01 — Programs
Our Yellow, Green and Black Belt programs combine structured learning with practical tools, knowledge assessment and real-world application — creating a progressive pathway from improvement awareness to advanced problem-solving and leadership.
See it. Understand it. Improve it.
Build the foundations of Lean Six Sigma. Learn to recognize waste, understand processes, participate in structured problem solving and use practical improvement tools.
Analyze it. Solve it. Lead it.
Develop the capability to lead DMAIC improvement projects, measure performance, validate root causes, make evidence-based decisions and sustain measurable results.
Solve complexity. Coach others. Build capability.
Master advanced problem solving, statistical analysis and experimentation while developing the facilitation and leadership skills required to tackle complex, cross-functional improvement challenges.
02 — How it works
It's a working improvement system.
Assess your existing knowledge and identify the right starting point. Your current assessment already distinguishes Yellow-, Green- and Black-Belt-level knowledge and recommends a starting level.
Learn through structured, interactive Belt curricula designed to build capability progressively.
Practice with exercises, worked examples and knowledge checks that reinforce the methods before you apply them.
Apply the methods using the integrated Operational Excellence Workbook — the same tools your team will use on the floor.
Lead improvement against an actual operational problem, building confidence and ownership as you go.
Demonstrate capability through assessment and project results that show real, sustained impact.
Because knowing the tools isn't the same as knowing how to use them.

04 — About

Led by Patsy Morrow, a Lean Six Sigma Master Black Belt with deep experience across manufacturing and healthcare, we deliver Yellow, Green, and Black Belt certification programs aligned to the IASSC Body of Knowledge — alongside Lean Leadership, Quality as Organizational Strategy, and our Operational Excellence Toolkit.
We don't lecture from the front of the room. We work shoulder to shoulder with your teams on live problems in your own processes, so the capability stays with you long after we've gone.
