Information Systems Lecture 2 MD. Ahsan – Ul - Hasan Information Systems Functions Five Functions of Information Systems: Information Processing and Usability Function Educating and Learning Function Information systems development Function Management and Control Function Strategy and Planning Function Contemporary approaches to Information Systems Technical Approach: The technical approach to information systems emphasizes mathematically based models to study information systems, as well as the physical and formal capabilities of these systems.
