Question

Quizplus · Accepted Answer

Poka-yoke is a Japanese term that refers to a mechanism that helps an equipment operator avoid (yokeru) mistakes (poka). Its purpose is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur. The electric sensor that prevents the closing of a garage door if something is in the way is a classic example of poka-yoke, as it automatically prevents a mistake (closing the door on an object or person) from happening.
