This article presents a model of the wcce~s of computerbased information systems. We hypothesize that the followmg variables influence the wccess of the system: imolvement of managers III computerization projects: higher-level managerlai support: the technical quality of the system; personal factors: the attltudc of managers towards EDP personnel and the attitude of managers towards the computerized system. The research finds that the manager's attitudes to computerxatlon are related to all but the last two.
Certain classes of variables are difficult to relate to the success of the system (for example. personal factors). If the evidence for the model IS consldered strong enough to warrant action, the organization should concentrate on several key variables: high quality of the system; good management support, and good training and management involvement. The results of our research should provide better understanding of the variables associated with the ~ucccss of a computer-based system.
