Microsoft is working on a tool called KN (Knowledge Network) that goes along with its KM-Collaboration product - MS SharepointPortal Server 2007 (SPS 2007). KN is on the lines of an SNA+Expertise Location tool that works in tandem with Active Directoty (Employee Profiles database), MS Outlook (Email) and MySite (Personal sites on MS SharepointPortal Server).
The MS KN team has a place in the blogosphere like many other MS individuals and teams. The team blog is here...
Given that SPS 2007 has a plethora of facilities as compared to its previous version, this in combination with plug-ins/add-ons like KN, Groove (A cool project workspace product taken over by MS a couple of years ago) etc definitely seems like a deadly KM-Collaboration product. (But I am left wondering how good the SPS default search engine will be. Hopefully better than that in the SPS 2003 version)
Anyways, looks like all the MS software-based organizations have lots to expect this year....!
