Analysts say Cisco customers might gain more input and clarity into the company's directions, but beyond that the reorganization means business as usual."You still have the same people running the show," says Dave Passmore, research director at Burton Group. "It's also interesting that they decided to reconstitute the CTO position after four years of vacancy. They [might have] thought it was necessary to better coordinate all of the development activities at Cisco."Giancarlo had been co-leader of network switching, one of Cisco's core technologies, as well as several advanced technologies, including voice, storage networking and network security. He also is president of Cisco-Linksys, Cisco's home network subsidiary.As CTO, Giancarlo will be responsible for contributing to and communicating Cisco's technology strategy, and managing Cisco's Global Government Solutions Group. He will continue to be president of Cisco-Linksys and lead the company's voice endeavors.Veteran executive Charlie Giancarlo (left) last week became the third CTO in Cisco\u2019s history.
