A steadily increasing number of organizations are adopting mobile computing devices. There is broad consensus in literature that mobile information systems (IS) and information technology (IT) use can entail positive effects in an organizational context. However, scholars have begun to assess the downsides of mobile IS/IT, including work-life conflict, spillover effects, and increases in stress. The aim of our study is to provide a balanced overview of the benefits and drawbacks of mobile IS/IT use in the form of a conceptual research model in order to ultimately assess the net productivity impact of individual mobile IS/IT use in organizations. We base our model on a deductive-inductive research approach, combining an extensive literature review and 17 interviews with mobile computing experts in major German and Swiss public corporations. We provide a statistical validation of our measurement model using survey-based data, which enables other researchers to make use of our measurement instrument.
