Measures of Specification and Design
Chapter 3’s introduction to model-based measurement amounted to a warning: no number or symbol can characterize an entity meaningfully, unless there is a formal model which establishes the context. Recalling Lord Kelvin’s motto, the same message can be put more explicitly: “What is not measurable, make measurable through its formal model”. Once a formal model exists which represents selected attributes of a referent, the model displays these as measurable properties. In addition, the model will often reveal further properties which point to unidentified inherent attributes, enriching the picture of the referent and enhancing understanding.
