Our LEAN Certification Program builds robust skills in LEAN Six Sigma, creating pride from delivering impact. Learn to uncover hidden potentials and systematically improve performance. And by doing so, champions not only build skills but also create tangible benefits from systematically reducing waste and variability.


Trainees advance their skills in up to five steps: (1) White Belt «Beginner», (2) Yellow Belt «Qualified», (3) Green Belt «Independent», (4) Black Belt «Expert», (5) Master Black Belt «Master Expert».

LEAN Skillbuilding Model


The training program establishes a Skill Pyramid to cascade knowledge from expert down to the frontline, involving people at all levels of the organization, including senior management.

Employing a Train-the-Trainer approach means that certified champions (“Belts”) move up one level in the pyramid, and by doing so, they become the trainers for people below them.

Each Black Belt supports 5 Green Belts, who support 5×5=25 Yellow Belts, who support 5x5x5=125 White Belts. At full leverage of the model, one Black Belt supports an organization of 200 people, of which 160 or 80% participate in the training program.

The Organizational Model


The Skill Pyramid is a professional support structure that allows people to connect with each other, exchange experiences, develop new ways of working and provide coaching support.


A customer service agent for example, who is working on a Yellow Belt project might get support from an accountant, who is a certified Green Belt and worked on a similar project before.

KUME Management provides the training courses to transfer skills and also the implementation assistance to build such professional support structure.

As Master Black Belts (MBB) we deliver the training and as interim manager, we lead the Project Management Office (PMO) to ensure the program contributes to the bottom line.

LEAN Course Program

The program consists of three parts: Training, Project, and Certification. During the Training Camp, participants learn about principles, tools, and techniques. Right after the training, they apply what they have learned in practical Improvement Projects to build real skills and create a tangible benefit for the company sponsoring the program. Champions present their work at the Certification Camp to get formally certified, learning additional skills and getting ready to train others. By doing so, they are setting in motion a “cascade of knowledge” to get their peers and direct reports on board.

The total time for learning, application, and validation takes 1 week for White Belt (LWB), 2 months for Yellow Belt (LYB), 6 months for Green Belt (LGB), and 12 months for Black Belt (LBB). During this period, participants must have enough time available to apply their skills and create the impact required for certification. The minimum fully dedicated time is 1 day for White Belt, 5 days for Yellow Belt, 30 days for Green Belt, and 100 days for Black Belt.

There are four roles to be assigned: Sponsor, Learner, Trainer, and Controller. The sponsor initiates the program, provides context and allocates resources. Learners invest their time, including some personal time, to read the material, complete exercises, and implement improvements. The Trainer leads learners through the program, providing theory, exercises, and coaching support. For Yellow Belt and above, the Controller validates financial benefits created from the improvement projects.

Certified champions are able to see and act upon opportunities where they could not before. By improving quality, efficiency, and flexibility they generate benefits from faster delivery and lower cost. Financial benefit from a single program is typical $0.5M to $1.5M per year, assuming a $50M addressable cost base and visible support from the top.

The program is self-funding, as most projects achieve full payback within the implementation period and typically deliver a financial benefit of 5 to 10x over cost (ROI) within the project lifecycle. To ensure effective skill transfer, the trainer must be able to spend quality time with each participant. We, therefore, limit the group size per trainer and session to 20 people, whereas the ideal size is half of the limit. The amount our clients spend on KUME Management´s support for training, project setup, coaching during the implementation period and certification is typically 1/5 to 1/10 of the delivered impact. It’s money well spent.
