This calls to mind a discussion I had with a production engineer about possible savings in producing offshore. He said to me, “If you get on a plane the instant you discover a problem, you’ll have five weeks of production in the pipeline that isn’t fixed by your solution.” That’s a lot of re-work to pay for. What this means is that when planning, engineering and production are all in the same place, mistakes or adjustments are less costly. Doesn’t this apply to automobiles? Imported autos are subject to tariff, but given sufficient production numbers, assembling or producing them in the destination country, even though more expensive, can save money by avoiding this.
