This study explores the integration of data analytics applications within Management Information Systems (MIS) and their impact on decision-making processes in organizations. The research combines qualitative and quantitative methods, drawing insights from scholarly literature, surveys, and interviews. It highlights the transformative potential of data analytics tools in facilitating informed decision-making, while also addressing challenges such as data quality. Despite these challenges, a high adoption rate of data analytics tools (78%) indicates their growing recognition in decision-making across industries. The study reports improvements in operational efficiency (35%) and competitive advantage (22%) among organizations using data analytics, validating their effectiveness in enhancing organizational performance. Future research should focus on ethical implications, longitudinal analyses, and interdisciplinary collaborations to further explore the relationship between data analytics and managerial decision-making. The research provides empirical evidence and outlines future research directions for organizations aiming to optimize decision-making through data analytics in MIS. The study emphasizes the importance of aligning technological advancements with managerial strategies to achieve informed and agile decision-making. It also underscores the need for real-time data analytics and predictive modeling to enhance decision-making processes. Ethical considerations, including data privacy and algorithmic fairness, are highlighted as critical areas for further investigation. The research concludes that data analytics applications play a pivotal role in optimizing decision-making within MIS, with significant implications for organizational performance and strategic decision-making. The findings suggest that effective data-driven decision-making can bridge the gap between data availability and actionable insights, leading to improved organizational outcomes. The study advocates for a comprehensive approach to deploying data analytics, emphasizing the importance of strategic alignment, technological readiness, and cultural transformation within organizations.This study explores the integration of data analytics applications within Management Information Systems (MIS) and their impact on decision-making processes in organizations.
