Understanding determinants of information systems users’ behaviour: a comparison of two models in the context of integrated accounting and budgeting software

This study examines determinants that affect the behaviour of information systems (IS) users, and influence of the users’ decisions to continue using IS by two models: the technology acceptance model (TAM) and the expectation-confirmation model of IS continuance (ECM-IS). The behaviour of professionals who utilise complex software solutions for performing their working tasks has been in the focus of this research. Based on data gathered from questionnaires filled-out by users of the integrated accounting and budgeting software (IABS), the confirmatory factor analysis has shown that both models demonstrate good factor, convergence and discriminatory validity, respectively. The comparison of the obtained results has been performed, and it shows that ECM-IS has a larger explanatory power (R²) over TAM, explaining 49% of the dependent variable (IS continuance intention) in relation to 29%. The IS continuance intention is determined by the users’ satisfaction and perceived usefulness. The user satisfaction is influenced by perceived usefulness and confirmation. The confirmation of the user's expectations has had a positive influence on perceived usefulness. The perceived ease of use has not exerted a significant influence on the user's intention of IS continuance.     

Relative importance of evaluation criteria for enterprise systems: a conjoint study

Abstract.  While a large body of research exists on the development and implementation of software, organizations are increasingly acquiring enterprise software packages [e.g. enterprise resource planning (ERP) systems] instead of custom developing their own software applications. To be competitive in the marketplace, software package development firms must manage the three-pronged trade-off between cost, quality and functionality. Surprisingly, prior research has made little attempt to investigate the characteristics of packaged software that influence management information system (MIS) managers' likelihood of recommending purchase. As a result, both the criteria by which MIS managers evaluate prospective packaged systems and the attributes that lead to commercially competitive ERP software products are poorly understood. This paper examines this understudied issue through a conjoint study. We focus on ERP systems, which are among the largest and most complex packaged systems that are purchased by organizations. In a conjoint study, 1008 evaluation decisions based on hypothetical ERP software package profiles were completed by managers in 126 organizations. The study represents the first empirical investigation of the relative importance that managers ascribe to various factors that are believed to be important in evaluating packaged software. The results provide important insights for both organizations that acquire such systems and those that develop them. The results show that functionality, reliability, cost, ease of use and ease of customization are judged to be important criteria, while ease of implementation and vendor reputation were not found to be significant. Functionality and reliability were found to be the most heavily weighted factors. We conclude the paper with a detailed discussion of the results and their implications for software acquisition and development practice.     

An empirical investigation on factors affecting the acceptance of CASE by systems developers

This paper presents the findings of an empirical study of factors affecting the acceptance of CASE by systems developers. Based on two research models (technology acceptance and personal computer utilization) recently published in IS literature, an integrated model which consists of six variables and incorporates key elements of both models was developed to examine determinants of CASE acceptance. The findings indicate that ease of use has the largest influence on CASE acceptance, followed by long-term consequences. Both transitional support and near-term usefulness do not have a significant direct effect on the acceptance but exhibit their indirect influence through ease of use and/or long-term consequences. The implementation gap was found to have a relatively small and negative effect on CASE acceptance through its influence on ease of use, near-term usefulness, and long-term consequences. Implications of the findings, from both a research and a managerial perspective are discussed in this paper.     

Is traditional,open-source,or on-demand first choice? Developing an AHP-based framework for the comparison of different software models in office suites selection

Until recently, organizations planning to acquire application software (AS) have had no choice but to adopt proprietary, on-premises software. With the advent of open-source and on-demand solutions, new models for developing and distributing software have entered the stage providing IS managers with more options in AS selection. On the basis of an Analytic Hierarchy Process model, we propose a framework including software package and implementation attributes on different hierarchy levels to examine how IS managers evaluate the relative fulfilment of key selection criteria by traditional, open-source, and on-demand office suites. By testing the framework with a random sample of 254 IS managers of 166 smaller and 88 mid-sized/larger firms, we validate its validity and usefulness in evaluating different software delivery models. Our empirical results show that open-source office suites were consistently perceived to be superior in meeting ease of customization (i.e., extensibility and adaptability) and cost criteria (i.e., acquisition and maintenance cost), whereas traditional software models were superior in fulfilling functionality, ease of use, and support requirements. On-demand office suites excelled in the fulfilment of time-to-value and data recoverability. We discuss further results of the comparison of the three software models, and derive practical and research implications for office suite selection.     

