Jeff gave the latest iteration of his talk, Scrum: The Future of Work, laying out where Scrum came from, the state of the art, and where he sees it going.
People asked for the slides and some of the patterns he discussed. They can be found on this page. You can also find some papers on Distributed Scrum, Scaling Scrum, and Scrum in Church. We hope to have the video up there soon as well.
