Information Technology Adoption Across Time: A Cross-Sectional Comparison of Pre-Adoption and Post-Adoption Beliefs
The process of information technology adoption and use is critical to deriving the benefits of information technology. Yet from a conceptual standpoint, few empirical studies have made a distinction between individuals' pre-adoption and post-adoption (continued use) beliefs and attitudes. This distinction is crucial in understanding and managing this process over time. The current study combines innovation diffusion and attitude theories in a theoretical framework to examine differences in pre-adoption and post-adoption beliefs and attitudes. The examination of Windows technology in a single organization indicates that users and potential adopters of information technology differ on their determinants of behavioral intention, attitude, and subjective norm. Potential adopter intention to adopt is solely determined by normative pressures, whereas user intention is solely determined by attitude. In addition, potential adopters base their attitude on a richer set of innovation characteristics than users. Whereas pre-adoption attitude is based on perceptions of usefulness, ease-of-use, result demonstrability, visibility, and trialability, post-adoption attitude is only based on instrumentality beliefs of usefulness and perceptions of image enhancements.
Literature Review of Information Technology Adoption Models at Firm Level
Today, information technology (IT) is universally regarded as an essential tool in enhancing the competitiveness of the economy of a country. There is consensus that IT has significant effects on the productivity of firms. These effects will only be realized if, and when, IT are widely spread and used. It is essential to understand the determinants of IT adoption. Consequently it is necessary to know the theoretical models. There are few reviews in the literature about the comparison of IT adoption models at the individual level, and to the best of our knowledge there are even fewer at the firm level. This review will fill this gap. In this study, we review theories for adoption models at the firm level used in information systems literature and discuss two prominent models: diffusion on innovation (DOI) theory, and the technology, organization, and environment (TOE) framework. The DOI found that individual characteristics, internal characteristics of organizational structure, and external characteristics of the organization are important antecedents to organizational innovativeness. The TOE framework identifies three aspects of an enterprise's context that influence the process by which it adopts and implements a technological innovation: technological context, organizational context, and environmental context. We made a thorough analysis of the TOE framework, analysing the studies that used only this theory and the studies that combine the TOE framework with other theories such as: DOI, institutional theory, and the Iacovou, Benbasat, and Dexter model. The institutional theory helps us to understand the factors that influence the adoption of interorganizational systems (IOSs); it postulates that mimetic, coercive, and normative institutional pressures existing in an institutionalized environment may influence the organization’s predisposition toward an IT-based interorganizational system. The Iacovou, Benbasat, and Dexter model, analyses IOSs characteristics that influence firms to adopt IT innovations. It is based on three contexts: perceived benefits, organizational readiness, and external pressure. The analysis of these models takes into account the empirical literature, and the difference between independent and dependent variables. The paper also makes recommendations for future research.
International Conference on Information Systems ( ICIS ) 1992 INFORMATION TECHNOLOGY DIFFUSION : A REVIEW OF EMPIRICAL RESEARCH
Innovation diffusion theory provides a useful perspective on one of the most persistently challenging topics in the IT field, namely, how to improve technology assessment, adoption and implementation. For this reason, diffusion is growing in popularity as a reference theory for empirical studies of information technology adoption and diffusion, although no comprehensive review of this body of work has been published to date. This paper presents the results of a critical review of eighteen empirical studies published during the period 1981-1991. Conclusive results were most likely when the adoption context closely matched the contexts in which classical diffusion theory was developed (for example, individual adoption of personal-use technologies), or when researchers extended diffusion theory to account for new factors specific to the IT adoption context under study. Based on classical diffusion theory and other recent conceptual work, a framework is developed to guide future research in IT diffusion. The framework maps two classes of technology (ones that conform closely to classical diffusion assumptions versus ones that do not) against locus of adoption (individual versus organizational), resulting in four IT adoption contexts. For each adoption context, variables impacting adoption and diffusion are identified. Additionally, directions for future research are discussed.
Strategic Information Systems Revisited: A Study in Sustainability and Performance
Sustainability of competitive advantage may be achieved by leveraging unique firm attributes with information technology to realize long-term performance gains. Information systems that cannot sustain competitive impact have only transient strategic value or may offer negative value if matched by a superior response by competitors. A research review of sustainability was conducted that resulted in the development of a framework depicting factors effecting sustainable competitive advantage. This study evaluate longitudinal changes in performance measures of 30 firms that have been cited as "classic" cases of strategic use of information technology. The results of this analysis indicate that not all of these classic cases can be touted as "sustained winners" Differences among strategic "sustainers" and "non-sustainers" were formally tested to determine those firm and/or industry factors that may be antecedents to sustained IT competitive advantage. Results indicate that managers must do more than simply assess the uniqueness or availability of emerging technological innovations in developing strategic IT plans. Specifically, the establishment of technological base along with substantial capital availability seem to be important prerequisites for "technologically derived" sustainability. Recognizing the need for a stronger prescriptive orientation to strategic IS, future research is outlined in an effort to develop a comprehensive framework that would link combinations of sustainability factors to actual performance.
From green to sustainability: Information Technology and an integrated sustainability framework
Sustainability has increasingly become important to business research and practice over the past decades as a result of rapid depletion of natural resources and concerns over wealth disparity and corporate social responsibility. Within this realm, the so-called triple bottom line seeks to evaluate business performance on its impacts on the environment and interested stakeholders besides profitability concerns. So far, Management Information Systems research on sustainability has been somewhat constrained in the realm of green IT, which focuses mostly on the reduction of energy consumption of corporate IT systems. Using the resource-based view as the theoretical foundation, the manuscript develops an integrated sustainability framework, illustrating the integration of human, supply chain, and IT resources to enable firms develop sustainability capabilities, which help firms deliver sustainable values to relevant stakeholders and gain sustained competitive advantage. Particularly, the role of automate, informate, transform, and infrastructure IT resources are examined in the development of sustainability capabilities. The work calls for a bold new role of IT in sustainability beyond energy consumption reduction. Implications for future research and management practice on IT and sustainability are also discussed.
Using resource-based theory to interpret the successful adoption and use of information systems and technology in manufacturing small and medium-sized enterprises
The purpose of this paper is to consider how resource-based theory can be used to explain success with the adoption and use of information systems and information technology (IS/IT) in manufacturing small and medium-sized enterprises (SMEs). A number of authors have explored the applicability of resource-based theory to the IS/IT domain, mainly at a conceptual level. Overall they infer that the key differentiators for long-term successful IS/IT deployment reside within the internal context of an organisation, based on organisational competences. This paper is based on in-depth case study research in 12 Portuguese manufacturing SMEs, which identified two factors that, from the empirical evidence, appeared to be the determinants of the different levels of success in IS/IT adoption and use. These factors were also primarily associated with the internal context of the organisations. Therefore, the findings were analysed from the perspective of resource-based theory, to understand why and how the attributes of these factors caused the differential levels of IS/IT success in the firms studied.
