As transdisciplinary and transformative research approaches, real-world laboratories (RwLs) come with many pitfalls. Their design and implementation place high demands on everyone involved, which means that realistically, things rarely go smoothly. The following Design Report shares the lessons learned about establishing and adjusting communication and organisational structures in RwLs.

What should we take into account when setting up real-world laboratories (RwLs)? In our analysis of the experience of (co-)designing three RwLs within the Well-Being Transformation Wuppertal research project, we examine both the origin of the project proposal and its implementation, from management, communication and inter- and transdisciplinarity to actor dynamics and recruitment criteria for staff. We especially highlight the effects of the initial co-design phase (project proposal) on the RwL’s implementation, focusing on the challenges which arose and how these were addressed.We conducted 19 semi-structured interviews, analysed relevant project documentation and reflected on the research team’s own experiences. The transdisciplinary and transformative dimensions of the RwL approach are the areas where significant lessons were learned. RwLs are unique in their extraordinarily strong need to balance different roles and resources, even as many of their challenges and solutions resemble those which also arise in transdisciplinary research. The uniqueness of RwLs lies in their objective to co-produce not only socially robust knowledge but also tangible real-world change through experimentation.
