A recent Computerworld article, Wikis that work: Four IT departments get it right, provides early adopters success stories at Enel, ShoreBank, NYK, and SAP. The first two used Traction Team Page, NYK used Atlassian's Confluence and the SAP example did not mention a vendor. This is a comprehensive article that goes into good detail on each example. I recommend looking at the complete coverage.
Enel used wikis as a way to make IT materials more accessible to their end users. They now achieve self-service for IT information that was previously delivered through e-mail or over an intranet. They also use the platform as a central hub for network and license information instead of storing the data in separate Word documents. In this capacity, they take advantage of TeamPage's security features to ensure that information is only accessible to approved IT staff. Enel also continues to use the wiki as a project management tool (see – Making Wikis Work at Novell). I have covered the Shore Bank example before and project management is one of the main uses (see - Another Enterprise Blog and Wiki Success Story from Traction – Shore Bank).
NYK Group, the logistics and trucking arm of Japan-based container and shipping company NYK Logistics, is using an enterprise wiki within its IT department for a number of tasks: project management, change management and knowledge management. For example, instead of using broadcast e-mails on hardware changes or software upgrades, IT now notifies anyone affected by the changes via a wiki with subscription notification capabilities. Separately, NYK uses a wiki to keep multiple peer IT groups in the loop on the status of various projects.
SAP's Software Developer Network (SDN) wiki is a reference and collaboration tool for more than 1 million independent SAP software developers. It uses a point system to encourage participation and recognize its most active and valued members. As Beth writes, under the SAP Contributor Recognition program, members are awarded points for every technical article, code sample, blog post and wiki contribution they make. SDN employees rank wiki posts based on their content and value to the community. I have covered the
From these examples, it seems that once a wiki gets launched in an organization, many new uses spring up. I have heard of this many times before and it is nice to see the pattern repeated. Thanks to Jordan Frank of Traction who alerted me to this article.
