Abstract Whether increased usage of computer-based information systems (CBIS) results in improved end-user satisfaction is investigated. Data collected from 98 end users in 12 organizations indicate that as an aggregate both the frequency of on-the-job CBIS use and the proportion of total time spent using CBIS on the job are positively correlated with end-user satisfaction. For upper level managers, the higher the frequency of computer use per week, the more satisfied they are with their information systems. However, for lower level managers, it is not the frequency but the amount of time spent using computers that correlates significantly with their satisfaction level. This information in conjunction with the nature of the information systems (monitor, exception, inquiry, and analysis) that an organization provides to its users, could be pivotal in designing improved measures of end-user satisfaction.
