If things change, the inspection method must be different, right?

Today I had an investigator from a credit reporting company. There, he said.

I don't understand, but if the product changes, the inspection method will also change, won't it?
I don't think so. (Holding his business card) I remember that this is a good product. When we inspect, we check if there are any differences from good products. With this method, it is the same even if the product changes.
That's true.
But good products also vary, so by showing a large number of good products, the range of good products is automatically and statistically determined. If it falls within that range, it is a good product, that's all.

It is not only because it does not depend on the product, but also on a wide variety of industries....
