Six Sigma Green Belt

What is a Six Sigma Green Belt?

Green Belt is a middle tier of Six Sigma certifications. Essentially, it’s an intermediate grade. A Green Belt knows a fair amount about Six Sigma methodology and can support a Black Belt in a major project or take on minor projects under supervision.

Qualities of a Green Belt

Six Sigma Green Belt practitioners are:

  • Analytical.
  • Educated in Six Sigma concepts.
  • Experienced in Six Sigma methodology.

What Do Six Sigma Green Belts Do?

A Six Sigma Green Belt typically works under the supervision of a Black Belt. Because they know a fair amount about Six Sigma methodology, they perform several semi-autonomous tasks, like:

  • Data collection
  • Data analysis
  • Running minor projects
  • Leading small teams.

Due to working under a Black Belt, a Green Belt typically doesn’t directly direct an entire project. Instead, they tend to assist in problem-solving efforts or take the lead on a portion of the project. This will often involve working with the data that Six Sigma projects rely on – including creating charts and tracking progress.

Many Green Belts are also working towards their Black Belt accreditation.

Time spent on Six Sigma projects

Many Green Belts won’t spend all of their work time on Six Sigma projects. Commonly, they’ll spend around 50% on these projects, although it could be as low as 25%.

How do Green Belts interact with Black Belts?

Because Green Belt is a lower-ranked certification than Black Belt, typically, you’ll have a Black Belt supervising and guiding you. For example, you might have a Black Belt running a Quality Management department while you lead a team within that department.

How Can a Six Sigma Green Belt Help Your Career?

The Six Sigma Green Belt certification tells prospective employers that you’re qualified to assist in running quality control and management programs. People with the required skill set are in high demand in the manufacturing and IT sectors.

How Do You Become a Six Sigma Green Belt?

To gain the certification, most people find it simplest to attend a Green Belt course and study for a few weeks afterward to ensure that the concepts stick. Then, once confident with the material, take an exam through one of the groups offering Green Belt certification. Note that there is a cost for the exam, although many course providers can offer a slight discount on it – depending on the certifying organization.
