The intention–behaviour gap in technology usage: the moderating role of attitude strength

Extant theories of information technology (IT) usage present users' behavioural intention as the primary predictor of their IT usage behaviour. However, empirical evidence reveals only a low-to-medium effect size for this association. We call this inconsistency the ‘intention–behaviour gap’, and argue that a clearer understanding of this gap requires a deeper theoretical examination of the conditions under which intentions may or may not influence behaviour. Drawing on recent attitude theoretic research in social psychology, we distinguish between two types of attitudes – strong versus weak – and suggest that the intention–behaviour association may hold for users with strong attitudes but is likely to be weaker for those with weak attitudes. Using the elaboration-likelihood model, we propose two dimensions of attitude strength relevant to the IT usage context – personal relevance and related expertise – and theorise them to moderate the intention–behaviour association in a positive manner. Results from a longitudinal field survey of document management system usage among governmental employees at L'viv City Hall, Ukraine support our theoretical hypotheses. Theoretical and practical implications of our findings are discussed.     

Information technology (IT) in Saudi Arabia: Culture and the acceptance and use of IT

The unified theory of acceptance and use of technology (UTAUT), a model of the user acceptance of IT, synthesizes elements from several prevailing user acceptance models. It has been credited with explaining a larger proportion of the variance of ‘intention to use’ and ‘usage behavior’ than do preceding models. However, it has not been validated in non-Western cultures. Using a survey sample collected from 722 knowledge workers using desktop computer applications on a voluntary basis in Saudi Arabia, we examined the relative power of a modified version of UTAUT in determining ‘intention to use’ and ‘usage behavior’. We found that the model explained 39.1% of intention to use variance, and 42.1% of usage variance. In addition, drawing on the theory of cultural dimensions, we hypothesized and tested the similarities and differences between the North American and Saudi validations of UTAUT in terms of cultural differences that affected the organizational acceptance of IT in the two societies.     

Exploring the effects of direct experience on IT use: An organizational field study

Empirical studies have investigated the effect of attitude and behavior on IT acceptance in organizations but yielded ambiguous results. Possibly they have not effectively accounted for the moderating effects of experience gained through direct interaction with the target technology. We examined the moderating effect of the length of direct experience on IT acceptance relationships and constructs. Using multi-group invariance analysis, we demonstrated that relationships between key IT acceptance constructs differed, depending on the user's experience. The incorporation of direct experience can lead to convergent results and contribute to further understanding of the process. We discuss some implications from the knowledge that IT use is a dynamic process and suggest that IT management must account for direct experience in their decision making.     

Information technology capability and firm performance: Role of industry

Despite several calls for considering industry in the IS value research, few studies investigated the relationship between benefits of IT and industries. This study extends Chae et al. (2014) by investigating how industry influences the relationship between IT capability and business performance. Unexpectedly, it finds that the control group in the industries in which the "transform" IT strategic role dominates showed superior performance than the IT leader. Also, the IT leaders in the "automate" IT strategic industry did not exhibit better business performance than the control firms. We discuss the implications of these findings.

Behavioral Analysis of E-commerce Acceptance in Micro-enterprises简

E-commerce present opportunities and challenges for businesses, especially for micro-enterprises. This paper proposed a theoretical framework that in line with the unique characteristics of E-commerce acceptance in micro-enterprises in Chengdu, which is based on the unified theory of acceptance and use of technology （UTAUT） model. The extending UTAUT model includes key constructs of performance expectation, perceived behavioral control and the characteristics of owner-managers.     

The role of perceived organizational support,distributive justice and motivation in reactions to new information technology

Despite tremendous investments in information technology (IT), many technological interventions in organizations fail because employees do not fully accept and use IT. The present study explored how perceived organizational support and distributive justice affect employee reactions to new IT from a motivational point of view. Self-determination theory was used to understand how different motivational styles, varying in degree of self-determination, mediate the relationship of perceived organizational support and distributive justice with reactions to new IT. Results showed that perceived organizational support and distributive justice were associated with intrinsic and identified motivation to use the IT, but only POS was related to enjoyment and acceptance of the IT. Intrinsic and extrinsic motivation were both associated with IT usage, but IT usage was associated with enjoyment and acceptance only when people were intrinsically motivated. Intrinsic motivation also mediated the effects of POS on enjoyment and acceptance. Moreover, intrinsically motivated users were less likely to use a paper-based appointment booking alternative than those who were not. Implications for managing IT implementations are discussed.     

Identifying the ideal fit between mobile work and mobile work support

The rapid growth in the use of wireless communication and portable devices has created a potential for a variety of mobile work support. However, few studies have explored the nature of mobile work, examined the needs for its support, and identified the appropriate support for various kinds of work in mobile contexts. In our study, a mobile task model was proposed and tested, including three dimensions: mobility, location dependency, and time criticality. Four context-related mobile work support functions were examined: location tracking, navigation, notification, and online job dispatching. In the light of task-technology fit theory and attitude/behavioral theory, we proposed a research model for the fit between task characteristics and the four mobile work support functions. The ideal fit was analyzed on the basis of empirical data collected from a sample of mobile knowledge and field workers. Our study resulted in a theoretical contribution to task/technology fit theory in the context of mobile work support, and suggested guidelines for the development and use of mobile work support systems.     

A strategic path to study IT use through users’ IT culture and IT needs: A mixed-method grounded theory

We consider recent research in IS, as well as recent advances in the fields of psychology and sociology. As an alternative to existing models, we propose a new strategic path to study IT use through users’ IT culture and IT needs. Our contributions are (1) theoretical: we investigate the predictive value for IT usage of several new constructs and show that both expectancy-based and needs-based theories of motivation should be taken into account in acceptance models, (2) methodological: we adopt an exploratory, mixed-method, grounded theory approach and use both quantitative and qualitative data and methods, an unusual approach in IS research that allows new perspectives, and (3) practical: our results highlight the fact that highly IT-acculturated users may hinder (rather than facilitate) new-IT acceptance if their situational IT needs are ignored. Therefore, when the strategic decision of implementing new IT is made, managerial attention must be focused on these users in order to drive toward the alignment of their IT needs and managerially-perceived organizational IT needs.Our work opens the way to numerous avenues for future research.     

A Process-Centered IT ROI Analysis with a Case Study

In order to achieve a meaningful IT ROI (Returns of Investment) analysis while taking into account the unique business processes of each industry, we should conduct research into a system to evaluate the effect of investment. In this paper, through careful consideration of the characteristics of the banking industry, a study on IT ROI is conducted from the perspective of business process. The process-centered IT ROI model for analysis discussed here consists of seven phases. The suggested model is explained and verified with a case study of a finance company that we shall call A.     

Acceptance of online banking information systems: an empirical case in a developing economy

This paper proposes an extended model of technology acceptance to understand potential users’ acceptance of online banking information systems (OBIS). The proposed model integrates key constructs from information systems and e-commerce acceptance research streams into the theoretical frame of the technology acceptance model. The model was tested on a sample of 353 Internet banking users in Pakistan. Using structural equation modelling with Analysis of Moment Structures software, data analysis showed considerable support for the extended hypothesised model. The results suggested that, in order of importance: perceived usefulness (PU), perceived ease of use (PEOU) and trust explained 45.7% of the variance in intended acceptance behaviour. Trust and technological self-efficacy (TSE) predicted 28.1% of the variance in PU. While in PEOU 21.8% of the variance was predicted by TSE, accessibility and terminology clarity. This study produced valuable insights into the factors that influence acceptance of OBIS by intended users and offers new ideas in understanding the acceptance of technology, especially in developing countries.
