Abstract. The demo paper introduces SURF, a tool for supporting the subjectoriented redesign of workplaces in production companies. The collaborative tool, inspired by the wiki and the subject-oriented philosophy, allows workers to raise issues and suggest solutions to be exposed to managers for workplace re-design purposes. The advantage of the tool is twofold. On the one hand it empowers workers, making them aware and actively involved in the workplace re-design. On the other hand, the tool makes management aware of actual problems occurring at the shopfloor and of the suggestions proposed by workers, thus supporting them in the effective re-design.
