Microsoft announced a sweeping reorganization of the company Thursday to "enable us to innovate with greater speed, efficiency and capability in a fast changing world."
The US technology giant said the "far-reaching realignment" would help integrate efforts around its software and devices.
"We are rallying behind a single strategy as one company -- not a collection of divisional strategies," chief executive Steve Ballmer said in a memo to employees.
"Although we will deliver multiple devices and services to execute and monetize the strategy, the single core strategy will drive us to set shared goals for everything we do. We will see our product line holistically, not as a set of islands."
Ballmer said the "One Microsoft" strategy would seek to bring together diverse segments such as Windows, Windows Phone, Xbox, Surface, Office 365 and others.
"Today's announcement will enable us to execute even better on our strategy to deliver a family of devices and services that best empower people for the activities they value most and the enterprise extensions and services that are most valuable to business," he said.
