Six Sigma Certification is a valuable business asset which serves as a tool to help you and your workforce optimize your supply chain and other business processes. Six Sigma training is involved and intense and demands a high level of rigor and commitment. It also typically costs money to complete. 

Where to Start Looking

Some companies will provide Six Sigma training to their employees, so if you're looking for free Six Sigma training, start by checking with your employer. 

Next, try the American Society for Quality. They can point you to all things legitimate in the Six Sigma world. Also, the Six Sigma Digest can provide learning resources, including free ones. And for the very basics of Six Sigma, you can check out the Aveta Business Institute's free white belt training. For a self-study option that offers free materials and information on how to get certified, check The Council for Six Sigma Certification.

What Is Six Sigma?

Motorola implemented the concept of Six Sigma in the mid-1980s as a way to seek process improvements in its manufacturing operations. Since then, the term has become synonymous with process optimization.

In a nutshell, Six Sigma projects are disciplined, data-driven and designed to improve processes by identifying and removing the causes of defects or errors and minimizing variability. Six Sigma projects are usually led by professionals trained (and typically certified) in Six Sigma techniques. 

A Free Six Sigma Primer

The Six Sigma vocabulary can sometimes be confusing, so here’s an overview to get you started. Understanding these terms will help you as you look through free course offerings so that you'll have a better idea of what these courses are really offering you.

Why Is It Called “Six Sigma?”

The term Six Sigma comes from the statistical principle that states: If you start at your process’ mean value and eliminate defects within six standard deviations of the mean and the nearest specification limit, you’ll virtually eliminate all defects or errors. 

If you’re not a statistician, think of Six Sigma as looking at a bell curve and eliminating the errors within the thick chunk of the bell. 

Executive Leadership

Within any Six Sigma project, you’ll want and need executive leadership. This role can include the CEO or other top management. They are responsible for setting up a vision for a Six Sigma implementation. One important aspect of having executive leadership is the buy-in aspect of it from the employees involved. 

If you want a project to succeed, it’s critical that those in an organization understand why it’s important, and to whom it’s important.


The Champion is the person in an organization who 'champions' a Six Sigma project, like a senior manager who ensures that it’s properly resourced and uses their authority to overcome organizational barriers. The champion sits a level below the Executive Leadership.

Master Black Belt

The Master Black Belt is an expert with extensive experience and technical expertise in all aspects of Six Sigma. The Master Black Belt has responsibility for selecting, training and mentoring black belts within an organization. They’ll also ensure the Six Sigma program standards are maintained.

Black Belt

A Black Belt is a full-time professional and team leader responsible for the operation and outcome of a Six Sigma project. Black Belt training courses involve a month or more of classroom training — with a study focus on methods, statistical tools, and team skills. 

Black Belt training courses also require a completed Six Sigma project. Certified Six Sigma Black Belt qualification courses are offered by the American Society for Quality (ASQ) and other organizations.

Green Belt

A Green Belt has been trained in Six Sigma methodology and participates in projects as part of their full-time job. They may either work as part of a team, led by a Black Belt, or lead smaller projects, with a Black Belt acting as a mentor.

Project Sponsor

The Project Sponsor is a manager who can sign off on resources, defines objectives and evaluates outcomes. The Project Sponsor is sometimes the Champion or Executive Leadership.

Big Y and Little y

The high-level objective that a Six Sigma project seeks to improve is known as the Big Y . The Big Y is often used to generate little y operational objectives that need to be improved to hit the Big Y target.


The Six Sigma process has five main steps: Define, Measure, Analyze, Improve and Control, which cover the following areas and activities:


  • Define the customer and their expectations
  • Define the impacted business processes
  • Define the project boundaries
  • Create a process map
  • Define metrics, including Big Y and little y's
  • Form a project team
  • Develop a project charter


  • Gather data and measure the existing processes


  • Analyze the gathered data
  • Identify the gaps between existing and desired performance
  • Identify sources of variation
  • Decide on the processes to be improved


  • Propose solutions
  • Carry out pilot studies, test and evaluate the proposed solutions
  • Develop an implementation plan


  • Implement processes to ensure sustainable improvements
  • Develop procedures, control plans and train staff
