We are looking to Trace product back to each packing line. We have 16 packing lines and more specifically we are looking to trace back to the employee packing the product. We are going to use this tracability exercise to assist us in seeing how well each employee is doing at their job; employee reviews. Each packing line contains a label put on product, however I do not want to write the individuals name on the label. I believe I want to assign each employee a number and write the number on the label.
Does anyone have experience in doing such a thing. I would like to know some pro's and con's, what I should and should not do, etc. for doing this so I set the program up to succeed.
