Even if you shout "quality" at the top of your lungs...

I often see top executives of manufacturing companies writing in newspapers and other media that "quality is the key point of focus. When I see this, I wonder, "How are they thinking about specific measures?

I believe that there are various measures for quality in design. However, as far as quality in manufacturing is concerned, I feel that the only mentality is to "inspect more thoroughly" since in most cases all inspections have already been conducted. I think that the people in charge of the front line are probably in trouble.

But there is a way if you change your mindset.
Instead of using automatic inspection machines to sort out defective products, we can sort out good products. We can mechanically sort out only the "apparently good" products.
For example, if only 90% of the products are "apparently good," only the remaining 10% need to be visually inspected. The remaining 10% of the work is to sort out the good products from the suspicious ones that are "different from the good products". In addition to reducing the number of inspection man-hours, the inspection work becomes easier and safer.
Inline use of this method also makes it possible to detect the slightest change that occurs on the production line and take immediate countermeasures.
However, this concept is only valid when "strict" inspections are conducted to select only the good products. It is not possible to detect only a small portion of a product or a serious defect.

Another point to note is that the inspection equipment must be usable at the field level. If it is too difficult to use, i.e., cannot be put into operation, it will have no effect.

I am an "inspection equipment vendor" and I am aware that I am in a serious position regarding quality. I am more afraid of defective products leaking out than anything else, and I can't afford to keep adding more and more products to be inspected one after another and more and more defect modes. I am no different from those in the "manufacturing field.
