Our lot tracing approaches appear very primitive, a literal tag (published sheet of paper) that Going Here literally follows the parts


We have won 14 new contracts in the last 4 months, and new production is beginning within a year. We require to be able to tighten it down to the change at a minimum. Ideally the time, driver, equipment, component #, batch #, quantity.
