Developers’ perceptions of object-oriented frameworks - An investigation into the impact of technological and individual characteristics

Framework-based development is currently regarded as one of the most promising software development approaches, boasting increases in lead time, productivity and quality. However, many frameworks and framework-related projects still fail, which indicates that frameworks still have unsolved problems. In this article, we will identify and investigate the major framework characteristics and individual differences that impact the most important users’ perceptions about frameworks. To test the causal relationships between these factors, we performed an online survey and analyzed the results using structural equation modeling. The results support the technology acceptance model (TAM), which was used as an underlying theory. In addition, we found that framework characteristics and individual differences have a significant impact on users’ perceptions, especially in the case of voluntary framework use. Beside TAM constructs, the results also suggest an additional determinant for the acceptance of frameworks: “confidence”. Despite the limits of our research, we foresee future research activities as well as theoretical and practical implications. Our results might be used to develop acceptable frameworks and for the evaluation of existing frameworks, their constituent parts and framework-related guidelines.     

Exploring the relationship between technology acceptance model and usability test

In the past, most studies used the technology acceptance model (TAM) to survey the subjective perception of users in using information technology. The usability test was also used to assess the ease of use of user interfaces. This study introduces a conceptual framework to explore the relationship between user’s beliefs of TAM and usability testing attributes. Usability testing was conducted on an eCampus learning system with a mobile device. TAM data was collected from the participants for analyzing a possible relationship. The findings of this study reveal that TAM results contradict the usability test results in certain areas. The focus of our proposed research model is supported from the causality between perceived ease of use and usability; however, the correlation between perceived usefulness and usability remains unclear.     

Expanding the Criteria for Evaluating Socio-Technical Software

This paper compares two evaluation criterion frameworks for sociotechnical software. Research on the technology acceptance model (TAM) confirms that perceived usefulness and perceived ease of use are relevant criteria for users evaluating organizational software. However, information technology has changed considerably since TAM's 1989 inception, so an upgraded evaluation framework may apply. The web of system performance (WOSP) model suggests eight evaluation criteria, based on a systems theory definition of performance. This paper compares WOSP and TAM criterion frameworks in a performance evaluation experiment using the analytic hierarchy process method. Subjects who used both TAM and WOSP criteria preferred the WOSP criteria, were more satisfied with its decision outcomes, and found the WOSP evaluation more accurate and complete. As sociotechnical software becomes more complex, users may need (or prefer) more comprehensive evaluation criterion frameworks.     

Factors influencing smartphone use and dependency in South Korea

This study examined the factors affecting the South Korean people’s use of smartphones within the framework of the technology acceptance model (TAM). Using an in-person survey (N = 852), the study confirmed the propositions of the TAM. The study also included individuals’ psychological antecedents, such as motivations for social inclusion and instrumental use of smartphones, innovativeness, behavioral activation system (BAS), and locus of control. While the motivations and innovativeness verified previous studies’ findings, BAS and locus of control demonstrated their unique contributions to explaining smartphone use. Smartphone dependency was also affected by the antecedents in the use of smartphones.     

Understanding age differences in PDA acceptance and performance

The present study addresses two basic determinants of technology utilization: the attitude towards a certain technology and the performance when using it. According to the technology acceptance model (TAM), perceived ease of use and usefulness are assumed to be strong determinants of the actual and successful utilization of technology. However, the relationship between the acceptance of technical devices and their successful utilization (i.e. performance) is not completely understood. In this study, users’ attitudes towards technology and their performance when interacting with a computer simulated PDA device were examined. Moreover, the moderating role of individual variables like age, gender, subjective technical confidence, and computer expertise in the relationship between technical performance and acceptance was analyzed. The results showed significant associations between performance and TAM factors. However, this interrelation was much stronger for the older group, especially between performance and the ease of use. The factors computer expertise and technical self-confidence played a minor role. Gender effects on technical self-confidence and TAM factors were identified, although they did not affect performance. Future research should focus on training formats for the older age group, which facilitate a successful interaction with technical devices.     

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.     

