Greenbelt and Blackbelt Certification Criteria

We certify Six Sigma Greenbelts and Blackbelts based on the application of Six Sigma methods and tools to a real project in your business. Here's how it works:

• Complete a project using Six Sigma methods and tools.
• Submit a case study of the project along with your certification fee.
• We will review the case study, provide feedback and coaching and certify you when the case study meets the requirements.
• Greenbelt Certification - $995. Requires 1 project.
• Blackbelt Certification - $1,495. Requires two projects, a Green Belt level project and a more advanced project using the tools of Design for Six Sigma.

Case Study Requirements

Use the Green Belt Checklist (Click Here) to verify that you have everything required for submission.

1. Please remove all company names and substitute industry names. (e.g., Sam's Printing becomes Printing.)

2. Provide a one-two page written description of the case study
   • How initiated?
   • Measurements used?
   • Baseline performance
   • Targets for improvement?
   • Team formation and duration
   • Tools used
   • Results of improved performance

3. Show the before and after state of the process using the Six Sigma tools (see below).

4. Send the case study in MS Word (text), Excel (data and charts), and PDF files preferably with one printed copy of the example with all supporting data. If your case study was done with tools other than the QI Macros, please send the files and raw data.

5. Problem Solving
   • Define and Measure
     (control chart and pareto charts or histograms)
     
   • 
     The pareto chart should be a direct descendant of the control chart.
     
     If you're counting defects on the control chart, the pareto chart should analyze the types of defects, not the size, width or weight of the defective samples.
     
     If you're measuring billing adjustments in dollars, the pareto chart should show types of adjustments in dollars.
     
     If you're measuring time, weight, length, diameter, etc., the histogram should show the variation in the measurements.
     
   • Analyze
     (Ishikawa and solutions selected)
     
     The problem statement in the head of the fish should be directly related to the "big bar" on the pareto chart created in the previous step.
     
     If, for some reason you choose to use the tiny third bar instead, you'd better have a very good reason (like you've already analyzed bars one and two). Otherwise it looks like you're working backward from your gut-feel solution to create the data to justify your improvement story.
     
     
   • Improve
     (Control chart, pareto charts, histograms)
     
     
     
     These should be continuations of the control chart, pareto charts or histograms from the define step and they'd better show improvement. Otherwise, you didn't find and fix the real root cause.
     
   • Control
     (Improved flowchart with charts for monitoring stability and capability)
     
     
     
     The control chart used to monitor the process in the future should use the same data as the control chart used in the define and improve steps.
     
     

If your project is a blackbelt project, include one of the DFSS Tools.

1. DFSS (QFD House of Quality)
   
   
   

2. Design of Experiments
   

   

3. Measurement Systems Analysis - Gage R&R
