Job performance through mobile enterprise systems: The role of organizational agility,location independence,and task characteristics

This study examines how organizational workers improve their perceived job performance through the use of Mobile Enterprise Systems (MES), while also investigating the impact of perceived organizational agility and location independence on technology acceptance of MES. This study also tests the moderating role of task characteristics (task significance and feedback) on the relationship between MES usage and perceived job performance. Based on the extant technology acceptance model (TAM), we proposed an extended TAM and conducted a large-scale survey among organizational workers who use MES in their workplace across industries. Our findings suggest that both positive attitude toward MES and a high level of habitual MES usage are positively associated with perceived job performance, and that task characteristics positively moderate the relationship between habitual usage (attitude toward MES) and perceived job performance. More importantly, we also found that organizational agility is positively associated with both perceived ease of use and perceived usefulness, while location independence is positively associated with perceived ease of use. The present findings provide us with a deeper understanding of how organizational workers utilize MES and how they improve their perceived job performance through the use of MES. Based on these findings, we discuss further implications and limitations.     

The effects of organizational learning environment factors on e-learning acceptance

Workplace learning is an important means of employees’ continuous learning and professional development. E-learning is being recognized as an important supportive practice for learning at work. Current research on the success factors of e-learning in the workplace has emphasized on employees’ characteristics, technological attributes, and training design elements, with little attention to workplace contextual effects. The study aims to investigate the impacts of organizational learning environment factors, including managerial support, job support, and organizational support, on employees’ motivation to use a workplace e-learning system. A model was proposed based on the expectancy theory of training motivation and the social influences and facilitating conditions in technology acceptance models. The model was tested on sample data collected from mainland China using Structural Equation Modeling and Moderated Structural Equation Modeling. The results suggested that employees’ perceived managerial support and job support had a significant impact on their perceived usefulness of the e-learning system for individual learning, and that perceived organizational support had a significant influence on the perceived usefulness of the e-learning system for social learning. Perceived usefulness for individual learning was found to completely mediate the environmental influences on individuals’ motivation to use the system, while perceived usefulness for social learning made partial mediation in the effects of the environmental factors on intention to use. In addition, perceived job support was found to have moderating effects on the relationship between employees’ perceived usefulness of the e-learning system and their intention to use the system. Consistent with previous findings, employees’ perceptions about the usefulness of the e-learning system have significant effects on their intention to use the system in the work setting.     

The relationship between information technology acceptance and organizational agility in Malaysia

We examined the influence of information technology (IT) acceptance on organizational agility. The study was based on a well-established theoretical model, the Technology Acceptance Model (TAM). We attempted to identify the relationships between IT acceptance and organizational agility in order to see how the acceptance of technology contributes to a firm's ability to be an agile competitor. Structural equation modeling techniques were used to analyze the data. Results from a survey involving 329 managers and executives in manufacturing firms in Malaysia showed that actual system or technology usage had the strongest direct effect on organizational agility. Meanwhile, perceived usefulness and perceived ease of use of IT influenced organizational agility indirectly through actual systems or technology use and attitudes towards using the technology. The results have several implications for IS management.     

A model of organizational employees’ e-learning systems acceptance

This study examines the factors that influence employees’ adoption and use of e-learning systems and tests the applicability of the technology acceptance model (TAM) in the organizational context. We examined the relationship of employees’ perceptions of their behavioral intention to use e-learning systems in terms of four determinants (individual, organizational, task characteristics, and subjective norm), to further explore the effects of management and organizational support on the subjective norm. Data were 357 valid questionnaires from four industries in Taiwan. The findings indicate that organizational support and management support significantly affected perceived usefulness and intention to use. Individuals’ experience with computers and computer self-efficacy had significantly positive effects on perceived ease of use. Task equivocality significantly influenced perceived usefulness. Organizational and management supports significantly impacted the subjective norm, perceived usefulness, perceived ease of use, and intention to use. Additionally, the results suggest that external variables that affect perceived usefulness, perceived ease of use, and intention to use, need to be considered as important factors in the process of designing, implementing, and operating e-learning systems. The results provided a more comprehensive insight of individual, organizational, and task characteristics in predicting e-learning acceptance behavior in the organizational contexts, rarely tested in previous studies. By considering these identified factors, practitioners can take corresponding measures to predict or promote organizational employees’ e-learning systems acceptance more effectively and efficiently. Furthermore, by explaining employees’ acceptance behavior, the findings of this research help to develop more user-friendly e-learning systems and provide insight into the best way to promote e-learning systems for employees.     

