User participation in the requirements engineering process: An empirical study

In the development of information systems, user participation in the requirements engineering (RE) process is hypothesised to be necessary for RE success. In this paper we develop a theoretical model which predicts that the interaction between user participation in the RE process and uncertainty has an impact on RE success. This theory is empirically tested using survey data. We develop instruments to measure user participation and uncertainty. An existing instrument for measuring RE success was used. This instrument covers two dimensions of RE success: (a) the quality of RE service, and (b) the quality of RE products. The results, indicate that as uncertainty increases, greater user participation alleviates the negative influence of uncertainty on the quality of RE service, and that as uncertainty decreases, the beneficial effects on the quality of RE service of increasing user participation diminish. Furthermore, we did not find that the interaction between user participation and uncertainty had an impact on the quality of RE products. Based on these results, we make recommendations for managing user participation in the RE process, and provide directions for future research.This work has been supported, in part, by the IT Macroscope Project and NSERC Canada.     

考虑移动群智感知用户类型的激励机制设计

An empirical study of information contribution to online feedback systems: A motivation perspective

Online feedback systems (OFSs) are increasingly available on online shopping websites; they allow consumers to post their ratings and consumption reviews for products. We employed motivation theory and a goal attainment perspective to model a set of motivating and inhibiting factors that could influence a consumer's intention to contribute to an OFS. Our experiment, which involved 168 university students, showed that a consumer's intention to contribute product reviews is influenced by perceived satisfaction gained in helping other consumers, perceived satisfaction gained in influencing the merchant, perceived probability of enhancing self-image, and perceived executional costs. In addition, the presence of an economic rewarding mechanism was found to promote a contribution when a consumer's perceived probability of enhancing self-image was relatively high or when perceived cognitive cost was relatively low. Implications of our findings are discussed.     

User acceptance of mobile commerce: an empirical study in Macau

This study aims to examine the positive and negative factors that can significantly explain user acceptance of mobile commerce (m-commerce) in Macau. A technology acceptance model for m-commerce with five factors is constructed. The proposed model is tested using data collected from 219 respondents. Confirmatory factor analysis is performed to examine the reliability and validity of the model, and structural equation modelling is performed to access the relationship between behaviour intention and each factor. The acceptance of m-commerce is influenced by factors including performance expectancy, social influence, facilitating conditions and privacy concern; while effort expectancy is insignificant in this case. The results of the study are useful for m-commerce service providers to adjust their strategies for promoting m-commerce services. This study contributes to the practice by providing a user technology acceptance model for m-commerce that can be used as a foundation for future research.     

Examining customers’ trust in online vendors and their dropout decisions: An empirical study

Customer dropouts represent a critical challenge to online vendors and have severely constrained the proliferation of electronic retailing, which greatly depends on the customer eventually clicking on the “confirm purchase” button. In this study, we investigate the relationship between customers’ trust in an online vendor and their dropouts in different stages of the purchase process. Using a well-established consumer decision-making process, we analyze salient online trust antecedents for each purchase stage, develop specific hypotheses, and test them empirically. Our results suggest that customers’ trust in an online vendor has significant effects on their decisions to exit from the vendor’s website, and that salient trust antecedents vary in different stages of the consumer decision process. According to our findings, customers by and large depend on general, subjective antecedents pertaining to personal traits or perceptions about the website’s ease of use to assess the trustworthiness of an online vendor in the early stages but focus on specific, objective, transaction-oriented antecedents directly related to their purchase decision making in the later stages. Our results have important implications for research and practice which are also discussed in the paper.     

Communication goals and online persuasion: An empirical examination

Computer-mediated communication (CMC) is frequently applied as a tool for organizational marketing and consumer research. This paper explores the underlying structure of message receivers’ communication goals and their impact on persuasiveness in the context of CMC. Extending prior research on the structure of primary and secondary goals, we identified five specific communication goals that are important to receivers. We conducted an online exercise in which subjects respond to a message requesting them to volunteer their time. The results demonstrate all five communication goals are important to one or more indicators of persuasiveness, including attitude toward the issue, source credibility, perceived information quality, and behavioral intention to comply with the request.     

Not all posts are treated equal: An empirical investigation of post replying behavior in an online travel community

The post replying behavior in online communities (OCs) has garnered little consideration, even though the feedback behavior represents the central social dynamic of OCs and greatly determines the vibrancy of OCs. To fill this gap, this study aims to identify major sharing post-related variables that explain the heterogeneity in the post replying behavior in knowledge sharing OCs. The research model is validated through a panel dataset assembled from an online travel community. The results reveal that sharing post length and vividness, contributors’ expertise and degree centrality, and members’ social interactions have significant associations with the number of replying posts.     

