Lean Six Sigma · Black Belt | León & Asociados LLC

The problem we solve

What it's for.

Some defects reappear even after the team already tried to fix them: they're chronic and cost money every month. As a Black Belt, we structure and support the project from start to finish, with measurement, statistics, and control that make the improvement stick. And today's Black Belt also orchestrates data: we support the analysis with Power BI and AI to find patterns faster.

Our founder at the test bench: coveralls, helmet, and gloves — Black Belt projects are measured at the machine, not in the boardroom.

Ideal for

This fits you if…

Operations with chronic problems

A costly defect keeps coming back despite past fixes.

Teams demanding rigor

FAQ

Frequently asked questions

A Black Belt project uses DMAIC with measurement, statistical analysis, and control for chronic, costly problems—not improvised solutions.

With your loss tree and cost Paretos: a few losses concentrate most of the money, and that is where the DMAIC aims. The project is born tied to a financial impact, not a hunch.

Yes. Our flagship project redesigned the rolling tooling (punch and plunger) of a metalworking plant: loss stratification, materials analysis, DOE with response surfaces, and Scrum as the execution framework — with material savings of 57% to 83% on the redesigned parts and freed-up workshop capacity. We bring that same rigor to your project.

No. We guide the project from start to finish with tools like A3, FMEA, DOE, and Minitab, explaining each step to the team.

Price is determined after an initial call, based on problem complexity and project scope.
