No it isn't, as in it literally isn't. Quantification is the process of judging something numerically, objectively and in measurement. Qualification is just the opposite, judging something by its nature, essence or kind.
Software quality, like all kinds of quality, is always a subjective and experiential feature. Just like, when someone says, this piece of furniture is a high quality, handmade chair, in all likelihood they haven't performed a numerical analysis of the properties of the chair, they're expressing a subjective, direct sentiment.
The handmade movement in software, was exactly about this, putting focus on the personal, lived judgement of experienced practitioners as opposed to trying to quantify software by some objective metric, that's why individual people feature so heavily in it.
