  1. Day 3 • Agenda • Wrap-up Chapter 1 • Goals • Identifying Functions of Information Systems • Identifying the Components of an IS

  2. Recall the Different Types of IS • Transaction Processing Systems (TPS) • Process Control Systems (PCS) • Enterprise Collaboration Systems (ECS) • Management Information Systems (MIS) • Decision Support Systems (DSS) • Executive Information Systems (EIS) Which ones support Management? Which ones support Operations?

  3. IS Classifications by Scope • Functional Business Systems – support basic business functions • Strategic Information Systems – support processes that provide a firm with strategic products, services, and capabilities for competitive advantage • Cross-functional Information Systems – integrated combinations of information systems Where do these fit in?TPS, PCS, ECS, MIS, DSS, EIS

  4. What is a System? Definition: A group of interrelated components, with a clearly defined boundary, working together toward a common goal by accepting inputs and producing outputs in an organized transformation process.

  5. System Components • Input – capturing and assembling elements that enter the system to be processed • Processing – transformation steps that convert input into output • Output – transferring elements that have been produced by a transformation process to their ultimate destination

  6. Cybernetic Systems Definition: a self-monitoring, self-regulating system. • Feedback – data about the performance of a system • Control – monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goal

  7. Example of a Cybernetic System

  8. A Business System

  9. IS Resources & Activities

  10. Information System Resources • People – end users and IS specialists • Hardware – physical devices and materials used in information processing including computer systems, peripherals, and media • Software – sets of information processing instructions including system software, application software and procedures • Data – facts or observations about physical phenomena or business transactions • Network – communications media and network infrastructure

  11. Lufthansa Case Goals: • Keep 3,500 highly mobile airline pilots: • Trained on the latest technology and procedures • Plugged into the corporate infrastructure • Informed about schedules, weather events, and other facts that affect their jobs • Control costs

  12. Lufthansa Case Productivity and Efficiency Improvements: • Pilots can access updated data electronically. • Pilots can work in a variety of locations including airplanes, airports, hotels, and other remote locations. • Pilots appreciate the convenience of not having to carry heavy manuals and documentation to multiple locations. • Pilots can take their required training on their laptops during downtime in any airport.

  20. Summary • There is no longer a distinction between an IT project and a business initiative. • Information systems are an important contributor to operational efficiency, employee productivity and morale, and customer service and satisfaction.
