Mistake-Proofing: Six Sigma PokaYoke: Via Fresh Inc.: Getting the Laundry Out ...

... "In the last century we even decided that quality should be treated as a science and created the profession of quality management. Since then we've developed tools like quality circles, total quality management, statistical process control, and Six Sigma, all designed to help us reach the nirvana of zero defects. " ...

A Brief Tutorial: "An example cited by Shingo early in the development of poka-yoke shows how finding mistakes at a glance helps to avoid defects. Suppose a worker must assemble a device that has two push-buttons. A spring must be put under each button. Sometimes a worker will forget to put the spring under the button and a defect occurs. A simple poka-yoke device to eliminate this problem was developed. "

Via Automation World Article: Pokayoke Sensing For Color (Features): "Pokayoke is a lean manufacturing technique by which mistake-proofing devices are used to keep errors from turning into defects. Tom Rosenberg, industry manager at sensor manufacturer Balluff Inc., in Florence, Ky., defines the term further as a system that is always checking. It's making sure the part is manufactured correctly before proceeding to the next stage of manufacture. "

The 7 Wastes of Lean: "These kind of issue can be tackled using mistake proofing methods (Pokayoke) and by understanding the machine process capabilities of the production equipment. Statistical process control (SPC) will also help monitor production outputs and give warning of problems before they occur."
