The CoCreation Toolbox is a toolbox of methods for project leaders of science/society projects and all those involved in society-based research projects or interested in this field. The tools are prepared in an application-oriented way and serve to strengthen collaboration in Science/Society cooperations without neglecting the individual needs of the participants. Together with the partners of münster.land.leben, the tools were individually developed and enriched with practical experience, so that the stumbling blocks that arise in various project phases of the cooperation, so-called transfer obstacles, can be identified, addressed and overcome at an early stage.
