Six Sigma Green Belt Training 


Green Belt training focuses on the principles of variation reduction and Lean Manufacturing. The goal is to 1) control the process variation, then 2) shift the process performance (mean) to a desired target 

Green Belts 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 teams and have a Black Belt serve as a mentor.

Working through this material will not only prepare you for a Green Belt project and certification but set the foundation as a Black Belt and beyond. 

Green Belt Certification Topics

Green Belt Training and 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 introduced to the basic non-normal distributions and hypothesis testing.

All of these topics, and more, are covered within this website. Active subscribers will be provided login credentials to access all the content within the site.

  • Basic Statistics and Quality Tools
  • Quality Gurus
  • Statistical Process Control
  • Process Mapping
  • Value Stream Mapping
  • Measurement System Analysis
  • Capability Study
  • Cause and Effect Matrix
  • FMEA (Failure Mode Effects Analysis)
  • Multivariate Analysis
  • Central Limit Theorem and Confidence Intervals
  • SPC (Cpk, Cp, Ppk, Pp)
  • Transactional Process Improvement
  • 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)
  • Key Financial Metrics

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 >180 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.

GB's usually are not asked to perform hypothesis testing of non-parametric data. Typically, one will work together with a BB or MBB to go over the data, review assumptions, possibly transform the data, or apply non-parametric analysis together.
