With the goal of creating unified service offerings that can compete more effectively against the cable industry, AT&T announced plans Wednesday to realign its operations under four units that, in part, would result in the combination of the company’s wireless and consumer fixed line businesses under common leadership. The four units—consumer, business, infrastructure and diversified businesses—would each focus on specific subscriber segments instead of on specific offerings that could be targeted to a range of customers. Ralph de la Vega, the current chief of AT&T Mobility, would also assume responsibility for AT&T’s consumer fixed line offerings as head of the new consumer unit. The new business unit, to be headed by Ronald Spears, would combine the operations of AT&T’s Global Business Services division with the company unit in charge of small business clients. John Stankey, the group president of AT&T’s telecom operations unit, has been tapped as chief executive of the infrastructure division. The only unit to remain unchanged under the new structure is diversified businesses, which handles AT&T’s international investments, directory operations and pay phone businesses. That unit will continue to operate under the stewardship of unit CEO Ray Wilkins. Observing that, “our customers want a ‘one AT&T’ experience,” an AT&T spokesman explained: “these changes help us do that for both consumers and businesses.”
