment.
Unlike self-paced learning, the Virtual Classroom creates a shared learning journey. You learn alongside other professionals, engage in live discussion, ask questions as they arise and benefit from facilitator insight drawn from real organisational improvement projects.
Key benefits of the Virtual Classroom format
- Live instruction and facilitation by an experienced Master Black Belt
- Real-time interaction, discussion and Q&A
- Structured learning schedule that maintains momentum and focus
- Peer learning with professionals from a range of industries
- Time between sessions to reflect and apply learning in the workplace
- Full access to the Green Belt Bootcamp platform and learning resources
The Virtual Classroom is ideal for professionals who value guided learning, interaction and structure, but who need the flexibility of remote attendance. It works particularly well for individuals who prefer to learn through discussion and explanation, as well as organisations looking to train geographically dispersed teams together.
This format combines self-paced eLearning with live, instructor-led virtual sessions, giving you flexibility without losing structure or depth. Core concepts and tools are introduced online, allowing you to prepare at your own pace and revisit topics as needed.
Online preparation feeds directly into the live sessions, so virtual classroom time is used for discussion, application and deeper understanding rather than passive learning.
Online learning includes:
- Purpose-built instructional videos
- Interactive exercises and quizzes
- Case studies and practical resources
- Guided discussions supported by Master Black Belts
You complete approximately 34 hours of online learning, structured into manageable blocks around professional commitments.
The programme follows the DMAIC methodology, enabling you to apply learning as you progress rather than waiting until the end. Tools and techniques are introduced in a practical sequence, helping you shape improvement ideas early and refine them as your capability grows.
By combining continuous access to learning materials with live discussion and peer input, you develop solutions that are relevant to your organisational context.
By the end of the programme, you will be able to apply Lean Six Sigma tools to real improvement initiatives, set clear priorities and action plans, and confidently contribute to or lead improvement projects.
