What is Poka Yoke?
This is a Lean manufacturing process that helps to reduce mistakes in the production process. It is a system that is set up to prevent, correct and draw attention to the errors of the machinery as they occur. A good example, is thinking of a manual car. The drive has to put his foot on the clutch to allow for changing gears, reducing the error of being in a gear when you shouldn't - but doesn't work for being in the wrong gear but the lovely sound should notify you.
