This document summarizes a case study of Ipsen implementing an enterprise weblog system for competitive intelligence. The system allows for the collection, analysis, and dissemination of intelligence on competitors and industry trends. After 15 months of use, the weblog system consolidated over 3,700 articles and 640 comments across 6 blogs. It is accessed by 250 users and available to 3,500 employees. The weblog has contributed to making competitive intelligence more valuable and facilitating market-relevant communication. Lessons learned include gaining executive support, having a clear objective, considering processes, gradual adoption, keeping training simple, and integrating the system. The weblog solution was found to work well for Ipsen's needs around collaboration and knowledge sharing.
