ASSESSING INFORMATION SYSTEM VALUE: AN EXPERIMENTAL STUDY

The Determinants for Food Safety Push Notifications on Continuance Intention in an E-Appointment System for Public Health Medical Services: The Perspectives of UTAUT and Information System Quality

Compared to other appointment methods in public hospitals, registering through the Internet or utilizing e-appointments, or registering online as an outpatient, can provide more information to the user. This research investigated the integration of unified theory of the acceptance and use of technology and information system quality in determining factors that influence the adoption of e-appointments by patients, based on the requirements of food safety consultation in Taiwan. Empirical data from 369 valid samples were assessed using Partial Least Squares (PLS). The key findings of this study indicated that patients’ acceptance of e-appointments was influenced by users’ perceptions (i.e., performance expectancy and facilitating conditions), along with information quality and service quality. The practical and academic implications are provided for future practitioners and scholars, and to enhance patients’ usage of e-appointments in their healthcare activities.

Strategic value of RFID for inter-firm supply chain networks

Despite the huge potential benefits of radio frequency identification (RFID) in collaborative use with transaction partners, many companies are reluctant to implement RFID with their partners and skeptical of its strategic value in inter-firm, supply chain networks. However, existing research is concentrated on the internal adoption and benefit measurement of RFID system, without careful consideration of the strategic value in an inter-organizational context at implementation stage. Hence, this study empirically identifies the reciprocal strategic value of RFID implementation in inter-firm, supply chain networks based on the resource-based theory and social capital theory. Additionally, mutual quality constructs of RFID system from an inter-organizational context are investigated as determinants of the strategic value. Empirical results have shown that supply chain visibility and agility are improved through high-level, shared information quality and inter-organizational system quality of RFID. Inter-organizational trust is enhanced by high-level, inter-organizational service quality and supply chain agility. Moreover, all strategic values of RFID (visibility, agility, and trust), when enhanced by RFID, have positive impacts on supply chain performance. This study expands the discussion scope of RFID to the implementation stage at the inter-firm level beyond the internal adoption level, improving the delay of RFID diffusion among transaction partners. Furthermore, the study describes strategic points that can be used to maximize the RFID value in supply chain networks.

The Role of Information Quality of a Website

Understanding the nature of information quality in the context of consumer information search on a website is vital for Information Systems as well as for marketing managers who want to use their websites for strategic purposes. This study brings together the Information Systems (IS) Success Model and consumer information search literature to propose and test a comprehensive model investigating information quality, and extends the IS Success Model. Our model tests antecedents to and consequences of information quality of a website. Findings on data collected from 575 respondents reveal that perceived cost and self efficacy (among others) are significant antecedents to information quality. Findings also reveal that information quality significantly affects online WOM and trust, which has implications for managing users on social media as well as on websites. This study adds to the literature on IS and on consumer information search, and offers practical guidelines for managers.

The sustainability of corporate wikis

While existing theoretical frameworks describe collective technology adoption patterns, they provide little insight regarding the expected patterns of wiki activity within projects. Another impediment to the study of wiki sustainability is the absence of time-series analysis methods that are suitable for the unique patterns of wiki activity logs. The primary goals of this study are to: (i) develop a novel method for analyzing wiki edit activity logs, (ii) reveal the temporal patterns of corporate wiki edit activity, and (iii) study the factors impacting wikis' sustainability. A validation of our proposed method demonstrates that it is superior to the baseline algorithm in the face of noisy data. Our empirical study combines wiki system edit activity logs with a survey of users' perceptions, and explores 33277 distinct wiki applications within one global organization over the first 5 years of wiki operation. Our results reveal six different prototypical wiki activity patterns, and show that most corporate wikis become inactive after a relatively short period. Findings from the user survey show that users of sustainable wikis are more satisfied with the wiki system and its contents, and feel that the wiki provides them with a sense of community and productivity enhancements.

Measuring mobile patient safety information system success: an empirical study

OBJECTIVE

The Health Risk Reminders and Surveillance (HRRS) system was designed to deliver critical abnormal test results of severely ill patients from Laboratory, Radiology, and Pathology departments to physicians within 5 min using cell phone text messages. This paper explores the success of the HRRS system.

METHOD

This study employed an augmented version of the DeLone and McLean IS success model. Seven variables (system quality, information quality, system use, user satisfaction, mobile healthcare anxiety, impact on the individual and impact on the organization) were used to evaluate the success of the HRRS system. The interrelationships between the seven variables were hypothesized and the hypotheses were empirically tested.

