This book provides tools that are less commonly used and some tools that the author, Nancy Tague, created. Inside you'll find tools for generating and organizing ideas, evaluating ideas, analyzing processes, determining root causes, planning, basic data handling, and statistics. In this third edition, six new tools were added (i.e., DFMEA and PMFEA) along with a section on Quality 4.0 and suggested quality tools that can help facilitate practitioners looking to implement Quality 4.0 concepts. The use of icons with each tool description tells the reader at a glance what kind of tool it is and where it is used within the improvement process.
