Computer systems that work a review of variables associated with system use

The objective of this study is to provide system developers with a framework to classify variables that influence computer use, and to assess their different roles in this respect. To that end, variables from thirty-five studies were identified, classified and reviewed for their effect on system use. Process variables including participation and involvement were the strongest predictors. Second in strength were system attributes such as perceived usefulness, and user variables such as training, skills and self-efficacy. Organizational context and support, categorized as environmental variables, and attitudes, demographics and personal traits, categorized as user variables, were the weakest predictors. The paper concludes with implications of the review for system design and implementation, and for future research.
