Summary.
We live in an era of risk and instability. Globalization, new technologies, and greater transparency have combined to upend the business environment and give many CEOs a deep sense of unease. Just look at the numbers. Since 1980 the volatility of business operating margins, largely static since the 1950s, has more than doubled, as has the size of the gap between winners (companies with high operating margins) and losers (those with low ones).
