Summary: Process improvements for goof-proofing assy and fabrication
Review: This books provides extensive examples of jigs, fixtures and procedures to prevent errors during assy and fab of parts and subassemblies. The simplicity of the solutions is quite amazing. This is not a theoretical, academic discussion. The best part of the book, comprising 240 pages, are real world examples. Each case is presented with a problem statement and sketches of the before and after conditions. Be aware that the vast majority of discussion is towards PROCESS changes, not DESIGN changes. This is where I have some disappointment, as I am involved in design features for quality improvements (DFX). Several of the examples show issues that SHOULD have been addressed in the design and never have reached the factory. In my opinion a clever fixture is second choice to a design that eliminates the need. To that end, a classic example of a design change is given on p171. Process fixes such as the majority of the ideas presented in this book are nonetheless valuable and should be considered as "thought generators" to inspire factory personnel at all levels to look for opportunities for simple, low cost and effective solutions to current problems. This book will not sit unused on a shelf!
