As I have earlier noted, the most important things in life and in business can’t be measured. The trite bromide 'If you can measure it, you can manage it' has been a hindrance in the building a great real-world organization, just as it has been a hindrance in evaluating the real-world economy. It is character, not numbers, that make the world go ‘round. How can we possibly measure the qualities of human existence that give our lives and careers meaning? How about grace, kindness, and integrity? What value do we put on passion, devotion, and trust? How much do cheerfulness, the lilt of a human voice, and a touch of pride add to our lives? Tell me, please, if you can, how to value friendship, cooperation, dedication, and spirit. Categorically, the firm that ignores the intangible qualities that the human beings who are our colleagues bring to their careers will never build a great workforce or a great organization.
