Nadella told reporters at a special media briefing in New York on Monday that he's rethinking what that means.I'm a big believer that every company has to have a sense of purpose and mission, Nadella said. Firms don't need to outlive their relevance ... so therefore that sense of purpose and mission needs to be something that you have to keep front and center. Of course, you have to reinterpret this for what is a changing world.'Rethinking' Microsoft's missionNadella, who is 52, said he asks himself whether anyone would miss Microsoft if it disappeared tomorrow, and whether any sensibility the company represents would be lost. With that mind, he said he's revisiting the company's mission statement for the new decade.Microsoft's core sensibility is thinking about people and institutions from a software perspective, Nadella said. Nadella said doesn't think of business as either enterprise or consumer, but as people and institutions.This blurring of the lines between consumer and enterprise is already taking shape at Microsoft.Microsoft as recently as last month was hiring for a new team that a company executive once explained was part of a vision to win back the magic it lost with consumers. The idea is to create a business that serves the personal and professional aspects of customers' lives.Microsoft's mission statements over the yearsMicrosoft's mission under founder Bill Gates was to put a computer on every desk and in every home. Nadella on Monday said that was a bold goal, but not a mission as Microsoft had pretty much achieved Gates' vision in the developed world by the end of the 1990s. (Nadella has spoken about this in the past, saying it always bothered me that we confused an enduring mission with a temporal goal.)The company's previous mission statement, under former CEO Steve Ballmer in 2013, was to create a family of devices and services for individuals and businesses that empower people around the globe at home, at work and on the go, for the activities they value most.While it took a while before Nadella changed Microsoft's official mission statement, he started undoing Ballmer's pretty quickly. He told employees in an internal email shortly after starting the job that devices and services was helpful in starting Microsoft's transformation, but it needed a new strategy.Nicholas Carlson contributed reporting to this story.Got a tip?
