Literature on urban experiments and the role of experimental governance is increasingly focusing on the relationship between experimental processes and existing urban governance and planning configurations. This article aims to develop knowledge about institutional capacity and conditions for embedding experiments in mundane, everyday planning contexts. Based on qualitative interviews and document studies, we draw upon a research-led experiment which introduces digitally supported mobility interventions in a suburban neighborhood south of Stockholm, Sweden. We ask two questions: 1) which case-specific institutional capacities influence the embedding of urban experimentation? And based on this, 2) which general implications follow from the challenges of embedding experimental activities in mundane urban development contexts? Our results illustrate that mundane settings are challenging sites for embedding urban experimentation within broader strategic urban planning and development. In the case studied, limited strategic planning resources and the absence of an up-to-date strategic framing for the neighborhood’s development makes it challenging to integrate, and learn from, the experiment within its broader planning context. Broader implications from this case suggest that limited institutional capacity to embed experimentation in mundane planning settings implies an extended role for researchers to support conditions for embedding. We also identify a need for both researchers and public planning agencies to continuously safeguard democratic legitimacy and prioritization of scarce strategic planning resources. Embedding can be a demanding learning strategy. Involved actors ought to closely assess available capacity for embedding and identify activities which might support embedding in order to establish favorable conditions.
