We use meta-analytic structural equation modeling (MASEM) to examine how organizational planning leads to managerial performance. Specifically, we test a theoretically-driven model of how participative budgeting and strategic performance measurement systems can positively impact managerial job performance through role clarity. Our analyses of 60 studies (containing 99 effect sizes) from multidisciplinary literature indicate role clarity mediates the relationship between planning implementation processes and managerial job performance. Additionally, and contrary to previous research, path analysis suggests job-relevant information mediates the relationship between role clarity and managerial job performance. We explain how participation in planning may prompt managers who are clear about their roles to seek additional information in order to perform well. Finally, we identify a need in future research for a greater diversity of the operationalizations of the constructs, levels of analysis, and data collection methods
