Imagine you are driving a car. The windshield shows you what is ahead, the rear-view mirror shows where you have been, and the dashboard tells you your current speed and fuel level. Decision-making without analytics is like driving blindfolded — you might move, but you will almost certainly crash. This chapter is about taking the blindfold off. We will explore how different kinds of analytics help us understand the past, explain why things happened, predict the future, and even suggest what to do next.
