Measurement

George Bernard Shaw wrote once, " The only man who behaves sensibly is my tailor; he takes my measurements anew every time he sees me, while all the rest go on with their old measurements and expect me to fit them”

 

It is imperative that the measurement is industry specific, threat specific, vulnerability specific ,technology specific . 

There cannot be any universal or static measurement that can be expected to be valid at all time and for all verticals.

"The scientific method is at base  analytic scrutiny, exact measuring, careful recording, and judgment on the basis of observed fact. Science in education is not a body of information, but a method, and its object is to find out and to learn how."
Leonard P. Ayres (1918) History and present status of educational measurements. In G. M. Whipple (Ed.), 17th NSSE Yearbook. Bloomington IL: Public School Pub. Co. p

Approximations and measurement

Collateral damages, concomitant benefits, unintended consequences, serendipitous occurrences, ancillary qualities, logical obverse are applicable in all domains.

All widely and normally accepted approximations are ok as long as they serve the purpose adequately.

100% measured accuracy and/or perfection is by itself a doubtful thing.

Measurement is essential to experiment or evolve parameters or evaluate results.

However, in certain cases the very measuring tools or measurement yardsticks themselves have been proven to be arbitrary and not adequately acceptable due to some basic short comings in which has baffled later day scientific methods. 

Hyper consciousness to perfectionism may not allow one to do many things with confidence be it excessive attention to grammar or too technically correct presentation of music or cooking a perfectly tasty food.

Most routine activities we perform without looking for measuring.

We don't time the brushing, bathing, breathing intervals or cooking. Hardly anyone cooks with weighing machine near the stove by habit, repetition and practice the ingredients are mixed resulting in some edible food.

Imagine if one has to measure 3 grams salt, 10 grams chilli powder to make a sambar. What about the variable of intensity of saltiness of a particular brand of salt, spiciness of chilli etc.

How about measurements themselves?
