HP decided against conducting an outside search because it wasn't necessary, board Executive Chairman Ray Lane said . But having just conducted the search for Apotheker, HP still had a good idea of who was available and "if we thought there was a better choice on the outside, we would have conducted [a new] search," Lane said.
But if Whitman doesn't last, here's a look at some potential outside CEO candidates HP could pursue down the road:
Mills' name came up regularly as a potential HP CEO after Hurd left the company. In addition, he would bring broad-based experience to HP thanks to his current role, where he oversees IBM's software and hardware strategy and manages more than 100,000 employees.
Mills was also at IBM in the 1990s, when the company went through a similar transition as HP is going through now, said Frank Scavo, managing partner of IT strategy consulting firm Strativa.