Product recommendation in online social networking communities: An empirical study of antecedents and a mediator

Intention to facilitate individual voluntary product recommendation in online social networking communities has attracted increased attention. However, it is not obvious why individuals recommend products in a community composed of non-transactional users. What are the critical factors influencing such a behavior? To attempt to provide insights into the product recommendation behavior in online social networking communities, we develop a model to investigate the effects of community atmospheric cues on affective social distance and subsequent product recommendations based on the stimulus–organism–response paradigm. By analyzing the results of a survey using a questionnaire, we found that community reciprocity and community receptivity have a direct influence on product recommendation, while community atmospheric cues have an indirect influence through affective social distance. Theoretical and managerial implications are discussed.     

User involvement in system design: An empirical test of alternative approaches

User involvement in the development of information systems is often assumed to be key to successful implementation. However, few empirical studies have clearly demonstrated a relationship between user involvement and two key indicators of system success: system usage and user information satisfaction. The authors test the general hypothesis that user involvement is a more complex concept than previous research would indicate; there are different types of involvement and different stages in the system development life cycle in which users may become involved. In a study of 83 users in 23 companies, they found that only the activity of user sign-offs on project phases had a significant correlation with both user information satisfaction and satisfaction with the information systems group. The authors conclude that there is a complex relationship between the type and degree of user involvement and other organizational and individual factors; this relationship affects both user satisfaction with and usage of the resulting systems. Some suggestions for further research taking this complexity into account are given.     

User experience and personal innovativeness: An empirical study on the Enterprise Resource Planning systems

Although user experience and personal innovativeness are two important factors in new technology adoption, there has been no prior study to test these factors with the Enterprise Resource Planning (ERP) adoption. This paper investigates moderating roles of user experience on the relationship between the personal innovativeness and the ERP adoption motivations. This issue is important because if the user has more experience with the systems then the power of influence of personal innovativeness on ERP adoption motivation would be different. Thus, this paper tests these important insights of ERP systems adoption with the two different field samples with high (more than three years) and low (less than three years) user experience, based on the innovation diffusion theory, self determination theory, and different types of motivations such as intrinsic and extrinsic motivations. The findings, based on the PLS analysis of the model using 107 ERP end users, show that there are clear moderating effects of user experience—such as impacts of personal innovativeness on ERP systems adoption motivations are higher in case of low user experience samples, as expected. Academic and practical implications are discussed in the paper based on these empirical findings.     

Data analytics and firm performance: An empirical study in an online B2C platform

Data analytics has become an increasingly eye-catching practice in both the academic and the business communities. The importance of data analytics has also prompted growing literature to focus on the design of data analytics. However, the boundary conditions for data analytics in creating value have been largely overlooked in the literature. The objective of this article therefore is to examine the business value of data analytics usage and explore how such value differs in different market conditions. We rely on an online B2C platform as our empirical setting and obtain several important insights. First, both demand-side and supply-side data analytics usage has a positive effect on the performance of merchants. Second, when merchants’ product variety is high, the influence of usage toward demand-side data on performance is strengthened, whereas such impact is weakened for supply-side data analytics. Third, when competitive intensity is high, the performance implication of demand-side data analytics usage is strengthened, whereas such impact is not strengthened for supply-side data analytics. This study contributes by advancing the overall understanding of business value of data analytics.     

Reference price effect and its implications for decision making in online auctions: An empirical study

Simultaneous supplies of an item by multiple online auction vendors greatly reduce the burden of arduous search that a consumer has to conduct in a brick-and-mortar market. The enriched information set endows all auction participants with added decision flexibility and complexity. One of such flexibilities or complications is the potential of information cross-referencing. In this study, we empirically tested if and how bidders interacted with each other through cross-referencing. Our results strongly supported the existence of cross-referencing. We also identified new strategies and tactical moves as best responses for sellers and bidders under the online simultaneous condition. This research provided another support for the path-dependent nature of online auctions as bidders were found to actively adjust their behavior in avoidance of winner's curse.     

Determinants of success for online communities: an empirical study

Although online communities can significantly facilitate collaboration among Internet users, the determinants of success of online communities have seldom been studied empirically. Using the updated DeLone and McLean information systems success model as a theoretical framework, this study proposes a research model to examine the determinants for successful use of online communities. Based on a survey of 165 community members, this study uses structural equation modelling (SEM) approach to investigate the research model. The analytical results strongly support the appropriateness of the research model in identifying the determinants of success of online communities. The analytical results also showed that system quality, information quality and service quality had a significant effect on member loyalty through user satisfaction and behavioural intention to use the online community. Finally, this study discusses the implications of these findings and offer directions for future research.

