Lean and Six Sigma

First things First: What is Lean Six Sigma?

To understand what a green belt does, you need a clear picture of lean, six sigma, and how they are combined as a dynamic duo.

If you have a little time, why not read our detailed “What is Lean Six Sigma?” article to delve deeply into the origin and outline of these process improvement methodologies.

For the purpose of this article, here’s our shortest description of lean six sigma:

  • Lean is geared towards identifying and eliminating waste.
  • Six Sigma focuses on statistics to reduce variations and defects in a process.
  • Both are effective as standalone methodologies. When used together, they are transformational.

What does “Green Belt” mean?

The ‘belt’ system applies mostly to six sigma, and it’s a way of structuring the level of knowledge, input, and responsibility of each six sigma practitioner.

Green Belts are instrumental to the progression of any process improvement project, and work closely with Black Belts to achieve significant improvements and savings.

Is there a difference between a “Lean Six Sigma Green Belt” and a “Six Sigma Green Belt”?

Some certifications focus solely on the six sigma methodology. Our Lean Six Sigma Green Belt combines both approaches.

We have chosen this method of learning, as it gives each practitioner a fully rounded knowledge of how to transform a business environment.

What does a Six Sigma Green Belt do?

A Green Belt is someone who is actively involved in process improvement projects, often under the guidance of a Black Belt practitioner.

Green Belts work towards solutions and are key contributors to the progress and success of any process improvement project.
