In the playground that is software development, Microsoft is trying to recast its image from the one who makes up the rules to one who can work with others to create those rules and, just as importantly, abide by them. Talking about interoperability and cooperative development with competitors, however, is hardly something new for Microsoft. As far back as 2002, Microsoft CEO Steve Ballmer said the company would strive to form closer partnerships with its rivals and become reliable and consistent in implementing established industry standards. Even recently, Microsoft general manager Bill Hilf has said his company's work on helping shape industry standards and interoperability is "one of its most progressive areas."
