Quantity

Definition:

A Quantity describes “How much” a System performs or consumes.
A Quantity is an Attribute measured in terms of Capacity (*459) or Resources (*199).
A “quantity” is a Type of Attribute which we would not normally call a “Product-Value” (*125)

Detailing

Rationale: conventional thinking assumes that qualitative ideas cannot be quantified. We are trying to emphasize that there are at least two kinds of measurable Attributes: Product-Values and quantities. Quantities being the conventional variables of performance and Resources which we conventionally expect to Quantify and to Measure. See [CROSBY97] Alfred W. Crosby, The Measure of Reality. Quantification and Western Society 1250-1600, for a historical perspective of how society gradually absorbs more quantification.
