Lean Six Sigma Black Belt | Green Belt Course Creator

NEW: Customizable Six Sigma Green Belt course, self-paced or instructor-led, with a Contact the Instructor button in every topic. See my Projects below for course and consulting packages with set prices. I was at Motorola when Six Sigma was created there, became a Black Belt, and I've used it ever since — first in high tech manufacturing, then in financial services, and now as a trainer and consultant. I've also worked side by side with Toyota on Lean. What I can do for you: • Process improvement — DMAIC projects, root-cause analysis, cutting rework and cycle time • SPC and quality — control charts, capability (Cp/Cpk), Gage R&R • Data analysis — turning messy operational data into clear findings and next steps • Training — Green Belt courses, interactive e-learning, exam-prep question banks, assessments • Reports and presentations — DMAIC deliverables, executive summaries, training decks How I work: plain language, practical recommendations, and deliverables you can use right away. Tell me what you're trying to fix. I'll give you an honest answer on whether I can help.