RESULTS

The results indicate that the information quality of the HRRS system is positively associated with both system use and user satisfaction. In addition, system use is positively associated with user satisfaction, which is also positively associated with mobile healthcare anxiety. Moreover, results indicate that impact on the individual is positively associated with both user satisfaction and mobile healthcare anxiety. Finally, the impact of the organization is positively associated with impact on the individual.

CONCLUSION

The results of the study provide an expanded understanding of the factors that contribute to mobile patient safety information system (IS) success. Implications of the relationship between system use and physician mobile healthcare anxiety are discussed.

The perceptual evaluation of information systems using the construct of user satisfaction

This research work concerns the perceptual evaluation of the performance of information systems (IS) and more particularly, the construct of user satisfaction. Faced with the difficulty of obtaining objective measures for the success of IS, user satisfaction appeared as a substitutive measure of IS performance (DeLone & McLean, 1992). Some researchers have indeed shown that the evaluation of an IS could not happen without an analysis of the feelings and perceptions of individuals who make use of it. Consequently, the concept of satisfaction has been considered as a guarantee of the performance of an IS. Also it has become necessary to ponder the drivers of user satisfaction. The analysis of models and measurement tools for satisfaction as well as the adoption of a contingency perspective has allowed the description of principal dimensions that have a direct or less direct impact on user perceptions

The case study of a large French group, carried out through an interpretativist approach conducted by way of 41 semi-structured interviews, allowed the conceptualization of the problematique of perceptual evaluation of IS in a particular field study. This study led us to confirm the impact of certain factors (such as perceived usefulness, participation, the quality of relations with the IS Function and its resources and also the fit of IS with user needs). On the contrary, other dimensions regarded as fundamental do not receive any consideration or see their influence nuanced in the case studied (the properties of IS, the ease of use, the quality of information). Lastly, this study has allowed for the identification of the influence of certain contingency and contextual variables on user satisfaction and, above all, for the description of the importance of interactions between the IS Function and the users

An empirical study on the impact of quality antecedents on tax payers' acceptance of Internet tax-filing systems

This study used the Technology Acceptance Model (TAM) to examine taxpayers' acceptance of the Internet tax-filing system. Based on data collected from 141 experienced taxpayers in Taiwan, the acceptance and the impact of quality antecedents on taxpayers' perceived usefulness (PU) and perceived ease of use (PEOU) of the system were assessed and evaluated. The results indicated that the model of Internet tax-filing system was accepted with a reasonable goodness-of-fit. Three important findings include the following items. First, TAM proves to be a valid model to explain the taxpayers' acceptance of the Internet tax-filers' system. Meanwhile, PU has created more impact than PEOU on taxpayers' intention to use the system. Second, PU is positively influenced by such factors as information system quality (ISQ), information quality (IQ), as well as perceived credibility (PC). Third, IQ has a positive impact on PEOU. Based on the research findings, implications and limitations are then discussed for future possible research.

What users want in e-commerce design: effects of age, education and income

Preferences for certain characteristics of an online shopping experience may be related to demographic data. This paper discusses the characteristics of that experience, demographic data and preferences by demographic group. The results of an online survey of 488 individuals in the United States indicate that respondents are generally satisfied with their online shopping experiences, with security, information quality and information quantity ranking first in importance overall. The sensory impact of a site ranked last overall of the seven characteristics measured. Preferences for these characteristics in e-commerce sites were differentiated by age, education and income. The sensory impact of sites became less important as respondents increased in age, income or education. As the income of respondents increased, the importance of the reputation of the vendor rose. Web site designers may incorporate these findings into the design of e-commerce sites in an attempt to increase the shopping satisfaction of their users. Results from the customer relationship management portion of the survey suggest that current push technologies and site personalization are not an effective means of achieving user satisfaction.

I/S attitudes: toward theoretical and definitional clarity

There has long been a recognized need to measure the "success" or efficacy of information systems and the implementation process. Various constructs related to success have been suggested such as user attitudes, use, performance, and value. The attitude construct has received a great deal of attention for both theoretical and operational reasons. This paper focuses on the need for a convincing theoretical model linking systems or policies and user attitudes on the one hand, and user attitude and performance or value on the other. Using job satisfaction research as a reference discipline for understanding the relationship between attitudes and performance, a model of I/S attitudes, beliefs, and performance is developed. This model suggests that performance is affected by the correspondence or "fit" between the task requirements and the functionality of the I/S environment. In addition a distinction between beliefs and attitudes is recommended. While satisfaction might be best determined by measuring attitudes, the correspondence between task and functionality is best determined by measuring beliefs. The implications of this model for future research are discussed.
