The aim of this article is to describe how experince-based knowledge can be made visible by giving some examples of how this has been done in Swedish social welfare services, in collaborations between social services agencies and research and development (R&D) units. These examples will be linked to theories and discussed in relation to different research utilisation models. By using one of these models, it is argued that R&D activities can broaden the concept of evidence-based practice and help brigde the gap between research and pracice.
