This project examines the nature and emergence of social interactions - and whether and how they can be shaped to facilitate organisational performance. By focusing on how formal and informal structures shape the formation of realised interactions, the project builds on, and extends, an emerging stream of literature within the area of Organizational Design. Using advanced wearable devices, we will obtain data related to realised interactions, including psychophysiological measurements, enabling insights at a micro-scale level, and with a temporal granularity, previously difficult to obtain. We will combine this data with traditional network analysis as well as simulation studies to verify and generalise the empirical findings. The empirical setting for the project is a large financial institution. Because social interactions are paramount for information exchange and organisational performance,
