In a presentation at last week's MIX09 event in Las Vegas, Microsoft designer Stephan Hoefnagels traced the evolution of the company's new Windows 7 operating system.
"This was a pretty wacky brainstorm that we had early on," Hoefnagels told the crowd. But, he said, it wasn't just a bunch of designers going crazy. Even these early sketches represent collaboration across the technical and design ranks. "In this brainstorm, for instance, all the disciplines were involved... developers, program management, user research. Everybody was coming up with these crazy ideas."
