1. Systematic Defect Triggering

It will trigger stop production when the production has exceeded the maximum continuous amount on the same defect at the same location.
Check for units that are currently sent to rework continuously due to same defect at the same location.
The maximum amount for systematic defect triggering is 3, which means when there are 4 units in a row having the same defect occurred at the same location, stop production will be issued.

2. Random Defect Triggering

It will trigger stop production when the production has exceeded the maximum failure percentage including the rework unit.
It was determined by using the percentage of total quantity failed where the calculation is total quantity failed divided by maximum quantity per checking which is set to 100 and check whether the value is greater than the percentage set to trigger stop production.
The reject percentage is set to 3%. Hence, when the failure percentage is greater than 3%, system will issue stop production to the work order.
