This research project investigated the relationships between IS staff and other organisational actors in four organisations. Using a network-based approach borrowed from Sociology, the key actors, groups and institutional mechanisms that organisations relied upon when deploying and using IT were investigated and represented in a series of diagrams. Specific techniques to visualise and represent how organisations operate and how information circulates within them were developed. This helped the researcher analyse the key components in the interaction between IS and the rest of the organisation and make suggestions for a better contribution of IS staff to the management of organisations.
