Comparison/Contrast Both offer
Searching Document sharing/managing Contact information
Discovery Server Discovers knowledge, relationships K-maps
SharePoint More customized view (portal: calendar, news, etc.)
![Page 22: KM Technology Assessment “Knowledge and team collaboration servers” DSC8030/CIS8260 Dr. Samaddar Summer 2004 Jon A. Preston](https://reader035.vdocuments.net/reader035/viewer/2022070409/56649e915503460f94b964ea/html5/thumbnails/22.jpg)
Deployment Considerations Consider existing IT infrastructure
Lotus Notes → Discovery Server Microsoft Office/Exchange → SharePoint
Integration to other systems possible, but potentially problematic Upgrades could break links
Leverage existing interfaces K-map rules/relations may require
“oversight”

Conclusions Online collaborative tools vital
Sharing documents Version control, profiling
Personnel directory/searching Provides views of company Access to experts
Tool selection dependant upon current technologies in place Document/user size may be a consideration
