Training Programs


Focused to meet your industry needs!

Live Instruction | Real-Life Projects | Experienced Instructors 



A Go-Lean-Six Lean/DMAIC certificate validates your knowledge of and experience with Lean/ DMAIC principles.  

The Go-Lean-Six certificate program is focused on creating a standard for continuous improvement through a robust body of knowledge that is primarily based on Toyota Production System’s Lean Transformation Model and the Lean Production System.  In addition, it adds the problem-solving components of Motorola’s DMAIC (Design-Measure-Analyze-Improve-Control) and Six Sigma for Quality Excellence. 

Our goal is to support a community of continuous improvement practitioners and leaders through training and coaching and to improve the workforce. 

Our Lean/DMAIC Yellow and Green Belt Certificate training programs focus on mastering the fundamentals of Lean from a tactical perspective with a robust understanding of the DMAIC problem-solving methodology. The Green Belt Certificate moves from basic understanding of the principles and tools in the Yellow Belt to applied experience by the completion of a project in the Green Belt program. 

The Lean/DMAIC Black Belt furthers the knowledge of the tactical and applied experience in Yellow and Green Belt by introducing Leadership principles and advanced Lean Tools and Methods.

The Lean/DMAIC Yellow Belt operates in support of process problem solving and projects.  They are key team members, often taking leadership roles in problem- solving. 

The Lean/DMAIC Green Belt operates in support of or under the supervision of a Black Belt.  They analyze and solve process problems and are involved in process improvement projects. A Green Belt often facilitates Improvement Teams. They understand the Lean Principles and the Define, Measure, Analyze, Improve and Control (DMAIC) and can use them for problem-solving.  They help to identify and drive out waste from processes and work on teams to help lead them.

A Lean/DMAIC Black Belt has a thorough understanding of all aspects of the Lean principles and of the define, measure, analyze, improve and control (DMAIC) model.  They can identify non-value-added elements, leading teams and activities and are able to identify the need for and apply Lean/Six Sigma quality tools for problem-solving. A trained Lean Black Belt can see waste across integrated processes and can train others in the Lean principles.
