Or you make quality explicit and let the customer decide: do you want Ikea furniture, or do you buy your furniture from a top tier furniture brand? Do you buy kia, ford, Rolls Royce?

Quality is a range, from very bad quality with no validation to 100% full coverage, full testing, works in all situations. Usually customers are not willing to pay for 100% and as a business you do not have the time nor budget to build for a 100% quality.
