When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the stage of science — Lord Kelvin
When we contrast that with Einstein quote
Not everything that counts can be measured. Not everything that can be measured counts.
We need to ask what is the context and domain of the measurement. If you're accoutable to the stockholders of investors, maybe you want to consider measurement as a starting point for your success.
