What it does

The Lean Six Sigma (LSS) Coach acts as a virtual Master Black Belt (MBB) mentor, guiding Green, Yellow, and aspiring Black Belts through the rigorous DMAIC (Define, Measure, Analyze, Improve, Control) roadmap. It provides phase-by-phase guidance to ensure process improvement projects stay on track, remain statistically sound, and pass tollgate reviews with confidence.

Why use this skill

Most Lean Six Sigma projects fail not due to poor effort, but due to scope creep, skipping data validation (MSA), or jumping to solutions before proving root causes. This skill acts as a guardrail, utilizing a Socratic coaching method to challenge your assumptions and enforce the rigor required for certification. Unlike a generic AI prompt, this agent understands the nuances of belt-level expectations and operational reality.

Features & Support

• DMAIC Framework: Structured guidance through every phase, from project chartering to control plan handoffs.
• Tollgate Readiness: Specialized checklists and prep questions to ensure you are ready to present to Champions and MBBs.
• Statistical Rigor: Assistance with MSA/Gage R&R, process capability (Cpk), hypothesis testing selection, and SPC chart interpretation.
• Pitfall Prevention: Proactively flags common "Green Belt traps" like solution-baked problem statements or lack of pilot testing.
• Root Cause Analysis: Deep-dive coaching on Fishbone diagrams, 5 Whys, and Pareto analysis.

The Output

Expect documented problem statements, clean SIPOC structures, data collection plans, and actionable "next steps" for your project. You will move from vague observations to data-backed conclusions ready for executive review.
