TL;DR: It was revealed that generic e-government applications were explored more than any specific applications, and the technology acceptance model (TAM) was the theory most often utilized to explain research models.
Abstract: After more than a decade of research in the field of e-government, it is now timely and appropriate to reflect upon the overall developmental directions in the area. The purpose of this paper is to explore research progress to date by systematically analyzing the existing body of knowledge on e-government related issues, and to reveal if there is a lack of theoretical development and rigor in the area. Usable data relating to e-government adoption research currently available were collected from 434 research articles identified from the ISI Web of Knowledge database, and by manually identifying relevant articles from journals dedicated to electronic government research such as Transforming Government: People, Process, and Policy (TGPPP), Electronic Government, an International Journal (EGIJ), and International Journal of Electronic Government Research (IJEGR). Based on our investigation of this extant literature, our findings revealed that generic e-government applications were explored more than any specific applications, and the technology acceptance model (TAM) was the theory most often utilized to explain research models. It was also revealed that

TL;DR: The empirical evidence and discussion presented in the study can help the government to improve upon and fully utilise the potential of the OPGRS as a useful tool toward a transparent and corruption free country.
Abstract: The purpose of this paper is to examine the success (by measuring intention to use and user satisfaction) of the online public grievance redressal system (OPGRS) from the perspective of the citizens of India. The success of this e-government system is examined using an integrated IS success model. The model developed includes the constructs such as system quality, information quality, service quality, perceived usefulness, perceived ease of use, perceived satisfaction, perceived risk, and behavioral intention. The proposed integrated research model of IS was validated using the response taken from 419 citizens from different cities of India. The empirical outcomes provided the positive significant connections between all 12 hypothesised relationships between eight constructs. The empirical evidence and discussion presented in the study can help the government to improve upon and fully utilise the potential of the OPGRS as a useful tool toward a transparent and corruption free country.

TL;DR: In this paper, a conceptual structural model of end-user acceptance and use of the GAIS was developed with technology acceptance model as a theoretical background and tested using a structural equation modeling with partial least squares (PLS) approach on a data collected from a survey among 112 public officers in 12 ministries in Cambodia.
Abstract: Purpose – The purpose of this paper is to investigate factors influencing end‐user acceptance and use of government administration information system (GAIS).Design/methodology/approach – A conceptual structural model of end‐user acceptance and use of the GAIS was developed with technology acceptance model as a theoretical background and tested using a structural equation modeling with partial least squares (PLS) approach on a data collected from a survey among 112 public officers in 12 ministries in Cambodia.Findings – The results indicate that the factors influencing end‐user adoption of the GAIS are significantly affected by perceived usefulness, relative advantage, and trust. Perceived usefulness of the GAIS is directly affected by subjective norm, image, output quality, and perceived ease of use.Practical implications – The results are of practical significance to all those interested in this area, mainly the government policy makers and practitioners in Cambodia's public services.Originality/value – ...

TL;DR: The findings of the study indicate that perceived usefulness, perceived ease of use, assurance of service by service provider, responsiveness of service providers, facilitating conditions, and web design (service quality) are strongly linked to intention to use EPS.
Abstract: Purpose – The purpose of this paper is to determine the factors that influence the intention to use and actual usage of a G2B system such as electronic procurement system (EPS) by various ministries in the Government of Malaysia.Design/methodology/approach – The research uses an extension of DeLone and McLean's model of IS success by including trust, facilitating conditions, and web design quality. The model is tested using an empirical approach. A questionnaire was designed and responses from 358 users from various ministries were collected and analyzed using structural equation modeling (SEM).Findings – The findings of the study indicate that: perceived usefulness, perceived ease of use, assurance of service by service providers, responsiveness of service providers, facilitating conditions, web design (service quality) are strongly linked to intention to use EPS; and intention to use is strongly linked to actual usage behavior.Practical implications – Typically, governments of developing countries spend...

