“The problems that we face today, both big ones in society like the current health care debate and smaller ones like strategic business decisions, do not exist because we lack information, but because we don’t understand it.

In other words, the major obstacle to solving modern problems isn’t the lack of information, solved by acquiring it, but the lack of understanding, solved by analytics.”
