I also used to work in manufacturing and whenever we started making a new product, the first batch of units is hand-checked by operations, then hand-checked by engineering, then a handful are kept as gold standards references. If there are any problems, it’s all hands on deck working overtime to get them fixed immediately, because YOU DON’T KEEP MAKING FAULTY SHIT.
