<![CDATA[Organizational effectiveness is highly dependent on how internal systems are designed to support decision-making. This study aims to analyze the influence of Management Information Systems, Total Quality Management, Reward Systems, and Performance Measurement Systems on managerial performance. Using a quantitative approach, this study conducted a survey involving 32 managers and managerial staff at PT Surya Donggala Jaya as respondents. Multiple linear regression analysis was employed using SPSS 25.0 software as the analytical tool. The results of the analysis indicate that simultaneously, Management Information Systems (MIS), Total Quality Management (TQM), Reward Systems, and Performance Measurement Systems have a positive and significant effect on improving managerial performance. However, partially, Management Information Systems and Reward Systems show a negative but insignificant effect. Likewise, the Performance Measurement System demonstrates a positive but insignificant effect. Meanwhile, Total Quality Management has a positive and significant influence on managerial performance. These findings indicate that a commitment to quality serves as the primary driver of work effectiveness. However, information systems and reward structures are not yet aligned with managerial needs, thus requiring further evaluation. The findings of this study can serve as a reference for management in reforming internal policies and ensuring that systems are not merely administrative procedures, but also instruments for enhancing human resource capacity and achieving sustainable organizational growth.]]>
