These serve as behavior-shaping constraints as the action of "car in Park (or Neutral or "foot depressing the clutch/brake pedal" must be performed before the car is allowed to start.2 Shingo argued that errors are inevitable in any manufacturing process, but that if appropriate poka-yokes are implemented, then mistakes can be caught quickly and prevented from resulting in defects.Journal of Quality Technology.But that is just one of their advantages.Citation needed A methodic approach to build up poka-yoke countermeasures has been proposed by the Applied Problem Solving (APS) methodology, 8 which consists of a three-step analysis of the risks to be managed: Identification of the need Identification of possible mistakes Management of mistakes before.
