What Is An Information System?
An Information System can be any organized combination Of:
- people,
- hardware,
- software,
- communications networks,
- policies.
4
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).
5
Examples Of Information Systems:

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.
7
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
