The head of Microsoft's business unit, Stephen Elop, has been appointed president and CEO of Nokia, the world's largest mobile handset maker.
Elop, has been overseeing Microsoft Office systems as the head of Microsoft's business division and will take up his position at Nokia from 21 September.
The Nokia Board said Elop has the right industry experience and leadership skills to accelerate the company's renewal.
"His strong software background and proven record in change management will be valuable assets as we press harder to complete the transformation of the company," said Jorma Ollila, chairman of the Nokia board of directors.
"We believe that Stephen will be able to drive both innovation and efficient execution of the company strategy in order to deliver increased value to our shareholders," Ollila added.
Nick Jones, analyst at Gartner, said Nokia's board has made a safe decision.
"Elop is an execution guy with a lot of large exec company experience. The challenge for Nokia is that none of Elop's direct experience is relevant to Nokia's problems. He's not a smartphone guy."
"Nokia has appointed him to make change. What to watch will be who he appoints to solve Nokia's problems," added Jones.
Current president and CEO of Nokia, Olli-Pekka Kallasvuo, will leave his position on 20 September, said Nokia.
