A World of Difference Through Process Improvement

Our Lean Six Sigma training leads to certification “belts.”

These belts signify experience.


Black Belt

A Black Belt has expert knowledge and skills related to the DMAIC methodology, Lean methods, and team leadership. Black Belts should be able to lead teams in executing Lean Six Sigma projects. Black Belts may also conduct Lean Six Sigma training and act as coaches and mentors to other Belts-in-training. Your Black Belts will lead problem-solving projects.


Green Belt

A Green Belt has strong knowledge and skills related to the DMAIC methodology and Lean methods, but typically does not have experience with advanced statistical tools such as design of experiments (DOE). Green Belts may lead simple projects under the guidance of a Black Belt or may work as a team member on a large project team. Your Green Belts will assist with data collection and analysis for Black Belt projects.


Yellow Belt

A Yellow Belt is trained in the general Lean Six Sigma concepts and basic tools. A company deploying Lean Six Sigma may choose to designate project team members as Yellow Belts after completing a required training course, or may use the designation for employees responsible for data collection for a Green Belt or Black Belt project. The Yellow Belt body of knowledge is defined quite differently by different organizations. In some cases, it may represent only the most basic concepts and language of Six Sigma, with an overview of the DMAIC process. In other cases, Yellow Belts are trained in a more complete set of basic tools. Your Yellow Belts will review process improvements that support the project.



A project Champion is a high-ranking manager who will work with a Black Belt to ensure that barriers to project success are removed and the project team has the organizational support it needs to be effective. Champions are not expected to be experts in the statistical tools or even experts in the project’s specific subject matter. Instead, they must possess a breadth of organizational knowledge to ensure that the project team’s work is aligned with the organization’s strategic objectives and interfaces effectively across the organization. Your Champions will identify resources and remove roadblocks.
