"There does appear to be a shift between the value of a generalist CEO to a specialist CEO," Schloetzer said. "This appointment would be consistent with that trend." And while Immelt or Whitman may have brought big operational chops to the job, they also would have carried even more scrutiny to a job where the media tracks every move.
"With Dara coming in, people don't have those expectations," said Jeff Sonnenfeld, senior associate dean of the Yale School of Management. "He can operate in a continuing stealth mode."
Khosrowshahi will have the chance to create more of his own narrative and likely, get more space to get started in the job, said Charley Polachi, managing partner of an eponymously named executive search firm.
"Let's face it, if it had been Jeff or Meg, it would have been a media circus," he said. "This guy is going to get some more leeway, and get more time to put together a plan. It's not like there's a large dossier of him. He's going to get a chance to create a public persona."
One of the dangers of bringing in a well-known outside leader to a company is he may think he has all the answers, and try to imprint what worked at another company into a very different turnaround. Justin Wasserman, a managing director at the consulting firm Kotter International, points to Ron Johnson, the Apple retail executive who tried to rehabilitate JC Penney by cutting sales programs and radically overhauling the discount retailer's stores.
"He literally just followed the Apple playbook, and he could not have been more wrong," Wasserman said, noting he was struck by a comment Khosrowshahi made about how culture change doesn't come from the top, but is "written bottoms up," hinting at an important level of modesty.
CEOs with a rock-star status or accustomed to running massive companies also risk being seen as unapproachable to employees, an issue that's particularly important for the cultural change Uber needs. "There's this big aura around them," Sonnenfeld said of CEOs with bold-face names. "That seems harder to penetrate. They seem less accessible."
Perhaps most encouraging, said leadership experts, given the dysfunctional nature of Uber's search process, is that Khosrowshahi's selection suggests the board's process may have been less haphazard than it looked from the outside.
"I wouldn't use the term dark horse or savior, but when so many people were focused on this search and nobody came up with this outcome," Schloetzer said, "it suggests to me they were very careful in the process."
