Roy Roberts and Susan Unger both face huge communications tasks.
Roberts is in charge of GM sales and marketing in North America, which was vastly reorganized this year. The company pushed decision-making into five regions and eliminated its dealer advertising groups.
He must communicate the company's new vision to both dealers and its own field staff. The job was compounded last month when GM stunned dealers by announcing plans to buy up to 10 percent of its U.S. dealerships.
Unger, DaimlerChrysler AG chief information officer, must ensure that the technology is in place for its employees to communicate around the world.
Roberts and Unger will speak during the Tuesday morning session of the 2000 Automotive News World Congress.
Roberts, 60, joined GM in 1977. He has held various manufacturing and marketing jobs, including general manager of Pontiac-GMC.
Unger, 48, is also a senior vice president of DaimlerChrysler Corp., the automaker's North American sales arm.
Unger and Kathleen Oswald, senior vice president of human resources at DaimlerChrysler Corp., are the highest-ranking women in the new company.
Before the merger of Chrysler Corp. and Daimler-Benz AG on Nov. 17, 1998, Unger set up an internal Intranet communications system and a public Internet site. She manages employees on both sides of the Atlantic.
