Ms. Lyons, a 28-year HP veteran, took the CMO job in June 2005, three months after Mark Hurd was installed as CEO. Mr. Hurd succeeded Carly Fiorina, who was ousted by the HP board in February 2005.
'In due course'
The move is effective immediately, and an HP spokeswoman said the position will be filled "in due course." For now, Shane Robison, exec VP-chief strategy and technology officer, will oversee marketing activities.
Ms. Lyons had taken over as CMO from Mike Winkler, who retired shortly after her appointment. During Mr. Winkler's tenure as CMO, Allison Johnson, who was HP's senior VP-marketing and is now VP-worldwide marketing at Apple, led many of the global branding initiatives under Ms. Fiorina.
Ms. Johnson is now rumored as a potential candidate for the vacant marketing post. Other candidates potentially in the running include Gary Elliott, HP's VP-brand marketing, who worked with both Ms. Fiorina and Ms. Lyons and joined HP in 2002 through its acquisition of Compaq; and Satjiv Chahil, senior VP-worldwide marketing, personal systems group.
Mr. Chahil, a former Apple marketing exec, and partner David Roman, VP-marketing communications, PSG, are credited with the resurgence of HP's personal computer business.
Ms. Lyons will now be responsible for "strategic change management" in the printing and imaging division, reporting to Vyomesh Joshi, exec VP of that group. Ms. Lyons will remain in the Boise, Idaho, office where she also resided throughout her tenure as CMO.
