“Measuring requires, first and foremost, analytical ability. But it also demands that measurement be used to make self-control possible rather than abused to control people from the outside and above—that is, to dominate them. It is the common violation of this principle that largely explains why measurement is the weakest area in the work of the manager today. As long as measurements are abused as a tool of control (for instance, as when measurements are used, as a weapon of an internal secret police that supplies audits and critical appraisals of a manager’s performance to the boss without even sending a carbon copy to the manager himself) measuring will remain the weakest area in the manager’s performance.2”

“The lesson here is very simple. But it is striking how often it is overlooked. We are so caught in the myths of the best and the brightest and the self-made that we think outliers spring naturally from the earth. We look at the young Bill Gates and marvel that our world allowed that thirteen-year-old to become a fabulously successful entrepreneur. But that's the wrong lesson. Our world only allowed one thirteen-year-old unlimited access to a time sharing terminal in 1968. If a million teenagers had been given the same opportunity, how many more Microsofts would we have today?”

“But the order in which these sources will be discussed is not arbitrary. They are listed in descending order of reliability and predictability. For, contrary to almost universal belief, new knowledge – and especially new scientific knowledge – is not the most reliable or most predictable source of successful innovations. For all the visibility, glamour, and importance of science-based innovation, it is actually the least reliable and least predictable one. Conversely, the mundane and unglamorous analysis of such symptoms of underlying changes as the unexpected success or the unexpected failure carry fairly low risk and uncertainty. And the innovations arising therefrom have, typically, the shortest lead time between the start of a venture and its measurable results, whether success or failure.”

“The tipping point is that magic moment when an idea, trend, or social behavior crosses a threshold, tips, and spreads like wildfire.”
