Lean Sigma: A Practitioner’s Guide

The Practical, Easy-to-Use Guide to Lean Sigma Problem-Solving

Lean Sigma delivers results—if you use the right tools and techniques. In Lean Sigma: A Practitioner’s Guide, Dr. Ian Wedgwood captures best-practice Lean Sigma experience from multiple projects and industries, helping any professional identify the solution that will work best—and implement it.

Wedgwood’s exclusive "project roadmaps" present the fastest, most effective route to solving a wide range of problems—and explain why those solutions make sense. His "discovery roadmaps" help you identify potential Lean Sigma projects, even in processes where there are no obvious targets.

The heart of Lean Sigma is Wedgwood's 48 individual "tools roadmaps": step-by-step instructions revealing exactly how and when to use all these Lean Sigma tools...
