KM Technology Assessment “Knowledge and team collaboration servers” DSC8030/CIS8260 Dr. Samaddar Summer 2004 Jon A. Preston

Agenda  Motivation/Need  Importance of collaboration servers  Leading Products IBM/Lotus Discovery Server Microsoft SharePoint Portal Server 2003  Comparison & Contrast  Deployment Considerations  Conclusions

Motivation/Need  Formalize knowledge markets  Discover patterns of knowledge  Identify covert experts  Capture knowledge formally Best practices Technical reports Status of documents/projects

Collaborative Servers  Bring people together KRD type information  Act as electronic librarians Search for expertise, papers, etc.  Manage projects  Provide “total view” of company Avoid blindness Selective blindness

Industries Business practices and processes that focus on information access, knowledge sharing, business application availability, and collaboration between remote users are the best candidates to be implemented within a portal framework across business domains that include financial services, manufacturing, and telecommunications companies. - Cognizant Technology Solutions (2002)

Enterprise Portal Market

Leading Products  IBM/Lotus Discovery Server 1550 worldwide installations (2002)  Microsoft SharePoint Portal Server 2003

IBM/Lotus Discovery Server  Search  Expertise Location  Capture “relevant experiences”  Extracts, analyzes, & categorizes  “Reveals” relationships  Automatically generates and maintains K-maps  Generates & maintains user profiles – “uncovers” knowledge

Searching

Knowledge Broker  Provides affinities  Provides contact information  Denotes availability Off-line On-line Do not disturb

Performance Improvements in Concurrent users Documents in system Total searches per hour Average response time (sec) CPU usage (percent) HTTP CPU usage (percent) ,0005,

Microsoft SharePoint Portal Server  “Connects users, teams, and knowledge”  Enterprise solution  Single log-on (point of access)  Customization & personalization of portal Organizational role Team membership Interest Security  Locate documents, processes, and best practices  Integrates into existing applications

Searching  Files  Web servers  Microsoft Exchange Server folders  Lotus Notes  Automatic/push notification on additions and changes

Document Management  Versioning  Approval workflow  Check-in and check-out  Status tracking/profiling

Customized Information

Searching

Document/Information Sharing

SharePoint Performance Number of usersRecommended topology < 1,000 Single server with Microsoft SQL Server 2000 Desktop Engine (MSDE) < 10,000Single server with SQL Server 2000 < 25,000 * Small farm: Front-end Web server (1), SQL (1+, optionally clustered) < 100,000 Medium farm: Front-end Web server or search (2), index or job (1), SQL (1+, optionally clustered) > 100,000 Large farm: Front-end Web server (2+), search (2+), index (1+), SQL (1+, optionally clustered)

Single Server Server type RAMHard diskCPU Web, index, search, and database 1 gigabyte (GB)100 GBDual 2.8 GHz Pentium 4 A system built with the hardware described in the preceding table should have the following performance characteristics: Process 15 requests per second (Peak common action) (including 2 searches per second) with MSDE Note MSDE has a database size limit of 2 GB and a limit of 5 concurrent jobs. Process 32 requests per second (including 4 searches per second) with SQL Server Index 5 documents per second Store up to 100,000 documents (using SQL Server) Index up to 1 million documents (using SQL Server) Host up to 10,000 team and personal sites Host up to 5 portal sites (using shared services)

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.)

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
