Collaboration technologies offer benefits for organizations to make teamwork more productive and creative. Yet the organizational transition towards using particular types of collaboration technologies is often fraught with challenges. A key condition for successfully transitioning towards a new way of working is that the stakeholders are committed to the outcomes of the new collaboration process. Little is known about the antecedents of this commitment. This study investigates the antecedents of user commitment using the Technology Transition Model (TTM) and Yield Shift Theory (YST). Specifically, this study examines the effect of satisfaction with process (SP), satisfaction with outcomes (SO), and perceived magnitude of net value (MNV) on user commitment (C) to the results of collaborative work practices. Subjects from three international organizations participated in the study. Results show that MNV and SO predict commitment while SP partially predicted commitment, with MNV the strongest predictor.
