Microsoft has recently made a number of organizational changes aimed at making the company more nimble and efficient. The changes come amid growing threats from companies that provide Web-based software for tasks traditionally done by Microsoft's largely desktop-bound applications. The reorganizations have largely sought to help the company make decisions more quickly. In general, Microsoft has been bulking up its work force. It currently employs about 70,000 employees worldwide, up from more than 63,000 as of last September. It also recently announced a set of new employee benefits, such as enhanced child-care benefits and better cafeteria food, that many saw as an effort to boost employee morale and loyalty.
