Diane Bryant

Last April, Bryant was ­promoted from SVP to ­executive vice president of Intel’s data center group. Once Intel’s CIO, she now leads the chipmaker’s most profitable business, selling the high-end processors that last year brought in an impressive $18 billion in sales. But overall demand for server chips recently slowed, and Intel’s stock price has taken a hit. Bryant’s biggest challenge is to continue to deliver double-digit revenue growth—no easy task.
