3. Cisco Executive Exodus
More than 30 major executives have left Cisco in calendar 2011, many of them some of Cisco's best-known senior vice presidents and channel-facing team members.
It was probably bound to happen given the consistent turmoil in Cisco's ranks over the past few years, but every week in 2011, it seemed, brought a fresh exit, from former channels marketing boss Luanne Tierney jumping ship to Juniper in January to 19-year Cisco veteran SVP Manny Rivelo exiting for F5 Networks in late October. Cisco's Mount Rushmore -- the cheeky insider's name for the Executive Biographies page on its corporate web site -- sure looks different this year than it did last.
