Our lot mapping techniques appear really primitive, an actual tag (published sheet of paper) that physically follows the parts


3. It should be able to support new development. We have actually won 14 brand-new contracts in the last 4 months, and brand-new production is beginning within a year. 4. Detail is everything.

Then there are usually manufacturing sampling plans to guarantee that whatever remains in control along the road.
