Some argue that the definition of many measurement methodologies are imprecise, and consequently it is often unclear how tools for computing them arrive at a particular result, while others argue that imperfect quantification is better than none (“You can’t control what you can't measure.”).
Neki tvrde da je definicija mnogih metodologija merenja neprecizna, stoga je često nejasno kako se određeni rezultat dobio, dok drugi smatraju da je nesavršena kvantifikacija bolja nego da je nema (“Ne možes kontrolisati ono što ne možeš izmeriti.”).
