Question

If an operator finds it impossible to insert a part into an assembly incorrectly because of a physical device installed on the equipment, what lean concept has been successfully applied?

Accepted Answer

The lean concept applied is Poka-Yoke, a Japanese term that translates to mistake-proofing. A Poka-Yoke is any mechanism in a process that helps an equipment operator avoid mistakes by making it physically or logically impossible to perform an action incorrectly. By integrating these physical constraints into the equipment, the process achieves built-in quality because it prevents defects from being created in the first place, rather than relying on human vigilance to catch them later. A simple analogy is a USB plug; because of its specific shape, it can only be inserted into a port in one correct orientation, ensuring a successful connection every time.
