Kevin Kennedy, who yesterday resigned his position as CEO and president of telecom equipment maker JDSU (formerly JDS Uniphase), was named CEO and president of Avaya Inc. this morning. Kennedy will replace Avaya Interim CEO Charles Giancarlo, who will become chairman of the telephone equipment maker. Kennedy helped revive JDSU, though with telcos tightening their capital spending, the firm will still have some choppy waters to navigate. At privately held Avaya, Kennedy will trade the harsh scrutiny of Wall Street for the pressure of running a leveraged private equity-backed company during a downturn. He will take on the role in January 2009.
