If you are told that something cannot be measured because there is no way to put an exact number on it, then you know that the problem is a misunderstanding of the measurement concept. The way scientists see it, measurement is the reduction of uncertainty about a quantity through observation. If you tell me more than I knew before, then you have reduced my uncertainty. If you have told me that orders would be filled 10 to 30 percent faster with some proposed system, then you have reduced my uncertainty if I previously thought the range was 0 to 60 percent. It s just a calculation.
Measurements are pragmatic observations and observation never eliminates uncertainty.
Simply put, a probability distribution is a range of possible outcomes and their possibilities. If you can reduce the range of possible values by a bit, you still have a measurement. In fact, that small change in uncertainty might be enough to sway the decision. Anything is measurable in a way that is superior to not measuring it at all. Teams A fter intangibles have been clarified by developing unambiguous definitions and measurement itself is better understood, many more things appear to be measurable.
