We start with results. Each December, when we choose Fortune’s Businessperson of the Year, we run the numbers, weighing 10 financial metrics including 12-month and 36-month increases in profits and revenue (we use a three-year window to eliminate any companies that post a great year following a slump). We also weight stock performance and total shareholder returns over the same period. Only then do we factor in those intangibles that separate so-so CEOs from the standouts—things like business influence, strategic vision, and the impact of their leadership. The result? Twenty businesspeople who delivered.
