Four senior Microsoft executives, including Stephen Elop and Mark Penn, will leave the technology company in the biggest organisational shake-up yet under Satya Nadella, its chief executive.
In an email sent to Microsoft employees on Wednesday morning, Nadella said that three of the departures were related to his decision to organise the company's engineering efforts into fewer groups. The three executives leaving as a result are Elop, former chief executive of Nokia, who has been leading Microsoft's devices group; Eric Rudder, leader of its advanced technology and education efforts; and Kirill Tatarinov, head of its business solutions group.
