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.

Designed around your organisation, delivered for real impact
Group Training is designed for organisations that want to build Lean Six Sigma capability at team or organisational level, not just train individuals. Teams learn together, aligned to business priorities and supported by expert coaching to ensure learning translates into measurable results.
Rather than a fixed programme, delivery is tailored to your context, culture and objectives. Training can be delivered face-to-face, virtually, through eLearning or as a blended solution, making it suitable for global and cross-functional teams.
For geographically dispersed teams, all learning content, resources, assessments and certification activities are supported with multilingual language capability, enabling consistent engagement and collaboration across regions and time zones.
Group Training is shaped around your organisation’s improvement goals and real challenges. Working with a Master Black Belt, the programme is configured to reflect your operating environment, priorities and desired outcomes, rather than generic case examples.
Delivery can be adapted across format, duration, pacing and support model, ensuring the programme fits the business and working patterns of your teams, not the other way round.
Action Learning Projects (ALPs) are a core element of Group Training and a key differentiator. Each cohort works on a real, organisation-specific improvement project, guided by a Master Black Belt coach to ensure learning is applied, tested and embedded.
The ALP process moves from clear scoping and alignment, through application of tools during the programme, to a structured review and consolidation phase. This approach accelerates learning, builds confidence and ensures outcomes extend beyond training into practical business impact.
Group Training is supported by the Game Change Bootcamp platform, designed for enterprise and global delivery. The platform brings learning, collaboration, coaching and reporting into a single environment, providing visibility for participants and sponsors alike.
Support can include project coaching, facilitated workshops, DMAIC tollgate reviews and coaching on demand. This ensures teams are supported throughout delivery while organisations retain clear oversight of progress, engagement and outcomes.
