In this paper I advocate the use of online communities as enterprise information tools, and I give some practical tips to managers and knowledge professionals interested in setting one up for this purpose. The paper concentrates on strategy rather than on individual technologies. Key learning points of this paper are: 1. Online communities within the enterprise usually fail if they are created using a top-down, hierarchical approach. 2. Begin your online community with hand-picked members. 3. Make sure that you can demonstrate concrete results. 5 Pages
