Microsoft Office) Management Information Systems - Produces reports summarized from transaction data, usually in one functional area (ex. report on total sales for each cust.) Decision Support System - Provides access to data and analysis tools (ex. a “what-if: analysis of changes in budget) Expert System - Mimics human experts in a particular area and makes a decision (ex. credit cart approval analysis) Executive dashboard - Presents structured, summarized information about aspects of business important to executives (ex. report showing status of sales by product) Supply Chain Management System - Manages flows of products, services and information among organizations (Wal-Mart Retail Link System, connecting suppliers) Electronic Commerce System - Enables transactions among organizations and between organizations and customers (www.dell.com) 2.2 COMPETITIVE ADVANTAGE AND STRATEGIC SYSTEMS - Competitive strategy is statement that identifies a business’s strategies to compete, its goals and plans and policies that