Understanding information proactiveness and the content management system adoption in pre-implementation stage

The overall technology acceptance literature does not pay sufficient attention to the issue of the mandated use of systems as the traditional acceptance models (e.g. TAM) were originally built, tested, and validated by being applied to technologies that were mainly voluntary in nature, that is, the users had the choice of whether to use or not use the technology. Few have studied end users' proactive motivation to use information and attitude toward newly implemented technologies within organizational contexts, before end-users start using the technology or pre-implementation stage. This research proposes that information proactiveness has influences on the content management systems adoption beliefs such as perceived ease of use and perceived usefulness. The proposed model was empirically tested using the data collected from content management systems end-users. As theorized, information proactiveness was found to be a significant determinant of system users' perceived ease of use but not perceived usefulness in pre-implementation stage. Furthermore, perceived behavioral control was found to be a strong determinant of systems users' attitude. The study findings provide important insights on enhancing system users' adoption behavior in pre-implementation stage.     

Determinants of users’ intention to adopt wireless technology: An empirical study by integrating TTF with TAM

This paper reported the results of a survey study and provided evidences of empirically testing a model that integrates both technology acceptance model (TAM) and task-technology fit (TTF) model in understanding the determinants of users’ intention to use wireless technology in organizations. Questionnaires were distributed to organizations that bring mobile commerce into practice through the wireless handheld devices. The results indicated that both technology acceptance model and task-technology fit model are robust models by themselves. First, both perceived usefulness and ease of use significantly influence users’ behavior intention to utilize wireless technology. Perceived ease of use has significant effect on perceived usefulness. Second, characteristics of technology and task significantly predict the fit between these two constructs. Significant effect of characteristics of technology on perceived ease of use and usefulness were observed. Finally, significant relationships between TAM and TTF model were also observed. Task-technology fit is a significant direct predictor of technology adoption intention. Overall, users’ intention to adopt wireless technology in organizations was determined directly by fit between characteristics of task and technology as well as users’ perceived ease of use and usefulness.     

Convenience and TAM in a ubiquitous computing environment: The case of wireless LAN

Ubiquitous computing technology is seen as an emerging new information technology with such potency that it has changed the way we view IT. Although perceived ease of use and perceived usefulness constructs have been considered important in determining the individuals’ acceptance and use of IT in the last few decades, factors contributing to the acceptance of a new IT are likely to vary according to the technological characteristics, the target users, and the context.In this study, we will introduce convenience as a new factor that reflects the characteristic of ubiquitous computing technology. In addition, we chose wireless LAN as an initial stage technology of ubiquitous computing to empirically validate the extended technology acceptance model (TAM) applied in a ubiquitous computing environment.     

Predicting user satisfaction,strain and system usage of employee self-services

In this study, we explore attitudinal and behavioural patterns when using employee self-service (ESS) systems by using an expanded technology acceptance model (TAM). We examine the relationship between organizational support and information policy on the one hand and ease of use and usefulness on the other, and then the relationship between ease of use and usefulness with satisfaction, strain and system usage. To explore question order effects, user satisfaction was assessed prior to or after survey items. Data was collected from 517 employees using an ESS system. Results from partial least squares structural equation modelling suggests that (a) organizational support and information policy were positively related to ease of use, (b) usefulness was positively related to satisfaction and system usage, (c) ease of use and usefulness were negatively related to user strain and (d) ease of use fully mediates the relation between organizational support and strain as well as between information policy and strain. Evidence for a question order effect was found with increased satisfaction judgements, when satisfaction was assessed after the survey items. Results are discussed in terms of the theoretical and methodological aspects of the TAM and their implications for ESS system implementation.     

The impact of role stress fit and self-esteem on the job attitudes of IT professionals

We used person–job fit theory to examine the relationships between the match in IT developers’ preferred and perceived actual role stress (role stress fit) with job satisfaction and organizational commitment. Self-esteem was considered as either a potential moderator or mediator of those relationships. Results from surveys completed by IT developers in 12 Fortune 500 companies indicated that role stress fit was positively related to both job satisfaction and organizational commitment and that self-esteem significantly moderated the relationship between role stress fit and job satisfaction. The results of our research has provided insight into staff assignment and the design of coping interventions.     

