Understanding Lean Six Sigma and Belts: A Quick Note

If you’re interested in learning how to make improvements within any business role and deliver sustainable savings, it’s no surprise that you’ve landed on this page.

Lean thinking and six sigma processes are becoming increasingly important in an economy geared towards doing more with less.

Green Belts are key players in this thriving, streamlined business environment.

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 article, “What is Lean Six Sigma?” to delve deeply into the origin and outline of these process improvement methodologies.

For the purpose of this article, here is 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 are six sigma belts?

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

You can get a full outline of the different belt levels and their roles within lean six sigma by reading our article, Understanding Lean Six Sigma Belts”.

What is the Difference Between Lean Six Sigma and Six Sigma Green Belt?

Some certifications focus solely on the six sigma methodology and therefore name their credentials simply “six sigma” rather than “lean six sigma”.

Other programmes and certifications, such as our lean six sigma green belt, combine both approaches.

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