چکیده:
The purpose of this study was to combine quantitative studies on the relationship between the use of management information systems and manager's decision-making from April 1991 to the end of March 2018 in Iran. To this end, the meta-analysis method was used. The statistical population consisted of all studies done on the relationship between information systems and manager's decision-making. To select a sample, a series of criteria for the inclusion or exclusion of the studies was considered. Finally, 23 studies were selected as final sample for the inclusion in the meta-analysis. Part of the process of the meta-analysis operations was done manually and other part was done using the effect size combination method in the second version of Comprehensive Meta-Analysis software (CMA-2). Duval and Tweedie’s Trim fit test was applied to both random and fixed effects model. The Average effect size was 0.524 for the fixed model and 0.373 for the random model. Thus, according to Cohen's criteria, the effect size of the relationship between management information systems and managers’ decision-making in the random and fixed effects model is medium to high. In the end, some strategic suggestions are provided for managers.
