Prediction V/s Detection -POKA YOKE

A. Prediction V/s Detection :
When a Poka-Yoke is designed in a way that it helps the operator to recognise the defect before it is about to occur, it is called a Prevention or Prediction type Poka-Yoke.

When a Poka-Yoke helps the operator to know immediately on the occurrence of the defect then it is called Detection type Poka-Yoke.

Detection is “after” the defect is produced. The merit of this type of Poka-Yoke is based on the stage at which the defect is detected.
