The explicit management of project experience (lessons learned on project planning and execution) has become of strategic importance to many organizations. This paper describes how to set-up and run a case-based repository for sharing project experience using an industrial-strength case study. The case study shows that it is both effective and efficient for the information seeker to have an experience repository at his or her disposal. In addition, lessons learned regarding the organization and population of such an experience repository are reported. An outlook describes the potential of additionally planned exploitations of the project experiences.
