Abstract. Electronic government, or e‐government, increases the convenience and accessibility of government services and information to citizens. Despite the benefits of e‐government – increased government accountability to citizens, greater public access to information and a more efficient, cost‐effective government – the success and acceptance of e‐government initiatives, such as online voting and licence renewal, are contingent upon citizens’ willingness to adopt this innovation. In order to develop ‘citizen‐centred’ e‐government services that provide participants with accessible, relevant information and quality services that are more expedient than traditional ‘brick and mortar’ transactions, government agencies must first understand the factors that influence citizen adoption of this innovation. This study integrates constructs from the Technology Acceptance Model, Diffusions of Innovation theory and web trust models to form a parsimonious yet comprehensive model of factors that influence citizen adoption of e‐government initiatives. The study was conducted by surveying a broad diversity of citizens at a community event. The findings indicate that perceived ease of use, compatibility and trustworthiness are significant predictors of citizens’ intention to use an e‐government service. Implications of this study for research and practice are presented.

Phân tích phương trình cấu trúc dựa trên phương pháp bình phương tối thiểu phần (PLS‐SEM) được sử dụng rộng rãi trong lĩnh vực hệ thống thông tin, cũng như trong nhiều lĩnh vực khác nơi mà các phương pháp thống kê đa biến được áp dụng. Một trong những vấn đề cơ bản nhất trong PLS‐SEM là ước lượng kích thước mẫu tối thiểu. Quy tắc '10 lần' đã trở thành lựa chọn phổ biến nhờ vào tính đơn giản khi áp dụng, mặc dù nó thường dẫn đến việc ước lượng không chính xác. Chúng tôi đề xuất hai phương pháp liên quan, dựa trên các phương trình toán học, như là những lựa chọn thay thế cho việc ước lượng kích thước mẫu tối thiểu trong PLS‐SEM: phương pháp căn bậc hai ngược, và phương pháp gamma-exponential. Dựa trên ba thí nghiệm Monte Carlo, chúng tôi chứng minh rằng cả hai phương pháp đều khá chính xác. Phương pháp căn bậc hai ngược đặc biệt thu hút nhờ vào tính đơn giản khi áp dụng. © 2016 John Wiley & Sons Ltd

Mobile banking is an emerging application of mobile commerce that could become an additional revenue source to both banks and telecom service providers. It is a form of service convergence enabled by innovative technologies. Despite the alleged benefits of mobile banking, its acceptance has been short of industry expectations. One plausible explanation may be consumers' initial lack of trust in available services. The objective of our research is to reveal the mechanisms associated with the initial formation of people's trust in mobile banking and intention to use the service. For this, we attempt to understand the effect of four antecedent variables (structural assurances, relative benefits, personal propensity to trust and firm reputation) on shaping a person's initial trust in mobile banking and its usage intention. They represent four types of trust‐inducing forces: institutional offering (structural assurances), cognition (perceived benefits), personality (personal propensity) and firm characteristics (firm reputation). We examine individual significance of the selected antecedents and also their comparative reliability in explaining the two exogenous variables. The technical basis of our empirical research is the innovative mobile banking solution that uses cellphones with a built‐in smart chipset. The survey data are analyzed using structural equation modelling. The analysis showed that three variables (relative benefits, propensity to trust and structural assurances) had a significant effect on initial trust in mobile banking. Also, the perception of initial trust and relative benefits was vital in promoting personal intention to make use of related services. However, contrary to our expectation, the reputation as a firm characteristics variable failed to attract people to mobile banking.

Technostress—defined as stress that individuals experience due to their use of Information Systems—represents an emerging phenomenon of scholarly investigation. It examines how and why the use of IS causes individuals to experience various demands that they find stressful. This paper develops a framework for guiding future research in technostress experienced by individuals in organizations. We first review and critically analyse the state of current research on technostress reported in journals from the IS discipline and the non‐IS disciplines that study stress in organizations (eg, organizational behaviour and psychological stress). We then develop our framework in the form of the “technostress trifecta”—techno‐eustress, techno‐distress, and Information Systems design principles for technostress. The paper challenges 3 key ideas imbued in the existing technostress literature. First, it develops the argument that, in contrast to negative outcomes, technostress can lead topositive outcomes such as greater effectiveness and innovationat work. Second, it suggests that instead of limiting the role of IS to that of being a stress creator in the technostress phenomenon, it should beexpanded to that of enhancing the positive and mitigating the negative effects of technostressthrough appropriate design. Third, it lays the groundwork for guiding future research in technostress through aninterdisciplinary framing that enriches both the IS and the psychological stress literaturesthrough a potential discourse of disciplinary exchange.

