This research explores the factors influencing the effectiveness of Management Information Systems (MIS) through the integration of Operating Systems (OS) and Servers. The study aims to understand how this integration impacts business effectiveness, particularly in planning, control, and data storage. The research employs a qualitative approach, involving in-depth interviews with IT leaders, system administrators, and staff from various companies that have implemented OS and Server integration. The findings reveal that successful integration enhances operational efficiency, improves data access speed, and supports more informed business decisions. However, challenges such as technical obstacles, cultural changes, and policy adjustments are significant. The study also highlights the importance of a holistic and sustainable approach to integration, tailored to the specific business context and industry characteristics. The research concludes that understanding and addressing these challenges can maximize the benefits of OS and Server integration, leading to improved business performance and competitiveness.This research explores the factors influencing the effectiveness of Management Information Systems (MIS) through the integration of Operating Systems (OS) and Servers.
