Six Sigma Green Belt (SSGB) Certification


Green Belts focus on principles of variation reduction, Lean Manufacturing and have a basic understanding of statistical analysis. Their goal are both shifting the performance to a desired target and reducing the variation of a process.

They typically support Black Belts and are not always employed as full-time Green Belts. Green Belts often have a full-time role in the company and participate in Six Sigma projects as directed. However, Green Belts can lead their own teams and have a Black Belt serve as a mentor.
