#1: Image Gallery: 25 Most Influential People in Telecom Software
Thaddeus Arroyo, CIO, AT&T
Thaddeus Arroyo manages one of the largest IT organizations in the world. That alone makes him influential. He is responsible for AT&T’s corporate-wide information technology functions and he not only was instrumental in the company’s merger with Cingular Wireless, but lived to tell about it. He is influential because of his experience, his clout as a trendsetter and his position in the HITEC 100, the first list recognizing the top Hispanic IT leaders in the United States. Arroyo also is co-chair of the CIO Council at ATIS. The CIO Council provides a venue for CIO-level representatives to proactively identify and discuss IT challenges for the industry and to frame, coordinate and advance solutions to common IT issues. It lets them offer perspective and direction to the development of standards, guidelines and best practices in support of this mission. Arroyo is currently helping to support the ATIS Cloud Services Forum and address security in the cloud.
