There is a common saying that “if you can’t measure it you can’t manage it.” Many people mistakenly think the reverse is true, that if they can measure it, or something they call “it,” they can manage it. What they ignore is an old lesson from some of the greatest scientists—just because you can obtain numbers from measuring some key performance indicator does not mean the thing you think you are measuring actually exists. What then are you managing? Businesses measure and create all sorts of performance indicators without asking whether they indicate what they think they indicate. Often they do not.
