The grill: Cheryl Whitis

Cheryl Whitis is vice president and CIO for Raytheon's Network Centric Systems, a group with 13,000 employees, 8,000 of whom are engineers and scientists. Working in the aerospace and defense field is a passion for her, one she discovered almost by accident with her first job at Northrop Worldwide Aircraft Services. The industry holds a personal significance for her as well: Both her father and father-in-law are career Army servicemen, and Whitis takes pride in the fact that she contributes to U.S. national defense and the protection of its war fighters.
