Six Sigma Green Belt (SSGB) Certification


Green Belts focus on principles of variation reduction, Lean Manufacturing and should have a basic understanding of statistics. Their goals 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. They often have a full-time role in the company and participate in Six Sigma projects as needed. However, Green Belts can lead their own teams and have a Black Belt serve as a mentor.

Green Belt Certification Topics

Green Belt Certification usually requires knowledge or execution of the tools shown below. At this stage, similar to Yellow Belts, they generally are not taught to create and manage a DOE. They are versed in basic non-normal distributions and hypothesis testing.

  • Basic Statistics and Quality Tools
  • Statistical Process Control
  • Process Mapping
  • Measurement System Analysis
  • Capability Study
  • Cause and Effect Matrix
  • FMEA (Failure Mode Effects Analysis)
  • Multivariate Analysis
  • Central Limit Theorem and Confidence Intervals
  • Transactional Process Improvement
  • Hypothesis Testing
  • Non-Normal Hypothesis Testing
  • T Tests
  • One Way ANOVA and Chi Squared Tests
  • Correlation and Regression
  • Control Plan
  • SMED (Quick Changeover)
  • Kaizen Event (Focused Area Improvement Event)
  • Poke Yoke (Error Proofing)

Typical Green Belt certification requirements

Green Belt certifications programs are less rigorous than Black Belt program but more than Yellow Belt and usually consist of:

  • 40 hours – 160 hours of coursework
  • Participation in at least one Six Sigma project
  • Mentoring of other Green Belts, White Belts, or Yellow Belts
  • Evidence using project management tools
  • Evidence showing basic application of statistics
  • Evidence of understanding the Lean principles
  • Written examination

There are also over 100 example certification problems available for subscribers of this site. Many of the problems have further explanations along with additional developmental material that can be found within this site.

GB's should possess an understanding of basic statistics and hypothesis testing with normal and non-normal distributions.
