Six Sigma Green Belt
The 6 σ green belt is one step below the black belt. These individuals work part time on improvement projects. It is estimated that between 3%-10% of their time is dedicated to improvement project in a calendar year.
Unlike black belts who are normally dedicated to improvement projects, the six sigma green belt maintains a normal workload in addition to their project responsibilities.
Six Sigma Green Belt Training
Green belts typically receive two weeks of training. The initial week is the usually the same as received in yellow belt training. The second week focuses more upon the measure and analyze phases of the DMAIC process, and the students receive in depth training on statistical analysis. Read more about the yellow belt training by clicking on the link.
After learning the basics of DMAIC in week one, students will learn how to use various analysis tools such as:
- Gage Repeatability and Reproducibility (GR&R)
- Process Capability Studies
- Descriptive Statistics
- Graphical Analysis
- Regression Analysis
Of course, there is much more than listed above. Not only do students learn how to use the tools, more importantly, they learn to analyze the results! That's what six sigma is about, using data to make good decisions.
Six Sigma Green Belt Responsibilities
A green belt is expected to not only lead process specific projects, but also serves as a team member to other higher level improvement opportunities. They make project suggestions and champion the six sigma program within their work area.
Championing the cause is one overlooked, yet highly important responsibility of the green belt. Not only should they communicate project progress with their co-workers, they should also build excitement toward all improvement projects. They should also be aware of those who take greater interest in the improvement opportunities, as those individuals may be outstanding candidates for green or yellow belts.
In practice, all your company's belts should build excitement for the entire six sigma program. They should all become walking advertisements for process improvement.
Green Belt FAQS
How many do we need?
Typically an organization with a strong six sigma program has trained about 1 per 20 employees.
Why so many?
Because they primarily focus upon a single process, it is wise to have green belts spread throughout your organization.
Should we promote them to black belts?
Yes, select the higher performing ones and provide the necessary training to allow them to become black belts.