The relation of interface usability characteristics,perceived usefulness,and perceived ease of use to end-user satisfaction with enterprise resource planning (ERP) systems

Over the past few years, firms around the world have implemented enterprise resource planning (ERP) systems to have a standardized information system (IS) in their respective organizations and to reengineer their business processes. While millions of dollars have been spent on implementing ERP systems, previous research indicates that potential users may still not use them. This study, based on data from 51 end-users in 24 companies examines various usability factors affecting end-user satisfaction with ERP systems. The results indicate that both perceived usefulness and learnability are determinants of end-user satisfaction with ERP systems. In addition perceived ease of use and system capability affect perceived usefulness, while user guidance influences both perceived usefulness and learnability. Implications of these findings are discussed and further research opportunities described.     

Understanding driver adoption of car navigation systems using the extended technology acceptance model

This study proposes an integrated research model for investigating driver adoption of car navigation systems. We consider the potential causal connections between core cognitive and psychological factors and driver intention to use these systems. We extracted possible factors that may significantly affect the perceived usability of car navigation systems from in-depth interviews with two groups of individuals: an expert group and a driver group. Data collected from N?=?1045 drivers via an online survey were analysed by structural equation modelling. The results showed that the service & display quality components of the systems were the most significant determinants of driver attitude and intention to use car navigation systems. Two other factors, namely attitude and perceived usefulness, also had impacts on driver intention. Moreover, both satisfaction and service & display quality were affected by perceived system reliability, while usefulness was affected by both perceived locational accuracy and satisfaction. Satisfaction also significantly affected perceived ease of use. In addition, we introduced new external variables to the technology acceptance model (TAM) and validated the causal connections proposed by the original TAM. The present study provides valuable insights into the core factors that significantly affect driver perspectives of and intention to use car navigation systems.     

Customers’ perceptions and intention to adopt Internet banking: the moderation effect of computer self-efficacy

In the past, the conventional concentration of Internet banking (IB) research has been on technology development, but this is now shifting to user-focused research. It has been suggested that potential users of IB services in Malaysia may not adopt the system even if they are available, due to their perceptions of this application and their level of confidence in using it to solve their banking needs. This study therefore employs the extended technology acceptance model as the theoretical framework for assessing the influences of perceived usefulness, perceived ease of use, perceived reliability, and computer self-efficacy on IB adoption in Malaysia. This study scrutinizes the moderation effect of computer self-efficacy on perceptions–intention relationships. Based on data from a sample of 133 Internet-using bank customers collected through a field survey, it was found that perceived usefulness and perceived ease of use were strong determinants of behavioral intention to adopt IB, while perceived reliability has no direct relationship with intention. Computer self-efficacy significantly moderates the relationship of perceived usefulness and perceived ease of use with intention.     

Examining the effects of information system characteristics and perceived usefulness on post adoption usage of information systems

Understanding post adoption behavior has emerged as an important issue in IS research. Organizations have invested in a plethora of Information Systems (IS) and the benefits that can be gained from these systems depend on their usage. Prior research has examined factors that impact users’ intention to continue using the IS. However, comprehending post adoption IS usage behavior has not received much attention. Building on TAM and IS success model, this study proposes that information quality and system integration influence perceived IS usefulness which will then drive post adoption usage of the IS. Post adoption IS usage is conceptualized as a broad concept that includes extended usage and exploratory usage. Data (N = 1032) was collected to test the model, in the context of a web-based student information system that students use to manage their academic work. The results show that at the post adoption stage, perceived IS usefulness is a good predictor of extended usage and exploratory usage. However, surprisingly IS usefulness was found to explain a much larger variance in exploratory usage. Information quality and system integration were found to influence IS usefulness. However, information quality also has a direct affect on extended usage, while system integration directly influenced exploratory usage. Assessment of the moderating role of gender and internet experience on model relationships reveals interesting insights. Implications are drawn for future research and practice.     

