[satisfice]

"Quality is the absence of problems" is an example of the reification fallacy, because a problem is not a fixed thing. A problem is only a problem because someone decides it is so.

This is why a better definition is "quality is value to some person who matters." This definition instantly places you at the crux of the matter, which is not about a state of the world or of your product in the world, but rather about WHO matters and how they FEEL about your product.
