Abstract

A study was conducted to examine the effect of implementing a new system on its users, specifically, the relationship between pre-implementation expectations and their perceived benefits based on post-implementation experience. Disconfirmation theory was used as the theoretical basis; this predicts that unrealistically high expectations will result in lower levels of perceived benefit than those associated with realistic expectations (i.e. where expectations match experience). Support was found for this prediction, refuting the predictions of dissonance theory. In addition to examining expectations of ...

Abstract

This paper investigates the Impact of IT investments and worker composition on the productivity of life insurance companies. The majority of prev~ous IT productivity studies follow a technological imperative, hypothesizing a direct relationship between higher IT investments and increased productivity. This paper shifts the focus toward the organizational imperative, which views returns on IT investments as a result of the alignment between technology and other critical management choices. Specifically, the study focuses on the alignment between IT investments and worker composition, measured in terms of relative numbers of clerical, managerial, and professional positions to ...

Abstract

Empirical research has revealed differences in the economic impact of information technology (IT) across industries. However, the source of these differences is unclear. In this study we analyze the role of the competitive environment in moderating the productive impact of information technology and regular capital. We focus on two important features of an industry's competitive environment: industry concentration and industry dynamism. Industry concentration is the degree to which the output of an entire industry is produced by a few firms and is considered an inverse ...

Abstract

An interview was used to determine, whether flow experiences as defined by Csikszentmihalyi would occur in information technology use. Results indicate, that flow experience is quite frequent while performing a variety of tasks ranging from word processing to programming to visual design and information search on a desktop computer. Also flow experiences seem to occur while using a range of software matching the variety of tasks mentioned above. Participants named factors they thought were causing flow experiences while using information technology. ...

Abstract

The emerging mobile commerce (m-commerce) technology promises exciting possibilities for marketplace exchanges, but expected benefits to consumers as well as businesses await an understanding of consumer acceptance of this technology. Borrowing the technology acceptance model (TAM) from the work environment, we apply it to the consumer context (c-TAM) and extend it by incorporating both utilitarian and hedonic aspects of technology use. In workplace settings, perceived usefulness has been the predominant driver of technology adoption. Our empirical results show that while perceived ...

Abstract

This paper reports the views of 80 senior IT managers about IT evaluation approaches, and the benefits that IT provides for their organizations. Their views were obtained through a survey mailed to medium to large organizations in both Europe and the US. The survey sought answers to three questions: How does the senior IT manager's organization assess the value of its (1) overall IT investment portfolio? (2) individual IT projects and applications? (3) IT function? Questions for the survey were based ...

Abstract

This paper proposes a conceptual framework of three maturity levels for the effective management of end users during systems development. The framework is based on a model that explains all the important elements involved during the establishment and maintenance of sound relationships between the different role players in a software project team. It is argued that the level of end user maturity is determined by the experience and knowledge of the end user regarding the nature of a given project. As ...

Abstract

Users and IT personnel typically belong to different organizational units with different objectives and values. This often creates a perceived boundary between the two units, reducing the degree to which users accept the installation of new IT. Much IT research suggests that increased user involvement and influence on IT development can overcome user - IT personnel differences and thereby increase user acceptance. However, the realization of this objective can be problematic when implementing new IT in large organizations within which such ...

Abstract

Organizations increasingly evaluate information technology in terms of its impact on the individual and his/her work. Academics have shown increased attention to developing measures of technology success in terms of impact on work. One of these efforts produced an instrument that measures how extensively information technology applications impact task productivity, task innovation, customer satisfaction, and management control. These constructs reflect perceived usefulness of information technology application for work. This paper reports on confirmatory analysis and factorial invariance tests of the impact ...
