Six Sigma Certification - Project Requirements

Green Belt certification is based on a completed project, not training.

Opportunity is missed by most people because it is dressed in overalls and looks like work."

- Henry Ford

To gain our Green Belt certification, you will need to apply the tools to an actual business problem.

Green Belt Projects

  • Green Belt projects can be focused on reducing either defects or deviation. Follow checklist below.
  • The cost for initial project is $250 and covers our time to review your project.
  • If your project passes review, you will receive an email with a link to order your certification using a credit card. The cost for certification is an additional $250.
    You may also purchase QIMacros for $20 off the usual price.
  • If your project does not pass review, you will receive an email with feedback on what to fix and you may be referred back to the requirements page. You can purchase an additional review ($250)..

Green Belt Submission Criteria:

To make certification affordable, there are stringent requirements for submitting a project for certification:

  1. All projects must be submitted as a single Excel workbook using charts and templates.
  2. All data, charts and templates must be included in the Excel workbook.
  3. All charts and diagrams must be created with the QI Macros and Excel.
  4. We will not accept Word or PowerPoint files, or pictures of charts, or projects without raw data.
  5. Excel worksheets must be in the order shown below:

    green belt project criteria

    There must be worksheets for raw data (before and after improvement).
    Include PivotTables if used in the analysis

    Histograms can be used in place of Pareto Charts when solving problems of deviation.

Green Belt Project Review Process:

  1. Does Your Project Meet the Submission Criteria?
    • If your first project submission does not meet the above criteria it will be returned with a referral back to this page.
    • If your second project submission does not meet these criteria it will result in disqualification from this certification offer.
  2. Does Your Project Apply Lean or Six Sigma Methods and Result in Process Improvement?
    • If yes, then we will send you a congratulations email with a link to purchase your certification for $250.
    • If your project does not pass but shows promise, I'll suggest that you either revise and resubmit your project or consider coaching for an hourly fee of $250.

Green Belt Project Checklist

Here's what we consider to be the key requirements for a Green Belt Project (defects or deviation). Draw all charts with QI Macros for Excel.

Defects Deviation (Variation)
Step Project begins with data about the problem (defects or deviation), not by trying to retrofit a Six Sigma project to some accidental, knee-jerk success.
You must submit your raw data with your project.
1. PivotTable of defects from a list or database (optional)
2.

Control Chart Excel for Six Sigma

Analyze defects, mistakes and costs over time.
Use time-series data (the X axis should use dates or times).

Tarpits: Do not use category data in a control chart.
Use times series data.

Control Chart Excel for Six Sigma

Analyze deviation of part dimensions or cycle time over time.
Use time-series data not category data.

Is the Process Stable?
If not, analyze root causes of out-of-control points to stabilize the process before improvement
(see Root Causes below)

3.

Pareto Chart

Analyze Defect Categories using defect types from Control Chart data (above).
Use category data (e.g., defect types) not time series data.
There may be two levels of pareto charts.
There may be more than one "Big Bar" resulting in more than one fishbone.

Tarpit: Your Pareto chart must reflect the data used in the control chart. You can't just string charts together and call it a project.

Histogram Excel

Analyze Capability using Control Chart data (above)

Is the process capable?
(Cp > 1.33, Cpk > 1.33)
If not, analyze root causes.

4.

Ishikawa Diagram Excel for Six Sigma

Analyze Root Causes of Defects
Head of the Fish is the "Big Bar" on the Pareto Chart.
Root causes must be the last bone in any chain.
Circle the Root Causes.

Tarpits: The problem statement is not directly related to the "big bar" on the Pareto Chart or you try to combine many bars into one analysis. You will end up with a whalebone diagram.

Broken logic. Check your logic by going back up the chain:
C causes B causes A.

Solutions on the fishbone.
These go in the Courntermasures matrix.

5.

Countermeasures Matrix Excel for Six Sigma

Countermeasures and Action Plan for Improvement.
Copy the Problem Statement and Root Causes from the Fishbone Diagram into the Countermeasures Matrix.

Countermeasures and Action Plan for Improvement.

 

Countermeasures describe clear methods for changing the process to prevent defects and deviation, not detect or correct them after they occur. Include cost savings from implementing these changes.

Countermeasures should not involve:

  • adding more people (especially inspectors) because you don't need more people, you need less rework and waste.
  • spending more money (process changes are often procedural not mechanical).
  • automating the detection and correction process (i.e., inspection).
  • more training (it's not a people problem, it's a process problem).

Project Coaching

If you want to "pick my brain" about your project or need some help getting started, we offer coaching for $250 per hour. Coaching is only available for those who have completed the Yellow Belt training and certification.

But Jay, I don't have a job. How am I going to do a project?

Easy. Go to a local business meeting.Kiwanis, Rotary and other groups meet weekly or monthly. Introduce yourself to various business owners. Tell each one that you want to get your Green Belt in Lean Six Sigma and volunteer to use your skills to help his or her company fix some seemingly unsolvable problem that involves defects or deviation, waste or rework. Ask them what keeps them up at night? What problem costs them the most money? For example, a printer that reprints too many jobs; a restaurant that wastes too much food. The company probably needs to have 10 or more employees and some data about their problem to be a viable candidate for Lean Six Sigma.

Set up a day to gather their data, turn it into a control chart, Pareto and/or histogram and develop a problem statement for the fishbone. Present these charts to the owner and ask for a few hours to do root cause analysis with the people who work in that area. Analyze the root causes using "5 Whys." Avoid the training, time or money traps of root cause analysis. Verify the root causes and identify ways to mistake-proof the process so that it is impossible to continue making the error. Show the results and ask for permission to have the team implement their improvements. Track the results using the control chart, Pareto and/or histogram. This should give you what you need.

Who knows. This might even turn into a job or consulting career. Volunteer to do it for free with minimal involvement of their employees, just a SWAT team convened for root cause analysis and implementation.