TL;DR: The authors assesses the maturity of the eGovenrment (eGov) field by examining the nature of 170 papers published at three major eGov conferences using a maturity model.
Abstract: This paper assesses the maturity of the eGovenrment (eGov) field by examining the nature of 170 papers published at three major eGov conferences using a maturity model. Papers were examined mainly for rigor, but to some extent also for relevance. It was found that theory generation and theory testing are not frequent while case stories (no theory, no structured data collection) and product descriptions (no analysis or test) are. Also, claims beyond what is reasonable given the method used are frequent. As for relevance, only a few of the cases where theories are either tested or generated concern the role and nature of government, most concern general organizational issues which could well find a place within traditional IS conferences. On the positive side, global out-reach appears fairly good, as does involvement of various pertinent disciplines. It is concluded that eGov conferences need to address quality criteria, both rigor and relevance oriented ones, if the field shall develop to become a distinct research field.

TL;DR: The Unified Theory of Acceptance and Use of Technology (UTAUT) as mentioned in this paper is a unified model that integrates elements across the eight models, and empirically validate the unified model.
Abstract: Information technology (IT) acceptance research has yielded many competing models, each with different sets of acceptance determinants. In this paper, we (1) review user acceptance literature and discuss eight prominent models, (2) empirically compare the eight models and their extensions, (3) formulate a unified model that integrates elements across the eight models, and (4) empirically validate the unified model. The eight models reviewed are the theory of reasoned action, the technology acceptance model, the motivational model, the theory of planned behavior, a model combining the technology acceptance model and the theory of planned behavior, the model of PC utilization, the innovation diffusion theory, and the social cognitive theory. Using data from four organizations over a six-month period with three points of measurement, the eight models explained between 17 percent and 53 percent of the variance in user intentions to use information technology. Next, a unified model, called the Unified Theory of Acceptance and Use of Technology (UTAUT), was formulated, with four core determinants of intention and usage, and up to four moderators of key relationships. UTAUT was then tested using the original data and found to outperform the eight individual models (adjusted R2 of 69 percent). UTAUT was then confirmed with data from two new organizations with similar results (adjusted R2 of 70 percent). UTAUT thus provides a useful tool for managers needing to assess the likelihood of success for new technology introductions and helps them understand the drivers of acceptance in order to proactively design interventions (including training, marketing, etc.) targeted at populations of users that may be less inclined to adopt and use new systems. The paper also makes several recommendations for future research including developing a deeper understanding of the dynamic influences studied here, refining measurement of the core constructs used in UTAUT, and understanding the organizational outcomes associated with new technology use.

TL;DR: A large number of studies have been conducted during the last decade and a half attempting to identify those factors that contribute to information systems success, but the dependent variable in these studies-I/S success-has been an elusive one to define.
Abstract: A large number of studies have been conducted during the last decade and a half attempting to identify those factors that contribute to information systems success. However, the dependent variable in these studies-I/S success-has been an elusive one to define. Different researchers have addressed different aspects of success, making comparisons difficult and the prospect of building a cumulative tradition for I/S research similarly elusive. To organize this diverse research, as well as to present a more integrated view of the concept of I/S success, a comprehensive taxonomy is introduced. This taxonomy posits six major dimensions or categories of I/S success-SYSTEM QUALITY, INFORMATION QUALITY, USE, USER SATISFACTION, INDIVIDUAL IMPACT, and ORGANIZATIONAL IMPACT. Using these dimensions, both conceptual and empirical studies are then reviewed a total of 180 articles are cited and organized according to the dimensions of the taxonomy. Finally, the many aspects of I/S success are drawn together into a descriptive model and its implications for future I/S research are discussed.

TL;DR: This paper discusses many of the important IS success research contributions of the last decade, focusing especially on research efforts that apply, validate, challenge, and propose enhancements to the original model.
Abstract: Ten years ago, we presented the DeLone and McLean Information Systems (IS) Success Model as a framework and model for measuring the complex-dependent variable in IS research. In this paper, we discuss many of the important IS success research contributions of the last decade, focusing especially on research efforts that apply, validate, challenge, and propose enhancements to our original model. Based on our evaluation of those contributions, we propose minor refinements to the model and propose an updated DeLone and McLean IS Success Model. We discuss the utility of the updated model for measuring e-commerce system success. Finally, we make a series of recommendations regarding current and future measurement of IS success.
