Verification of Knowledge Assets in Electronic Repositories: Expert- and Community-Governance

Two mechanisms that verify knowledge contributions in electronic repositories are expert-governance and community-governance. Our goal is to examine repository users' perceptions of the conditions under which these mechanisms verify knowledge contributions. Qualitative data show that perceived credibility of experts, perceived ownership of content, and experts' (meticulous) execution of governance functions are salient for expert-governance, and the perceived involvement of community members, and community members' (continuous and collective) execution of governance functions are important for community-governance.     

Extending technology usage to work settings: The role of perceived work compatibility in ERP implementation

Spanning over three decades and hundreds of studies, researchers have generated models, that examined user perceptions of technological attributes presumed to influence intention to use IT and consequent usage behavior. While these theories have provided reasonable explanations of IT usage across a broad range of technological and task settings, they did not address the role of IT in organizations, though they have been tested in organizational contexts, the models have not been modified to fit the context of organizational work. Current models are good at explaining IT usage in personal-settings, but they have not adequately examined the role of IT in organizations and thus have limited explanatory power in such settings. Furthermore, organizations deploy IT both to maximize its usage and to derive performance benefits from it. However, current IT usage models generally only consider IT usage as the dependent variable, without examining its performance impact. We extended IT usage models to include the role of IT's perceived work compatibility in shaping users’ IT usage intention, usage, and performance in work settings. The model was empirically validated using a field survey of 138 users of ERP systems in 62 firms in China.     

Extending technology usage models to interactive hedonic technologies: a theoretical model and empirical test

Abstract. Much of our prior knowledge of information systems (IS) usage is based on utilitarian systems such as personal productivity software and organizational applications. However, new generations of systems, such as online video games (OVGs), have since emerged that aim at enhancing users' hedonic outcomes like entertainment rather than utilitarian outcomes such as productivity. Prior models of utilitarian system usage provide a limited understanding of one's usage of hedonic systems, given the motivational differences between using these two types of systems. Theoretical modifications instead are required to extend the current models to hedonic systems. Expanding the research on attitude theories, we propose an initial model for usage of interactive hedonic systems, replacing perceived usefulness and perceived ease of use with perceived enjoyment and social image as the core cognitive drivers of usage, and further linking these beliefs to different technological attributes. The initial model is empirically validated using a survey of OVG usage among 485 student subjects. For IS usage research, this paper proposes and validates one of the earliest usage models of hedonic systems. For practitioners, this study provides some guidelines for manufacturers of hedonic systems on how to derive the most return on their system development efforts.     

User switching of information technology: A theoretical synthesis and empirical test

As competing technological choices emerge in the marketplace, an inevitable consequence is user switching from one IT product or service to another. However, we know very little of this phenomenon or the key drivers of user switching. We examined the reasons for IT switching by proposing a model that synthesized and extended current theories of IT acceptance and customer satisfaction. We believed that IT switching was driven by user dissatisfaction with an incumbent product or service and the fact that the customer was aware of the availability of a potentially superior product or service. Further, to explain differential switching patterns across an adopter population, we posited personal innovativeness as an individual difference variable that moderated the effect of user dissatisfaction and relative advantage of a new IT on users’ switching intention. Our model was empirically validated using a longitudinal survey of web browser switching among student subjects. We hope that our study will generate researchers’ interest in an understudied area of research and that the model will serve as a starting point for furthering our understanding of IT switching.     

Knowledge transfer and utilization in IT outsourcing partnerships: A preliminary model of antecedents and outcomes

We developed a nomological network of antecedents and outcomes of knowledge transfer and utilization in IT outsourcing relationships, and tested it using a survey of 146 IT outsourcing partnerships in Singapore.     

Gatekeepers’ innovative use of IT: An absorptive capacity model at the unit level

This paper examines the potential role of gatekeepers’ innovative use of information technology (IT) in organizational units and its ability antecedents. Using absorptive capacity theory as our theoretical lens, we theorize a model of innovative use of IT at the unit level. The proposed model was empirically validated using a survey of 204 unit gatekeepers. This paper develops a preliminary model of innovative use of IT that can inform and guide future research, specifically focusing on the key role of gatekeepers and the abilities needed by users in this role that can help in using IT in an innovative manner.     

A unified model of IT continuance: three complementary perspectives and crossover effects

This study presents a unified model of information technology (IT) continuance, by drawing upon three alternative influences that are presumed to shape continuance behavior: reasoned action, experiential response, and habitual response. Using a longitudinal survey of workplace IT continuance among insurance agents at a large insurance company in Taiwan, we demonstrate that the above influences are interdependent, complementary, and have crossover effects. This study advances IT continuance research by theorizing and validating a unifying model that extends prior perspectives and by explaining interrelationships between these perspectives.     

IS auditor characteristics,audit process variables,and IS audit satisfaction: An empirical study in South Korea

As a result of our inattention to the audit process, its antecedents, and its outcomes, the academic literature has lagged behind contemporary auditing practices as the demand for information systems audits has grown. To address this gap, we propose a model of IS audit satisfaction that includes auditor expertise (AE) and auditor role clarity (ARC) as antecedent variables that affect audit responsiveness (ARES) and audit reliability (AREL), which in turn affect audit satisfaction. We tested this model using survey data from 203 IS projects in South Korean public sector firms. Our results validate the significance of auditor characteristics (AE and ARC) and audit process variables (ARES and AREL) in shaping audit satisfaction. Implications for research and practice are discussed.     

Why end-users move to the cloud: a migration-theoretic analysis

This study presents and empirically validates a model of end-user migration from client-hosted computing to cloud computing. Synthesizing key findings from IT adoption and post-adoption research, switching research, and cloud computing studies, it builds an integrative framework of cloud migration using migration theory as a theoretical lens, and postulates interdependencies among these predictors. A longitudinal survey of Google Apps adoption among student subjects in South Korea validates our proposed model. This study contributes to our nascent body of knowledge on IT migration by drawing attention to this emerging phenomenon, demonstrating how migration research is different from IT adoption research, identifying salient factors that enable or hinder cloud migration, elaborating interdependencies between these different predictors, and bringing in migration theory as a referent theory to the information systems literature.     

Physicians' resistance toward healthcare information technology: a theoretical model and empirical test

This paper presents a theoretical model of physician resistance of healthcare information technology (HIT) usage by integrating the technology acceptance and resistance to change literatures, using a dual-factor model of technology usage. This model elaborates the interdependent and asymmetric effects of inhibiting usage perceptions, such as resistance, on HIT usage intentions relative to enabling perceptions, such as perceived usefulness and perceived ease of use. It also proposes perceived threat as a predictor of resistance, perceived compatibility as predicting perceived usefulness, and related knowledge as predicting perceived ease of use. The resulting model is empirically supported using a field survey of a computerized physician order entry system among 129 practicing physicians at a large acute-care hospital. Our study illustrates the importance of incorporating user resistance in technology usage studies in general and HIT usage studies in particular, grounds resistance research within extant theories of technology usage, and provides a preliminary model of resistance that can serve as the starting point for future research in this relatively unexplored yet potentially fertile area of research.
