“’Measurement is not an end in itself . . .’ might seem to be a paradoxical way of introducing a book about measurement. But measurement is important to the majority since it gives objective evidence on which to base decisions.”

“Presenting measurement in relation to objects will allow measurements to be anchored in relevance and interest for third parties. As it turns out, the approach also provides the key to a unified presentation about quality-assured measurement across Social and Physical Sciences where objects are probed by Man as a measurement instrument.”

“There is a growing awareness that many of society’s so-called ‘big challenges’— global climate change, the aging population, etc. …—should be tackled with increased mobilisation across disciplinary boundaries between the social and physical sciences to reach an increased stringency, for example, in decision-making 1and conformity assessment.”

“One of the most difficult tasks in performing a measurement is to separate measurement dispersion from actual product variation.”

“Measurement system analysis (MSA) is an essential tool in configuring the necessary measurement resources to have properties commensurate with the task ahead”

“Measurement is a ‘concatenation of observation and restitution’ (as recalled by Bentley 2004; Sommer and Siebert 2006; Rossi 2014).”

“Rasch measurement theory provides for restitution in the measurement process when Man acts as a measurement instrument”

“Accuracy (decision-making) = response categorisation — input (true) categorisation”

“A Rasch approach to perceived beauty or perceived happiness (or other pleasing patterns and degrees of order or symmetry) would in fact provide separate measures of the(albeit noisy) individual preferences of different persons and the intrinsic ability of, respectively, Leonardo’s painting to stimulate pleasure or a particular activity of daily living to invoke happiness. This objectivity is perhaps not as strong as evaluations about the physical world (which would exist of course even without a human presence (Denbigh and Denbigh 1985), but is so to say ‘fit for purpose’ in the human-based context relevant for the present study.”

“A useful point of departure for introducing units in measurement is to recognise the analogous role of words in making efficient communication with language.”

“Two distinct contexts where one seeks stationary (minimum or maximum) values of the entropy—that is, the amount of information— can be identified: (1) the best units for traceability are those with most order, i.e. least entropy, as an example of the principle of least action; (2) the change in entropy on transmission of measurement information cannot decrease, thus allowing realistic estimates of measurement uncertainty, in line with the second law of thermodynamics.”