Effects of individuals' locus of control and computer self-efficacy on their e-learning acceptance in high-tech companies

High-tech companies encounter intense competition in today's global economy. With rapid changes in working environments, high-tech employees must learn quickly and effectively to solve difficult problems and increase their productivity. Many large high-tech companies have recently implemented electronic learning (e-learning) for employee training. However, e-learning systems are expensive and often underutilised. Therefore, understanding the factors associated with acceptance to e-learning are of priority concern. By integrating locus of control, computer self-efficacy and technology acceptance model (TAM) into one model, this study examines the feasibility of the extended TAM to explain employee acceptance of e-learning systems. Data were collected from 223 employees at five high-tech companies located in the Hsinchu Science Park, Taiwan. Analytical results indicate that locus of control had significant direct effects on perceived usefulness and perceived ease of use. Computer self-efficacy had significant direct effects on perceived ease of use and behavioural intention to use. Overall, analytical results provide strong support for using the extended TAM to explain user acceptance of e-learning systems. The research and practical implications of findings are discussed.     

Extending the technology acceptance model to explore the intention to use Second Life for enhancing healthcare education

Learners need to have good reasons to engage and accept e-learning. They need to understand that unless they do, the outcomes will be less favourable. The technology acceptance model (TAM) is the most widely recognized model addressing why users accept or reject technology. This study describes the development and evaluation of a virtual environment, the online 3D world Second Life (SL), for learning rapid sequence intubation (RSI). RSI is an increasingly frequently used method of acute airway management in healthcare settings. The intention of learners to use the system was explored based on the TAM, with the computer self-efficacy construct as an external variable. Two hundred and six nursing students participated in this study. The findings suggest that the system was perceived as useful, and that the students felt confident working with computers and intended to review RSI in SL as often as needed. However, they remained neutral regarding the ease of use of the system. Strategies were suggested for boosting the students’ self-confidence in using the system. Overall use of the TAM in this context was successful, indicating the robustness of the model. The limitations of the study were discussed and further areas of research on the TAM were proposed.     

The use and acceptance of new media entertainment technology by elderly users: development of an expanded technology acceptance model

Research on elderly people's ICT acceptance and use often relies on the technology acceptance model (TAM) framework, but has been mostly limited to task-oriented uses. This article expands approaches in technology acceptance and use by developing a model to explain entertainment-related uses of new media technology by elderly people. On a theoretical level, we expand the TAM perspective by adding concepts that act as barriers and/or facilitators of technology acceptance, namely technophobia, self-efficacy and previous experience and expertise with technology. We develop an expanded TAM by testing the role of these concepts in two studies on entertainment media technology. In Study 1, we investigate behavioural intention to use 3D cinema among N?=?125 German elderly media users (Age 50+). In Study 2, we focus the actual use of a computer game simulation by N?=?115 German and US elderly media users (Age 50+). Findings in both studies point towards the central role of perceived usefulness, here modelled as enjoyment, as the reason for elderly people's use and acceptance of entertainment media technology. Perceived ease of use is seen as a precondition for enjoyment, particularly for interactive media.     

Understanding the most influential user experiences in successful and unsuccessful technology adoptions

Understanding processes underlying technology adoption or non-adoption is an important research theme often addressed using the technology acceptance model (TAM) approach. The objective of this research was to investigate most influential user experiences in successful and unsuccessful technology adoptions using user experience related concepts and methods in conjunction with the TAM. Participants (N = 76) described their most influential user experiences related to one successful and one unsuccessful technology adoption process and evaluated both experiences using rating scales, including the central TAM related scales and user experience related scales probing emotions, psychological needs, user values, task load, and the impact of technology on the user’s well-being.The results suggested that user experience and technology acceptance related viewpoints can complement each other in order to gain a more holistic understanding of the factors affecting the success or failure of technology adoptions, and the results showed how these variables typically behave in both contexts. The overall valence of user experience was significantly affected by perceived usefulness, the fulfillment of psychological needs, and the salience of negative emotions in the most influential user experiences of successful adoptions, and by perceived usefulness, output quality, and the salience of negative emotions in the unsuccessful adoptions.     

