Lean Six Sigma Yellow Belt Certification


Lean Six Sigma Yellow Belt Certified (LYBC)™

2023 Edition

A Lean Six Sigma Yellow Belt certified professional works as subject matter expert within their company.  They assist Green Belts and Black Belts as they work to remove inefficiency and waste from the organization.  “Lean” means continuously improving towards the ideal and achieving the shortest possible cycle time through the tireless reduction of waste.  It is focused on eliminating waste in all processes.  It is about expanding capacity by reducing costs and shortening cycle times.

 Anyone within an organization can be certified as a Lean Yellow Belt, from call center employees to the CEO of the company.  The “level” of certification just depends on the task that person will be performing within the Six Sigma project.  If they are leading the project they may be certified at the Green Belt or Black Belt level.  It they are only working in an advisory position and assisting the Black Belt with internal process-knowledge, the Lean Yellow Belt is the best six sigma certification.

The role of a Lean Six Sigma Yellow Belt is fairly small.  Lean Yellow Belts generally continue to work on their normal job tasks, only stopping to assist on the project when it’s requested.

The Lean Six Sigma Yellow Belt Certified (LYBC) program includes the Management and Strategy Institute’s exclusive YBsim™ simulation.  This Six Sigma simulation walks you through the role of a Lean Six Sigma Yellow Belt so you’ll gain valuable experience.  In this Six Sigma simulation, you’ll look at a simulated company working on a project.  You’ll look at the company’s current Sigma level and gain an understanding of team roles as the project charter is developed.
