Lean Six Sigma Training Courses – Belts and Certification Levels

This training is designed for any team or group of professionals from the same organization who play a role in, or whose work relates to, its subject. The content is tailored to the group’s context and experience level, so the whole team builds a shared capability it can apply immediately.

Lean Six Sigma follows a structured certification path, with each belt building on the knowledge and capabilities developed in the previous level. The right starting point depends on your team’s current experience and the role it will play in continuous improvement. Our specialists can help assess your needs and recommend the most appropriate training path for your team and organization.

Lean focuses on eliminating waste and improving flow, while Six Sigma focuses on reducing process variation and defects through data-driven analysis and the DMAIC methodology. Lean Six Sigma combines both approaches to improve flow, reduce variation, and deliver more efficient, predictable, and higher-quality processes.

All Kaizen Institute Lean Six Sigma programs combine practical exercises and simulations with hands-on learning. From Yellow Belt onwards, participants apply the methodology through real improvement projects in their own organizations. This ensures capability is built through practical application and translated into measurable business results.

Yes. All programs include Lean Six Sigma certification upon successful completion. Certification requires participants to pass a certification exam, while Yellow Belt and above also require the successful completion of a practical improvement project. This combination of theoretical assessment and real-world application ensures participants develop both the knowledge and practical capability expected at each certification level.

Results depend on the certification level and the improvement opportunities addressed, but organizations typically achieve measurable improvements in quality, productivity, lead time, process efficiency, and operational costs. White and Yellow Belt programs build the knowledge, engagement, and practical skills needed to support continuous improvement. Green and Black Belts lead improvement projects that deliver measurable business results, while Master Black Belts develop the organizational capability, governance, and culture needed to sustain and scale those results over time.

Yes. The training is delivered in-company and tailored to your organization’s processes, practices, and typical challenges. The program is aligned with your organization’s reality, priorities, and team structures, enabling teams to apply the concepts and methodologies directly to their work environment.

Yes. The in-company format is designed to train teams, not individuals. Typically, each group includes up to 12 participants to maximize interaction, practical application, and coaching effectiveness. However, programs can scale across multiple groups, departments, or sites using parallel cohorts or scaling methods adapted to large organizations.
