  • Quantify-me: consumer acceptance of wearable self-tracking devices

    Pfeiffer, Jurij; von Entreß-Fürsteneck, Matthias; Urbach, Nils; Buchwald, Arne (2016)
    The usage of wearable self-tracking technology has recently emerged as a new big trend in lifestyle and personal optimization in terms of health, fitness and well-being. Currently, only little is known about why people plan or start using such devices. Thus, in our research project, we aim at answering the question of what drives the usage intention of wearable self-tracking technology. Therefore, based on established technology acceptance theories, we deductively develop an acceptance model for wearable self-tracking technologies which sheds light on the pre-adoption criteria of such devices. We validate our proposed model by means of structural equation modeling using empirical data collected in a survey among 206 potential users. Our study identifies perceived usefulness, perceived enjoyment, social influ-ence, trust, personal innovativeness, and perceived support of well-being as the strongest drivers for the intention to use wearable self-tracking technologies. By accounting for the influence of the demographic factors age and gender, we provide a further refined picture.
  • Understanding employee engagement in un-official projects–A conceptual model based on psychological empowerment and constructive deviance

    Buchwald, Arne; Urbach, Nils; Mähring, Magnus (2015)
    Un-official projects resulting from unsanctioned, bottom-up employee initiatives is a phenomenon that can cause serious resource planning problems in IT project portfolio management, such as when resources thought to be available have actually been spent on projects conducted under the radar. At the same time, such project may also give rise to innovative ideas, solutions and software of potentially great benefit to organizations. Previous research has begun to acknowledge and highlight the innovative potential in bottom-up un-official activities, but little is known about why individual professionals engage in un-official projects. We draw on psychological empowerment and constructive deviance theory to explain such engagement, identifying factors fostering empowerment as well as factors moderating whether empowerment translates into unofficial project activities. Our conceptual model contributes to the theoretical discourse on un-official projects and equips practitioners with knowledge that can help them balance the propensity of individuals to engage in un-official activities.
  • Towards explaining the use of self-tracking devices: conceptual development of a continuance and discontinuance model

    Buchwald, Arne; Letner, Albert; Urbach, Nils; von Entreß-Fürsteneck, Matthias (2015)
    Users of digital self-tracking devices benefit from information about themselves. Thereby, the explanatory power of this information heavily depends on post-adoption continued usage of these devices. Thus, the aim of our research is to empirically analyze the factors that lead to continuous use of self-tracking devices. So far, research has largely focused on phases until IS adoption in a work environment and little on postadoption use in a consumer context which centers on either continuance or discontinuance. To advance research in this area, we develop a conceptual model that combines both in one comprehensive model by building on established post-adoption theories. We will continue our research with a quantitative-empirical evaluation of the developed model. With our research, we aim at contributing to both a better theoretical understanding in the field of IS post-adoption in a consumer context and giving practical implications for producers of self-tracking devices.
  • Understanding the organizational antecedents of bottom-up un-enacted projects - Towards a conceptual model based on deviance theory

    Buchwald, Arne; Urbach, Nils; Ahlemann, Frederik (2014)
    Un-enacted projects are those projects that have not been officially evaluated by the project portfolio management but do exist although they are not known to a company's project portfolio. As a consequence, resources thought to be available often prove to be actually unavailable and that unofficial initiatives eventually compete for scarce resources. One particular type of these un-enacted projects are bottom-up initiatives. Bottom-up un-enacted projects are unofficial initiatives on which employees spend time without order but with which they intend to benefit their organizations. While previous research highlights the great potential of bottom-up un-enacted projects, they only focus on the individual level but leave the organizational level for further research. To address this research gap, this study aims at gaining a deeper understanding of the organizational drivers of bottom-up un-enacted projects. We draw on deviance theory to develop a conceptual model for explaining the occurrence of these projects. In order to triangulate the emerging model with insights from practice, we use interview data to cross-check and refine the theory-driven model. Our results advance the theoretical discourse on the concept of un-enacted projects and enable practitioners to understand the levers with which to steer respective activities in the intended direction.
  • Understanding IT governance success and its impact: Results from an interview study.

    Urbach, Nils; Buchwald, Arne; Ahlemann, Frederik (2013)
    Owing to the increasing regulatory pressure and the need for aligned IT decisions, governance of IT has become important for both academia and practice. However, knowledge that integrates the determinants and consequences of IT governance success remains scarce. Although some studies investigate single aspects of IT governance success and its impact, none of these combine these factors into a comprehensive and integrated model. To address this gap, our research aims at understanding what factors influence and result from successful IT governance, and at determining how they can be translated into a model to explain IT governance success and its impact. Therefore, we conducted 28 interviews in 19 companies across different industries. Based on the analysis, we present a model that helps understanding what factors make IT governance successful and how IT governance contributes to an IT …
