Description
The Zero Quality Control (ZQC) is the most effective mistake-proofing approach. The system prevents defects as well as monitors processing conditions at the source and corrects errors that would cause defects.
Based on the breakthrough approach developed by Dr. Shigeo Shingo, mistake-proofing devices called poka-yoke are used to check and give feedback about each product or operation in the process, not just a sample. Poka-yoke is a technique used to prevent mistakes from occurring in a process. It involves designing a process in such a way that it is impossible to make mistakes.
This Mistake-Proofing PPT training presentation introduces the basic methodology of ZQC in a logical format and covers all aspects of this important manufacturing improvement strategy. You will learn that the culture of zero defects can be developed by training and educating teams on the approaches to poka-yoke, and using contact and non-contact methods with visual controls and auditory systems to create effective, reliable and low-cost poka-yoke systems that catch mistakes and prevent defects from happening.

1. Mistake-Proofing PPT training presentation (PowerPoint format, 16:9 widescreen)
2. The Inspection Exercise (PowerPoint format, 4:3 standard screen)
