Lean Six Sigma Master

Problem It Solves

Enterprise quality projects often get stuck when goals are vague, baseline data is weak, root causes scatter, and improvements fail to stick. Lean Six Sigma Master structures LSS work into executable stage tasks, helping teams close the loop from problem definition and measurement baseline to root cause analysis, improvement, and control without relying only on intuition.

How It Works

The skill centers on two methods:
- DMAIC: for optimizing existing processes, running Define, Measure, Analyze, Improve, and Control.
- DMADV: for new process or product design, focusing on design requirements, capability risk, design alternatives, and verification.

Each stage includes concrete actions: definition produces a problem statement, project charter, and SIPOC; measurement covers KPIs, MSA, and Cp/Cpk; analysis uses fishbone diagrams, 5 Why, hypothesis testing, and regression; improvement applies FMEA, cost-benefit review, and PDCA; control establishes SOPs, control charts, and alerting. It also indexes assets/templates/, references/, and scripts/generate_plan.py for standardized project planning.

Scope and Cautions

It fits engineering or operations projects with clear processes, metrics, or quality problems. Use DMAIC for improving existing processes and DMADV for new design. Tool choices and case references still need adaptation to the business context.