The Investigation of E-Learning System Design Quality on Usage Intention

ABSTRACT

A well-designed product increases customer value and leads to repeat usage. However, studies on the impact of website quality on customer usage fail to distinguish website competence from website capability, ignoring that website quality performance has impacts on other website quality attributes. We gather data from 314 undergraduate students and apply partial least square method to examine the design quality mechanisms and other factors that influence users’ experience. Our results indicate that offering personalized products or services is an important enabler toward enhancing users’ attitude and usage intention. Particularly, for IS education in the format of e-learning, our results suggest firms developing textbook technology platforms primarily focus on creating superior quality designs leading to capabilities that enhance user customization. The customization experience will lead to better satisfaction via both perceived usefulness and perceived ease-of-use.     

A longitudinal experimental study on the interaction effects of persuasion quality, user training, and first-hand use on user perceptions of new information technology

While prior research has investigated the main effects of external factors on user perceptions of a new IT, little work has been into the interaction effect of external factors on user perceptions. In a longitudinal experimental study, we examined the effect of the quality of persuasive argument, user training, and first-hand use on user perceptions of the new technology over time. We found that the effect of argument quality on users’ perceived ease of use was greater when users had no training. However, we did not find the same effect occurred due to perceived usefulness. We also found that first-hand use changed users’ perceived usefulness more over time when users received high quality arguments or when they had no training. While we found that first-hand use changed users’ perceived ease of use more when users received high quality arguments, first-hand use did not change users’ perceived ease of use differently whether they had or had not received prior training.     

An empirical study of the state of the practice and acceptance of model-driven engineering in four industrial cases

Model-Driven Engineering (MDE) has been promoted for many years as a means for handling the complexity of software development by raising the abstraction level and automating labor-intensive and error-prone tasks. However, there is little empirical evidence of the acceptance of MDE in industry which is the subject of this paper. The goal of this empirical study was to investigate the state of the practice of applying MDE and factors considered as important for its adoption. The subjects were developers of four large companies participating in a research project. The collected data came from multiple sources and covered the results of tool evaluations, interviews, and a survey. Among the factors, we found perceived usefulness, ease of use and the maturity of the tools to be important determinants for the adoption of MDE. We also discuss challenges with adopting MDE and present suggestions on how to succeed with the adoption process.     

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.     

An empirical analysis of the determinants of 3G adoption in China

The main aim of this study is to examine the factors that affect Chinese consumers’ intention to adopt 3G. This study has extended the Technology Acceptance Model (TAM) by incorporating the determinants of perceived usefulness, cost, trust, and demographic profiles of Chinese consumers. Data is collected from Chinese consumers via self-administered questionnaire. Structural equation modeling was applied to examine the research model proposed. Our result showed that social influence, service quality and perceived ease of use have a direct and significant relationship with perceived usefulness of 3G, and this in turn affects the consumers’ decision to adopt 3G. Contrary to existing TAM research, perceived ease of use was not found to have a direct and significant influence with Chinese consumers’ intention to adopt 3G. Our study also revealed that those with higher educational level are more likely to adopt 3G. Based on the findings, this research is able to propose several practical recommendations to 3G providers in China, such as enhancing the variety of services provided through collaborations with mobile software and content developers. Furthermore, 3G providers can focus on promoting 3G through services such as “Friends and Family” packages as Chinese consumers’ 3G adoption decisions is influenced by their social network. In terms of theoretical contributions, this study has answered many calls from past researchers to investigate the determinants of perceived usefulness. This research was also conducted in China, which is one of the largest telecommunication markets in the world.     

A review of the factors which influence the use and usefulness of information systems

The potential usefulness of different kinds of Information System (IS) for environmental management is well recognised. However, concerns have been raised about the translation of this potential into actual use and benefit to policy and planning organisations and outcomes. The aims of this paper are to identify those factors which have been found to influence the use and usefulness of IS and in doing so to provide advice for managing development and implementation processes. There is no body of empirical work on the topic for environmental application. However a substantial literature on non-environmental IS has been developed and is used as source material. A classification of IS life cycle processes is developed and the best, worst and possible predicting factors for each process identified. The best predicting factors for IS usefulness across the life cycle were found to be user participation, user perceptions and intentions, user computer experience, top management support, support and training, external pressure, IS unit professionalism and the availability of external information sources. The state of knowledge about the determinants of IS usefulness is discussed and priorities for future research are identified. The factors identified are then discussed in terms of what they mean for managing IS development and for overcoming concerns about environmental IS development and use.

