| Summary: | The purpose of this research has been to make a contribution to knowledge about those processes and phenomena which influence the use of computer-based decision systems by senior managers for their own decision activities. In the course of the thesis, research questions are addressed which relate to the nature of the role of the directly-accessed computer in the working life of the top manager, and especially to the factors which influence computer adoption and use. A review of relevant literature enabled gaps in existing knowledge about senior managerial computer use to be identified, and indicated the potential value of exploratory research. A programme of interviews was devised and executed which enabled the exploration of the research problem across a sample of senior managers from private and public organizations. It is felt that the methodology of performing intra- and inter-organizational comparisons among computer-exposed managers was fundamental to achieving new insights into managerial behaviours. Following qualitative and qualitative analysis of the research data, a dynamic behavioural model of the computer adoption process in large organizations is proposed together with a description of salient behavioural features at key points in the process. This theoretical model contributes to an understanding of the nature and circumstances of the senior managerial behaviours associated with direct computer use.