Extended technology acceptance model of Internet utilization behavior

Based on the belief–attitude–performance chain, this study combines Davis’s technology acceptance model (TAM) and the information behavior model to develop an extended TAM for Internet use. The theoretical model was tested via a questionnaire survey of 203 Taiwanese office workers. The empirical results not only confirmed TAM, but also showed that the relevance of information needs strongly determines perceived usefulness, perceived ease of use, and user attitudes toward Internet use for information seeking, as well as strongly influencing individual performance during the information use stage. More importantly, relevance has greater positive effect on perceived performance and perceived usefulness for enterprise Intranet users than for simple/interactive Intraweb users. Enterprise Intranet users have more positive attitudes toward the Internet and more positive perceptions of system effectiveness for supporting office tasks than simple/interactive Intraweb users. Furthermore, perceived ease of use is the strongest determinant of user attitude toward Internet use in both enterprise Intranet and simple/interactive Intraweb applications. Overall, the extended TAM explains the behavior of enterprise Intranet users better than that of simple/interactive Intraweb users. Limitations of this study are discussed.     

Determinants of students’ continuance intention to use blogs to learn: an empirical investigation

This study examines factors influencing students’ continuance intention to use blogs to learn in an undergraduate-level course. The research uses constructs from relevant theoretical frameworks, including the technology acceptance model, social cognitive theory, innovation diffusion theory, and expectation–confirmation model. A survey administered to 108 university students in a Canadian university was analysed using the partial least squares technique. The results show that perceived usefulness and perceived compatibility have positive effects on students’ attitudes towards blog use; perceived ease of use did not. Perceived compatibility, perceived self-efficacy, and perceived support for enhancing social ties with blogs have significant effects on the positive impacts of learning with such tools. Attitude and positive impacts of learning with blogs influence satisfaction with blog use. Both attitude and satisfaction are determinants of students’ continuance intention to use blogs to learn. Satisfaction with blog use is the main predictor of continued use intention.     

The acceptance and use of a virtual learning environment in China

The success of a virtual learning environment (VLE) depends to a considerable extent on student acceptance and use of such an e-learning system. After critically assessing models of technology adoption, including the Technology Acceptance Model (TAM), TAM2, and the Unified Theory of Acceptance and Usage of Technology (UTAUT), we build a conceptual model to explain the differences between individual students in the level of acceptance and use of a VLE. This model extends TAM2 and includes subjective norm, personal innovativeness in the domain of information technology, and computer anxiety. Data were collected from 45 Chinese participants in an Executive MBA program. After performing satisfactory reliability and validity checks, the structural model was tested with the use of PLS. Results indicate that perceived usefulness has a direct effect on VLE use. Perceived ease of use and subjective norm have only indirect effects via perceived usefulness. Both personal innovativeness and computer anxiety have direct effects on perceived ease of use only. Implications are that program managers in education should not only concern themselves with basic system design but also explicitly address individual differences between VLE users.     

The impact of information technology on individual and firm marketing performance

The perceived impacts of information technology use on firm marketing organization performance are examined. A theoretical model is presented linking organizational and end-user traits, information quality, system/service quality, industry traits, and tasks performed using a system to perceptions of organizational performance impacts through ease of system use, perceived individual performance impacts (i.e. perceived usefulness), attitudes toward using the system, and system use. The empirical examination uses a mail survey of US marketing executives to collect the data. The quantitative technique used is structural equation modeling. The results indicate that measures of organizational traits, individual traits, information quality, system/service quality, and tasks performed using the system impact perceived performance of the marketing organization mediated individual performance impacts (i.e. perceived usefulness), attitudes toward using the system, and system use. Managerial implications and conclusions are presented based upon these results.