The impact of IT outsourcing on information systems success

The objective of this research is to assess the impact of IT outsourcing on Information Systems’ success. We modeled the relationships among the extent of IT outsourcing, the ZOT (the Zone of Tolerance), and IS success. We justified our model using the expectancy–disconfirmation theory, the agency theory, and transaction cost economics, and we empirically tested it using structural equation modeling with responses from IS users. We found significant direct and indirect effects (through the service quality) of outsourcing on IS systems’ perceived usefulness and their users’ satisfaction. Whereas the extent of outsourcing is negatively related to the service quality and perceived usefulness, the ZOT-based IS service quality is positively related to the user satisfaction.     

Applying the Technology Acceptance Model to Social Networking Sites (SNS): Impact of Subjective Norm and Social Capital on the Acceptance of SNS

With their heavy traffic and technological capabilities, social networking sites (SNS) introduced a new means of building and maintaining perceived social capital. This study aims to identify underlying factors and causal relationships that affect behavioral intention to use SNS. For this purpose, this research developed an extended technology acceptance model, incorporating subjective norm and perceived social capital for predicting SNS acceptance and usage. Exploratory correlation and path analyses were conducted to identify the relationships between five constructs: perceived usefulness, perceived ease of use, subjective norm, perceived social capital, and intention to use. The results showed that perceived usefulness and perceived ease of use had robust effects on the user's intention to use SNS. The research findings also demonstrated that subjective norm and perceived social capital were significant predictors of both perceived usefulness and perceived ease of use and therefore should be considered as potential variables for extending the technology acceptance model.     

Using information-systems constructs to study online- and telephone-banking technologies

The research literature has seen a number of studies aimed at understanding customer attitudes towards banking technologies, and thereby providing implications for developmental planning and marketing. However, even though banking technologies have a significant amount of information systems (IS) component to them, there is a paucity of research that considers them from the IS perspective. In this paper, we fill this gap by considering three constructs, namely usefulness, ease of use and usage, that are all rooted in the IS literature. We study user’s perceptions of these constructs, as well as the relationships among them, for both online and telephone banking.     

Exploring students' awareness and perceptions: Influencing factors and individual differences driving m-learning adoption

This study investigates students' awareness and perceptions of m-learning and examines the factors affecting students' behavioral intention to adopt m-learning, by using a modified research model that integrate technology acceptance model (perceived usefulness and perceived ease of use) and unified theory of acceptance and use of technology (social influence) along with other factors (m-learning services and mobile limitations). In addition, control (gender, field of study, study level) and moderator variables (mobile capabilities, level of mobile usage, and frequent use of m-services) were introduced to verify the individual differences between respondents on the key factors affecting the adoption and usage of m-learning. Structural equations modeling and path analysis were used to test the hypotheses and the proposed model. The results revealed that perceived usefulness and perceived ease of use were found to be the primary factors driving students' intentions to use m-learning. Both m-learning services and social influence have positive effects on the acceptance of m-learning, while mobile limitations were found to be the main obstacle restraining students' participation in a m-learning environment. Most of the control variables yield no significant differences between students, but all the moderator variables were found to be significant determinants that can influence students to adopt m-learning. Overall, students have great potential to engage and integrate mobile technology into their educational environment.     

Why do individuals use computer technology? A Finnish case study

Here we discuss the motivators for computer usage in Finland. IS and non-IS researchers have reported that perceived usefulness is a major determinant in a United States workplace. This study focuses on two aspects of motivation: extrinsic and intrinsic. Perceived usefulness is an example of extrinsic motivation, whereas perceived enjoyment is intrinsic. We found that extrinsic motivation plays a greater role in individuals' behavior and that perceived ease of use affects both perceived enjoyment and usefulness, as well as usage. Moreover, they were found to mediate fully the relationship between perceived ease of use and computer usage.
