  • Foundation Of Information Systems In Business
  • Learning Objectives:
    • Understand the concept of a system and how it relates to information systems.
  • What Is An Information System?
    • An Information System can be any organized combination Of:
    • - people,
    • - hardware,
    • - software,
    • - communications networks,
    • - policies.
  • What Is An Information System? (continued)
    • People rely on modern information systems to communicate using a variable:
    • - physical devices (hardware).
    • - information processing instruction and
    • procedures (software).
    • - communications channels (network).
    • - stored data (data resources).
  • Examples Of Information Systems:
    • Smoke signals for communication
    • Card catalog in a library
    • The cash register
  • Real World Case: Heidelberg: Using IT To Build Smart Products And Services
    • Consider Heidelberger Druckmaschinen AG of Germany, the number one maker of high end end printing presses for printers and print media producers throughout the world. For all of its long history, the company has offered repair services to its customers.
    • Several years ago, Heidelberg developed the ability to monitor its equipment remotely using built in sensors, networking microprocessors, and other information technologies.
  • Real World Case: Heidelberg: Using IT To Build Smart Products And Services (continued)
    • Heidelberg soon found that it could provide
    • maintenance much more cost effectively with the smart
    • products.
    • Now with its machines communicating continuously
    • over the internet, relaying information about their status
    • between the print shops and Heidelberg’s regional and
    • global technical support specialists, the company has
    • the access and insight to optimize printing performance
    • in customer’s shops and minimize maintenance and
    • repair costs for Heidelberg as well as its customers.
  • Real World Case: Heidelberg: Using IT To Build Smart Products And Services (continued)
    • With such smart services, Heidelberg now offers total
    • supports of its products, which for example, can extend
    • even to the removal and resale of its machines.
    • Thus the self monitoring and networking capabilities
    • built into its products provide a strategy opportunity for
    • Heidelberg to use information technology to become a
    • partner in the successful operations of its customers,
    • while reducing its costs and creating new sources of
    • revenue from smart services.
  • Real World Case: Heidelberg: Using IT To Build Smart Products And Services (continued)
    • Questions:
    • Why should manufacturing companies build smart products and provide smart services?
    • What business benefits can be gained?
    • Provide several examples beyond discussed in this case
  • Real World Case: Heidelberg: Using IT To Build Smart Products And Services (continued)
    • Questions (continued)
    • What information technologies are used by the companies in this case to build smart products and provide smart services?
    • What are some limitations of a smart products and smart services strategies?
    • Use the internet to investigate how Heidelberg, is proceeding in its use of smart products and services.
