It is now recognized that to broaden our understanding about networks more qualitative and longitudinal work is required that examines transformation and the change processes of networks; how they emerge and develop over time. The case study reported here deals with these issues. It considers the development of a network for new entrepreneurs first established by a local enterprise support agency in North East Scotland.This forum provided a near ‘natural experiment’ to chart network emergence, change and evolution. Employing participant observation, interviews and surveys, data were collected over a six-year period. This allowed the network to be mapped, and provided information about structural characteristics and in-depth detail about network dynamics and change processes over time. Findings show how network structure shifts from calculative to affective ties and demonstrate the importance of social ties for the operation of a network.
