摘要：This paper develops a model of the growth of information systems expenditures in the United States. The model incorporates two major factors that influence the rate and pattern of spending growth-the diffusion of technological innovation and the effect of price on the demand for computing. Traditional studies have focused on the role of innovation while ignoring the effects of price on the growth process. We show that while information systems expenses initially grew following an S-curve, more...

摘要：A theoretical framework is developed in which alternative mechanisms of allocating congestion-prone computer resources are studied and compared. Two-discrete and continuum-models of economies are presented to depict a small and a large economy respectively. Alternative allocation mechanisms are discussed in these two models: (1) the private bargaining approach, (2) allocations attainable through Nash equilibria and (3) the Clarke-Groves tax mechanism in the discrete economy model, and (4) Mend...

摘要：The Decision Support Systems (DSS) literature is in general agreement that use of DSS leads to individual and organizational change, but there is no consensus as to whether DSS and their designers serve as agents for directed or nondirected change. Researchers have proceeded from two different sets of premises, drawing different conclusions about the nature of DSS. This paper considers both views, examining how differences in designers' attitudes toward change agency ought to be manifest in th...

摘要：The concept of decision support systems that emerged in the seventies offered the promise of computer-based tools that would enable decision makers to develop better and more creative solutions to the problems they face. The realization of this promise depends on the validity of two assumptions: (1) individuals can be helped to be more creative and (2) software, appropriately designed, can provide this help. Evidence from creativity research supports the first assumption. This paper explores t...

摘要：User involvement is recommended to analysts as a technique of successful system development, but as a process it is little understood. This case study compares four process models of user involvement learning, conflict, political and garbage-can with each other and with an empirical example of system development. Different models are seen as appropriate to explaining the nature of user involvement in different stages of development and contexts. Structural conditions and issues of power are sh...