This paper argues that it is of crucial importance that information systems (IS) research and practice associates technology innovation with the context within which it is embedded. It identifies three principles to be followed in order to address the contextual processes involved in IS implementation: first, technology innovation should be considered in relation to socio‐organizational change; second, analysis should consider not only the local organizational, but also the national and international context; and third, analysis should consider both the technical/rational decisions and actions involved in the innovation process and the cultural, social and cognitive forces of such a process. These principles are demonstrated with the analysis of a case study of organizational reform in Cyprus.

This paper describes empirical research into agile requirements engineering (RE) practices. Based on an analysis of data collected in 16 US software development organizations, we identify six agile practices. We also identify seven challenges that are created by the use of these practices. We further analyse how this collection of practices helps mitigate some, while exacerbating other risks in RE. We provide a framework for evaluating the impact and appropriateness of agile RE practices by relating them to RE risks. Two risks that are intractable by agile RE practices emerge from the analysis. First, problems with customer inability and a lack of concurrence among customers significantly impact agile development. Second, risks associated with the neglecting non‐functional requirements such as security and scalability are a serious concern. Developers should carefully evaluate the risk factors in their project environment to understand whether the benefits of agile RE practices outweigh the costs imposed by the challenges.

Abstract. The original ‘stages of growth’ model, as applied to the field of Information Systems (Gibson & Nolan, 1974), may be viewed as seminal, given the influence it has had on both theory and practice (Nolan, 1984; Sullivan, 1985; Ward, et al., 1990). This is so, despite the model's lack of substantiation based on empirical evidence, the overly simplistic assumptions on which it is based, and the limited focus of the original concept (Benbasat, et al., 1984; King & Kraemer, 1984).

Since its first appearance, the model has been refined following many applications (Nolan, 1979, 1984). In addition, others have developed ‘stages of growth’ models of their own. For example, Somogyi & Galliers, (1987a, b)provide a model depicting the move from basic data processing systems to strategic information systems, tracing the early days of commercial applications of computing through to the present day (Ward et al. 1990). Earl (1983, 1986, 1988, 1989) proposes a stages‐model for information systems planning, as does Bhabuta (1988), while Hirschheim, et al. (1988) have developed a more broadly focused model associated with the development of the information‐systems management function.

As a result of a review of the above and of a case study research undertaken in Perth, Western Australia, a revised model was developed, which takes account of current thinking and past experience in the application of the various ‘stages of growth’ models (Sutherland & Galliers, 1989).

This paper sets out to review some of these models and proceeds to describe the process of developing, testing and applying the revised ‘stages of growth’ model. The model is more broadly focused than the original concept, incorporating strategic, organizational, human resource and management considerations. As a result, it is argued that this model has greater utility than its predecessors.

Abstract.  This paper identifies factors that affected over 200 information system (IS) process innovation adoption decisions in three organizational environments over a period that spanned four decades. The analysis is based on Rogers's (1995) theory of Diffusion of Innovations (DOI). The results show that several DOI factors strongly affect IS process innovation adoption. These include user need recognition, availability of technological infrastructure, past experience, own trials, autonomous work, ease of use, learning by doing and standards. Yet, a large number of IS process innovation adoptions followed no discernible pattern.

Abstract. In an increasingly dynamic business environment characterized by fast cycle times, shifting markets and unstable technology, a business organization’s survival hinges on its ability to align IT capabilities with business goals. To facilitate the successful introduction of new IT applications, issues of project risk must be addressed, and the expectations of multiple stakeholders must be managed appropriately. To the extent that users and developers may harbour different perceptions regarding project risk, areas of conflict may arise. By understanding the differences in how users and project managers perceive the risks, insights can be gained that may help to ensure the successful delivery of systems. Prior research has focused on the project manager’s perspective of IT project risk. This paper explores the issue of IT project risk from the user perspective and compares it with risk perceptions of project managers. A Delphi study reveals that these two stakeholder groups have different perceptions of risk factors. Through comparison with a previous study on project manager risk perceptions, zones of concordance and discordance that must be reconciled are identified.

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.
