The change of structural, perception and attitudinal dimensions in information technology implementation processes

This paper provides an empirical assessment of the impact of Information Technology (IT) implementation, as a learning process, on the people who use computers or the products of computers in the performance of their daily activities. In particular, this study examines the changes in those people’s perception of structural dimensions (the level of centralization and formalization), their perception of IT attributes (belief compatibility, work compatibility, relative advantage, complexity, and observability), and their attitudes toward IT (attitude toward change, and computer related anxiety). This study examines both direct changes produced by these constructs and their indirect changes through IT usage, user satisfaction, and user performance as mediating variables. The results show that small changes occurred between the paired constructs of centralization, formalization, belief and attitude. Meanwhile, the path coefficients of observability, complexity, and anxiety indicate that they have experienced changes of medium size; and the path coefficients of compatibility and relative advantage indicate that large changes occurred. Most of the relationships recorded are due to the direct effects of the initial measures while the indirect effects through usage, satisfaction, and performance show only small influences.
