AI-Enabled Lean Six Sigma: Transforming Process Excellence with AI and Automation

AI-Enabled Lean Six Sigma AI-Driven Process Excellence: Essential Tools and Methods for the AI-Augmented Belt Lean Six Sigma has endured for forty years because it works. But the operating environment it was designed for has changed. Data that was once scarce now flows in torrents from IoT sensors, ERP systems, and customer feedback channels. Analysis that once took weeks must now take hours. Processes that once involved a handful of variables now generate hundreds. The methodology is sound. The tools have caught up. In this concise introduction, Master Black Belt and MBA Jim Cen maps the convergence of AI and Lean Six Sigma across every DMAIC phase. You will learn: Define — How NLP sentiment analysis processes 100% of customer feedback instead of 5% survey response rates. Measure — How process mining reconstructs the as-is process from event logs, surfacing 14,000 path variants that no interview will ever reveal. Analyze — How ML feature selection and SHAP values scan hundreds of variables to find root causes — including three-factor interactions that fishbone diagrams miss. Improve — How digital twins, reinforcement learning, and AI-enhanced FMEA compress the test-and-learn cycle. Control — How intelligent process control, predictive maintenance, and model drift monitoring upgrade SPC from periodic review to 24/7 early warning. Toolkit — A four-layer tool pyramid from free entry points (Claude, ChatGPT) to specialist platforms, plus a 30-day startup plan. Six AI technologies, one methodology. This book covers machine learning, natural language processing, computer vision, predictive analytics, process mining, and agentic AI with multi-agent orchestration — including how retrieval-augmented generation (RAG) grounds AI responses in your actual control plans, FMEA libraries, and SOPs. Written for four readers: Practicing Belts are tired of wrangling data out of disconnected systems before real analysis can begin Quality Leaders who need a defensible AI roadmap — not vendor hype — for their CoE Operations Leaders who want faster results without replacing the people who drive improvement Industry Professionals in manufacturing, healthcare, financial services, and logistics who see the data revolution coming and want a concrete starting point Every concept is explained in full. Every chapter contains a practical example. Code snippets are intentionally short and aimed at non-programmers. No data science degree required — just curiosity and a working knowledge of DMAIC. The professional edition expands to 19 chapters with 53 diagrams, 190 data tables, full Python code, 35 ready-to-use prompts, and multi-industry case studies. This concise book gives you the map; the professional edition provides the full terrain. Author Jim Cen, Lean Six Sigma Master Black Belt, MBA
