We see this in plastic extrusion: ambient temperature and humidity play a measurable role in the product that comes off the line, and the process that gets it there. Shift in humidity = adjustment in drying of raw material & tweak to drying time as the product comes off the line = variability in total production time, for example. Surprisingly, as referenced in the Bombardier example, adjusting to ambient environment is often manual/overlooked: it’s trial and error on the manufacturer’s part to make the adjustments necessary.
