One of the significant developments of knowledge management in a networked organisation is the application of information and communication technology (ICT) to support knowledge sharing among its members who are separated by distance. Even though much has been written on media selection for collaborative tasks in virtual teams, very little attention has been devoted to media selection and distributed online knowledge sharing environments. This paper reports part of a study that examines how ICT can support peer consulting, a knowledge sharing activity, among counsellors in a New Zealand not-for-profit human services organisation which has many small offices around the country. In particular, the paper describes Dennis and Valacich’s Theory of Media Synchronicity and how it can be applied to media selection to support various peer consulting activities.
