INTRODUCTION. The use of actor-network theory is becoming increasingly common amongst information systems researchers. This study argues that the utility of actor-network theory as a conceptual tool for information systems research can be increased by expressing actor-network theory in a graphical format. To this end, a graphical syntax was designed based on a comprehensive conceptualisation of actor-network theory.
METHOD. Design science research was used to produce an artefact (the graphical syntax) which is believed to be of practical use (relevant), innovative and based on a rigorous body of knowledge.
ANALYSIS. The graphical syntax is illustrated in this paper only by means of a fictitious example in order to maintain focus on the syntax and the concepts depicted by the syntax.
RESULTS. The strengths and weaknesses of the syntax are related to those of actor-network theory itself. The principal strength is the inclusion of heterogeneous actors in the analysis, and the main weakness relates to the vague boundaries of the theory. This weakness is addressed by the ability of the syntax to identify the primary research foci.
CONCLUSIONS. It is proposed that actor-network theory can be successfully represented by a graphical syntax and that it can increase the utility of actor-network theory as a conceptual tool for information systems research.
