Our whole lot mapping methods seem really primitive, a literal tag (published sheet of paper) that literally complies with the parts


We have won 14 brand-new agreements in the last 4 months, and new production is beginning within a year. We require to be able to narrow it down to the change at a minimum. Preferably the time, driver, maker, part #, batch #, amount.

There are generally production sampling plans to guarantee that everything remains in control along the means.
