High valued assemblies tend to be manufactured in the USA. Defect detection early and often prevents waiting until completion to scrap them (much better to scrap when you only have $10,000 in subassemblies and labor into it than then when you have $50,000). If that assembly is a bottleneck you are also reducing the impact to your larger production schedule (scraping it one week into assembly versus 4). Computer vision is hugely important for this. Computer vision capturing each stage also greatly helps to quickly isolates what is introducing the situation resulting in scrap. Instead of having scrap meetings trying to determine why a completed assembly is failing you identify the failure point as close to when it occurs as possible. Being able to identify molds reaching end of life prior to parts failing QA for being out of tolerance is also huge for American manufacturing. Where it's way less important is when you are spitting out eraser tips or other 'high scale' manufacturing.
