Actually, the concept of quality is an overlay of meanings: from the Old
French, qualité, (excellence or fineness); the Latin, qualitas (state, basic
nature, property, character or attribute); and the Latin, qualis, (of what
sort or kind).
A fundamental attribute of the quality concept is that it allows us to think
of qualitative relationships in three important ways, one of which
(qualitas) includes the property of number.
Quantity is a qualitative attribute, property or element of quality, and in
designing not necessarily the most important one.
