Management Support Systems (MSS) are computer-based tools that help managers make informed decisions. They provide relevant data, analysis, and reporting features to support planning, monitoring, and controlling organizational activities. By integrating information from various sources, MSS enhances the decision-making process and improves overall efficiency. These systems can include various types of software, such as Decision Support Systems (DSS), Executive Information Systems (EIS), and Group Decision Support Systems (GDSS). Each type serves a specific purpose, from analyzing complex data to facilitating collaboration among team members, ultimately aiding in strategic management and operational effectiveness.
