Train your people, or bring in ours
Some teams want the capability in-house. Others need the process fixed this quarter. We do both, and we'll tell you honestly which one fits.
Training & certification
Build the skill inside your team. White through Black Belt, self-paced or live, every belt ending in a mentor-reviewed capstone project.

Bring in a Design for Lean Black Belt to lead a DMAIC project on your process directly — with a fixed-scope plan, not open-ended hourly billing.

Most certification programs teach theory. We teach you to run a real improvement project, with a mentor checking your work, so the certification actually means something.
Project-based, not slide-based
Every belt ends with a real capstone project on your own process — not a multiple-choice exam. You leave with a documented win, not just a badge.
Mentored by practitioners
Your capstone is reviewed by a certified Master Black Belt with real operating experience — not an automated quiz grader.
Aligned to a real body of knowledge
Curriculum is mapped to the American Society for Quality Lean Six Sigma Body of Knowledge, so what you learn transfers cleanly to any organization.

Trusted by people doing the actual work
"The capstone requirement is what sold me. I didn't just learn DMAIC — I actually cut our changeover time by 22% and could prove it."
"I've done corporate training that felt like a checkbox. This was the opposite — my mentor pushed back on my control plan until it actually held up."
"We put four people through Yellow Belt as a trial. All four are now running their own small improvement projects. Green Belt cohort is next."
