The workshop aims to understand how a living lab network structures contribute to system innovation. Living labs as system innovation initiatives can substantially alter established network structures. Moreover, structures can undergo alterations through subtle interventions, with impact on the overall outcomes of living labs. To understand how such change occurs, we develop a multilevel network perspective to study collaborations toward system innovation. We take this perspective to help understand living lab dynamics, drawing on innovative examples and taking into consideration the multilayered structures that the collaboration comprises.
