Mistake-Proofing for Operators: The Zqc System

by Shingo

The Zero Quality Control System (ZQC) is a mistake-proofing approach that prevents defects by monitoring processing conditions at the source and correcting errors that cause defects. Since it is human nature to make mistakes, ZQC does not blame people for errors, but instead finds ways to keep errors from becoming defects. In this breakthrough approach, mistake-proofing devices called poka-yoke are used to check and give feedback about each product...

Mistake proofing

I have this book for a few months now, and I use it as a guidence at my workshop place, it really has some good tips

Simple and straight forward for beginners

Whether you start with JIT/Lean or Quick Response Manufacturing, you need to learn some simple tools helping you with the process improvement after any process analyze. Many books about operations management will teach you the interaction of workstations and the parameters influencing the performance of a workstation, line or even a factory. Furthermore good operations books will give you the insights how to analyze the performance of a system. What often misses (which is Ok), is to provide the knowledge, e.g. if lot size reduction will bring a huge improvement for cycle-time etc., how to do this? Most of the books of this series exactly deal with this questions and present some methods that work and will simplify your life reading more sophisticated literature about this issue later on. All the books of the productivity press series were a great help to me. The following books of this series provided a good start about: - SMED: how to reduce change-over time and to make small lot sizes happen - TPM: how to improve machine availability and breakdown variability - ZQC: overcoming the problem of other quality methods, that only measure what was done but w/o pre-active prevention for rework/ scrap (Six-Sigma, SPC etc. are more complicated and not pre-active..) The series includes as well 5s and Pull Production etc. Especially the 3 titles mentionned above are a good introduction to related fiels. As your experiences grows, you might read more specific books about the subject later on. The data collection, e.g. for machine availability and variation etc., is not the objective of this book, but the method itself, how to to do it. For beginners, 5 stars is fair enough.
