Revenue, cost, and risk.

These are the three goods of business — the three and only three reasons for expending money, effort and attention.

Imagine you’re no longer responsible for keeping your company’s computers up and running. Instead, you’re an epidemiologist. Rather than a new and very aggressive malware threat you read about a new and highly contagious virus … the statistics indicate 30% of those exposed become infected and roughly 1.25% of those infected die.

The U.S. has a population of 300 million. You do the arithmetic: Straight-line extrapolation predicts 90 million infections and more than a million deaths.
