Expert systems diffusion in British banking: Diffusion models and media factor

A study of 20 British banking organizations was carried out to test the app licability of some innovation diffusion models on the adoption of expert sy stems (ES) in industry. Secondary data, postal questionnaires, and in-depth telephone and held interviews with IT directors or leaders of knowledge-ba sed teams were used. The study determined, within this setting, that: ES di ffusion is best described by a mixed-influence model, ES adoptions are posi tively associated with media coverage in a lagged-mode, and that larger org anizations adopt ES earlier than smaller firms, but that the Pareto distrib ution was rejected.