A structural equation modeling of the Internet acceptance in Korea

The objective of this study is to develop and test an integrated conceptual model of the Internet acceptance. Based on the two dominant theoretical paradigms – the theory of reasoned action (TRA) and the technology acceptance model (TAM) – we propose a model of the Internet acceptance to investigate the relationship between external variables such as individual differences, task characteristics and management support, and individual acceptance of the Internet. The model is tested using data gathered from 374 end users of the Internet in Korean firms and data analysis is conducted using a structural equation modeling with LISREL. Significant relationships are found between experience and usefulness, between experience and ease of use, and between ease of use and usefulness. Organizational support is found to influence usefulness, ease of use and subjective norm. We also observe that actual usage is not influenced by subjective norm, but significantly influenced by experience, usefulness and ease of use. This result implies that individual acceptance of the Internet is significantly related to external factors such as experience, task characteristics and organizational characteristics rather than beliefs.

Impact of media richness and flow on e-learning technology acceptance

Advances in e-learning technologies parallels a general increase in sophistication by computer users. The use of just one theory or model, such as the technology acceptance model, is no longer sufficient to study the intended use of e-learning systems. Rather, a combination of theories must be integrated in order to fully capture the complexity of e-learners, who are both system users and learners. The current research presents an integrated theoretical framework to study users’ acceptance of streaming media for e-learning. Three streams of research provide the basis for this integrated framework: the technology acceptance model, flow theory and media richness theory. Students enrolled in an online section of an information systems course used one of three different combinations of text, streamed audio and streamed video. Regression analysis was used to test the hypotheses in this field experiment. Perceived ease of use was a predictor of perceived usefulness; both the perceived usefulness and the attitude of the user were predictors of intention to use. Richer content-presentation types were positively correlated with higher concentration levels but showed mixed results when correlated with perceived usefulness. Results from this study have practical implications for those interested in integrating streaming media into e-learning.     

Explaining physicians’ acceptance of EHCR systems: An extension of TAM with trust and risk factors

This paper explains physicians’ acceptance, in terms of usage intentions, of a central component of health information technology: electronic health care records (EHCR systems). For this purpose, the original version of the Technology Acceptance Model (TAM), which included perceived usefulness, perceived ease of use, attitude towards usage, and usage intentions, is extended with trust and risk-related factors such as physicians’ perceptions of institutional trust, perceived risk, and information integrity. The results stress the special importance of attitudinal factors (attitude towards usage and perceived institutional trust) and cognitive instrumental processes (mainly, usefulness perceptions) in determining physicians’ intention to use EHCR systems. Perceptions of institutional trust exerted strong direct effects on physicians’ perceived usefulness, perceived ease of use, and attitude towards the use of EHCR systems. In addition, trust fully mediated the influences of perceived risk and information integrity perceptions on physicians’ acceptance of EHCR systems.     

Extending the TAM for a t-commerce

Broadband communication at home allows television to become an e-commerce medium that merges video, voice, and transactional data. t-commerce is electronically mediated commerce using interactive television. Theoretical and empirical analysis was undertaken and reported here to explain the factors that influence potential users’ adoption of t-commerce by extending the technology acceptance model. The study also compared the factors influencing t-commerce adoption between experienced and inexperienced users. Seven factors were identified: perceived ease of use, perceived usefulness, perceived enjoyment, trust, attitude, normative belief of family and friends, and subjective norm. Although the factors were not the same between the two groups, the differences were not large. Perceived enjoyment is the most important factor affecting attitude and behavioral intention toward t-commerce. From a theoretical point of view, the study extended the TAM for t-commerce adoption by potential users in the home environment. Moreover, this study also provided practical implications for t-commerce providers.     

Design and validation of a knowledge map system—the case of construction industry in Taiwan

Knowledge map systems (KMSs) have recently received widespread attention. A review of the literature shows that relatively few studies explicitly address the issues of implementation and user evaluation of the system and are limited in application. In view of this dilemma, this study aims to integrate the key features of knowledge assets maps, knowledge sources maps, knowledge structure maps, and knowledge task maps in order to develop an operational KMS. Also, the technology acceptance model was used as the theoretical basis for the assessment of user acceptance of the system, which is validated using structural equation modeling. In terms of user acceptance assessment, our empirical results shows that the perceived usefulness and perceived ease of use will positively affect user attitude toward the proposed KMS. Also, our results suggest that social defense negatively moderates the effect of attitude toward the system on behavior intention. Furthermore, we found that the management system also positively moderates the effect of attitude toward the system on behavior intention. On the basis of theoretical evaluation and empirical investigation, we hope that the proposed construction of a knowledge system can serve as references for both academic and related practical fields.
