A quick guide to all the Lean Six Sigma belts and what they all mean...

Lean Six Sigma is a project management approach that combines the principles of Lean and Six Sigma to improve efficiency and reduce defects. Within the Lean Six Sigma framework, there are five levels of certification: white belt, yellow belt, green belt, black belt, and master black belt. Here's a look at the differences between these levels:

White belt

A Lean Six Sigma white belt is an introduction to the methodology. White belts have a basic understanding of the principles of Lean and Six Sigma and can contribute to improvement projects.

Yellow belt

A Lean Six Sigma yellow belt has a more in-depth understanding of the methodology and can lead small improvement projects. Yellow belts also have the skills to assist black belts in larger projects.

Green belt

A Lean Six Sigma green belt has a strong understanding of the methodology and can lead improvement projects. Green belts also have the skills to mentor and coach other team members.

Black belt

A Lean Six Sigma black belt is a subject matter expert in the methodology and can lead complex improvement projects. Black belts also have the skills to mentor and coach other team members and to teach Lean Six Sigma to others.

Master black belt

A Lean Six Sigma master black belt is a highly experienced subject matter expert who has a deep understanding of the methodology. Master black belts have the skills to lead and mentor other black belts and to develop and implement Lean Six Sigma strategies at the organizational level.

Overall, the difference between the five levels of Lean Six Sigma certification is the depth of understanding and the level of responsibility in leading improvement projects. White belts have a basic understanding, yellow belts have a more in-depth understanding, green belts can lead improvement projects, black belts are subject matter experts who can lead complex projects and mentor and coach other team members, and master black belts are highly experienced subject matter experts who can lead and mentor other black belts and develop and implement Lean Six Sigma strategies at the organizational level.
