It has been touted as “the single most important predictor of the value an organization generates from IT” (Weill and Ross, 2004, pp.3–4). In this paper, we present the results of a survey-based study of US and Canadian firms that utilise IT for electronic Human Resource Management (e-HRM) purposes. To investigate whether the mode of HR-IT governance matters in terms of the intensity of usage of HR technologies, we used the Diffusion of Innovations (DOI) theory in a moderated mediation functional form (James and Brett, 1984). We find that the way an organisation assigns responsibility for decision making for HR Information and Communication Technologies (ICTs) makes a difference in terms of the user (HR) and technical (Information Systems or IS) department factors that are statistically related to the intensity of HR technology usage.