Community engagement and online word of mouth: An empirical investigation

How customer engagement in a firm’s social media marketing platform ? online brand community ? might affect word-of-mouth behavior is an open research issue as well as a vital business problem in e-commerce. To this end, we collected a set of longitudinal data that include community engagement behavior, e-commerce transactions, and customers’ post-purchase reviews. Using a control function approach, we find that consumer engagement in a brand community not only increases the likelihood of generating post-purchase reviews but also increases the likelihood of posting positive online reviews. Furthermore, we find that customer tenure has a positive moderating effect.     

Modeling hedonic is continuance through the uses and gratifications theory: An empirical study in online games

It has long been a challenge for online game providers that online game players frequently switch to alternative games without much hesitation. Current IS continuance theories are mainly developed to interpret user continuance of general utilitarian IS and are ineffective in interpreting user continuance of hedonic IS. In this study based on the uses and gratifications theory, a hedonic IS continuance model is developed by incorporating three types of gratification: hedonic gratification (enjoyment, fantasy and escapism); social gratification (social interaction and social presence); and utilitarian gratification (achievement and self-presentation). Age and gender are the moderating factors in the model. The research model is empirically assessed based on 3919 validated responses from the users of a social network game in China. In this study we found that three types of gratification affect an individual’s continuance intention to use a social network game: hedonic gratification (enjoyment, fantasy and escapism), utilitarian gratification (achievement) and social gratification (social interaction and social presence). The results provide weak support for the moderating effect of gender on the relationship between each antecedent and continuance intention, but offer strong support for the moderating effect of age on the relationships.     

An empirical study on consumer first purchase intention in online shopping: integrating initial trust and TAM

To understand the first purchase mechanism in online shopping, this study established an integrated model of initial trust and TAM. According to the analysis results, initial trust beliefs were significantly influenced by initial trust bases such as company reputation, structural assurance, and trusting stance, and initial trust beliefs indirectly influenced the first purchase intention through consumer attitude. In TAM constructs, only perceived usefulness directly influenced the usage attitude of online shopping systems, then indirectly influenced the first purchase intention. These results imply that online consumers consider perceived ease of use as a basic requirement for system design. It was also found that there is a time cushion between the time of first purchase and the time of belief formation. On the whole, these results reinforced the theory that a relationship between belief (trust and perceived usefulness) and intention was better explained when it was mediated by attitude.     

Design and evaluation of an adaptive incentive mechanism for sustained educational online communities

Most online communities, such as discussion forums, file-sharing communities, e-learning communities, and others, suffer from insufficient user participation in their initial phase of development. Therefore, it is important to provide incentives to encourage participation, until the community reaches a critical mass and “takes off”. However, too much participation, especially of low-quality can also be detrimental for the community, since it leads to information overload, which makes users leave the community. Therefore, to regulate the quality and the quantity of user contributions and ensure a sustainable level of user participation in the online community, it is important to adapt the rewards for particular forms of participation for individual users depending on their reputation and the current needs of the community. An incentive mechanism with these properties is proposed. The main idea is to measure and reward the desirable user activities and compute a user participation measure, then cluster the users based on their participation measure into different classes, which have different status in the community and enjoy special privileges. For each user, the reward for each type of activity is computed dynamically based on a model of community needs and an individual user model. The model of the community needs predicts what types of contributions (e.g. more new papers or more ratings) are most valuable at the current moment for the community. The individual model predicts the style of contributions of the user based on her past performance (whether the user tends to make high-quality contributions or not, whether she fairly rates the contributions of others). The adaptive rewards are displayed to the user at the beginning of each session and the user can decide what form of contribution to make considering the rewards that she will earn. The mechanism was evaluated in an online class resource-sharing system, Comtella. The results indicate that the mechanism successfully encourages stable and active user participation; it lowers the level of information overload and therefore enhances the sustainability of the community.     

Designing online audiovisual heritage services: an empirical study of two comparable online video services

The purpose of this study is to seek input for a new online audiovisual heritage service. In doing so, we assess comparable online video services to gain insights into the motivations and perceptual innovation characteristics of the video services. The research is based on data from a Dutch survey held among 1,939 online video service users. The results show that online video service held overlapping antecedents but does show differences in motivations and in perceived innovation characteristics. Hence, in general, one can state that in comparison, online video services comply with different needs and have differences in perceived innovation characteristics. This implies that one can design online video services for different needs. In addition to scientific implications, the outcomes also provide guidance for practitioners in implementing new online video services.
