In this paper we present the design and deployment of an Enterprise Knowledge Portal in the Brazilian subsidiary of Xerox Corporation. The first unique feature of this project is the use of the Object Oriented Hypermedia Design Method (OOHDM) as a tool to design portal, which is seen as an instance of a Web based Knowledge Management application. The second unique feature is the use of a customized business game devised to trigger changes in corporate culture that lead to the adoption of the portal as a tool to support everyday activities. We describe the technical specification of the Portal as a Web application, and discuss the business game and its deployment, reporting on the experience gathered from the whole project.