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.     

A confidence-based framework for business to consumer (B2C) mobile commerce adoption

The Technology Acceptance Model (TAM) has been considered to be fundamental in determining the acceptance of new technology in the past decades. The two beliefs, ease of use and usefulness, in the model may not, however, fully explain the consumers’ behavior in an emerging environment, such as mobile commerce (m-commerce). This paper aims to develop a framework for m-commerce adoption in consumer decision-making processes. In this paper TAM has been adopted and extended to analyze successful m-commerce adoption. The key elements of the proposed confidence-based framework for B2C m-commerce adoption include psychological and behavioral factors. Psychological factors include history-based confidence, institution-based confidence and personality-based confidence. Behavioral factors include perceived ease of use and perceived usefulness of the mobile application and technology.     

Continuance intention of E-portfolio system: A confirmatory and multigroup invariance analysis of technology acceptance model

The technology acceptance model (TAM) has been applied in various fields to study a wide range of information technologies. Although TAM has been developed in this research stream in Taiwan, TAM's issues of measurement have received scant attention. A robust model must perform measurement invariance across different respondent subgroups to ensure that various sample profiles have the same relationship. A survey of regarding E-portfolio system reuse intention was constructed, resulting in 360 valid responses across subgroups differing in gender, grade, and levels of willingness to share, to examine the measurement invariance of TAM. The results empirically support the validity of our TAM instrument for evaluating E-portfolio reuse intentions behavior. These findings suggest that men and women, differing grades, levels of willingness to share conceptualize the TAM construct in similarly. The implications of these results enable us to understand TAM's validity in E-portfolio acceptance research.     

User acceptance of wireless technology in organizations: A comparison of alternative models

This paper compared two versions of technology acceptance model (TAM) in understanding the determinants of user intention to use wireless technology in the workplace. The first model is derived from original TAM that includes perceived usefulness, perceived ease of use, attitude and behavioral intention, while the alternative model is a parsimonious version in which the attitude was taken out. The results indicated that TAM, either original or parsimonious, is successful in explaining user intention to use wireless technology in organizations. In addition, the parsimonious model showed a better model fit than that of the original model.     

The effect of computer self-efficacy on enterprise resource planning usage

Global competition has impelled numerous organisations to employ enterprise resource planning (ERP) systems, although quite frequently without success. Studies have demonstrated that a major factor for failure is employee resistance in organisations using these systems. Exactly the factors that facilitate ERP adoption among users have seldom been identified. This study examines the usage behaviour of a sample of users of the new technology of ERP system using a technology acceptance model (TAM). Furthermore, this paper incorporates an additional behavioural construct, computer self-efficacy (CSE), to improve the predictive value of the original TAM model, named revised TAM. Additionally, the structural equation model (SEM) is used to verify the causal relationships between variables. Analytical results confirm that not only is the TAM appropriate for explaining the use of ERP, but that incorporating CSE enhances the power of the model.     

Online Banking Information Systems Acceptance: An Empirical Examination of System Characteristics and Web Security

Prior work on the technology acceptance model (TAM) is mainly devoted to the influence of TAM’s core motivational factors and their impact on behavioral intent toward IS acceptance. Relatively little research has focused on what specific system design characteristics motivate individuals toward IS acceptance. This article identified specific systems design factors and examined their impact on TAM’s motivational factors through the TAM. The findings will help designers to design and implement better user-accepted systems.

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.     

Exploring Koreans’ smartphone usage: An integrated model of the technology acceptance model and uses and gratifications theory

This study investigates factors that influence adoption and use of smartphones among Koreans and seeks to integrate two theoretical approaches: the technology acceptance model (TAM) and the uses and gratifications (U&G) approach. To that end, the study used data from a self-reported survey of 491 Korean adults who use Apple’s iPhone. A structural equation model employed in the current study demonstrates that Koreans’ smartphone use is affected more by motivations based on instrumental and goal-oriented use than by ritualized and less-goal oriented use. The findings suggest that to spread information system with innovative and active features, developers should pay attention to users’ intrinsic motivations as well as to their extrinsic perceptions.
