What is Traceability?
Traceability
Finding out which material became which product and where it went by following the bundle number.
What it means
When materials come in and each time a product is made, a lot number is assigned to the bundle, and which material lot goes into which product lot is recorded. LOT tracking is all about following this record.
There are two directions. One goes back from the product to the material, and the other goes down from the material to the product.
At the pen factory
On the 10th day, Pureun Academy complained that ballpoint pens were not provided. I followed the box number L-1109-2 and found that refill L-1109 had been received without inspection.
Why it matters
When a problem occurs, you can find the material that caused it and the range of products that contain that material. If you don't have a number, you have to doubt everything.
