Shared Spaces Research & Consulting: Response to the Sirana Roadmap for Exchange, Jan 13: "Microsoft lacks a roadmap for its Exchange Server product (although one is due next week apparently), which I discussed last month. Chris Williams of Sirana Software, who previously worked on the Exchange product team for six years and was a senior product planner for Exchange Server 2000, has published a two-part manifesto for Exchange Server (short-term and long-term). I applaud Chris for publishing his thoughts, and in this post I want to consider the points he raises in light of my ruminations on this topic."
More thoughtful analysis/insights from Michael Sampson; see his post for links including Chris Williams' Exchange manifesto.
From my perspective, the key longer-term issue is the underlying application metamodel -- Exchange is now a robust platform for async enterprise communication (email, calendaring/scheduling and personal information mgmt for contacts and to-dos etc.); Notes/Domino is all that along with a much broader/deeper/better integrated application metamodel for document-centric, workspace-based collaboration. I look forward to someday seeing a similarly expansive application metamodel from Microsoft -- as well as from IBM (for Workplace rather than Notes/Domino) and Oracle.
