Decision Support System (DSS) - A DSS - GDSS and CSCWS: Aid in group supports complex decision-making b analyzing decisions. large amounts of data from various sources. Types of Information Systems Provide analytical tools to support decision- making. Functions: Data modeling, simulation, Financial Planning systems - financial analysis. forecasting, budgeting, and investment analysis Examples: Logistics systems, financial planning, group support systems. Spreadsheet Models - modeling, analysis, and decision-making Role: Effectiveness-oriented, supports semi- structured decisions. Executive Support System (ESS) – An ESS is a high-level system designed for senior Group Decision Support Systems (GDSS) - executives to support strategic decision brainstorming, voting, and prioritizing, allowing making. teams Support high-level strategic decisions. Computer Supported Cooperative work (CSCW) - used to share information, track Functions: Data integration, summarization, progress, and make collaborative decisions simulation. Logistics systems -used for managing and Examples: Customized executive dashboards, optimizing logistics operations enterprise-level tools. Role: Efficiency-driven, supports strategic planning and decision-making.
