An information system involves these five components.
Information Systems Manager
An Information Systems (IS) manager looks at the “big picture” of
a company's computer systems. As you discover in this chapter, an
information system consists of people, procedures, software, hard-
ware, and data. The IS manager is the person who brings them all
together to get results. An IS manager might oversee an initiative
to satisfy an information need, such as for production managers
to receive daily reports. This initiative might include assembling a
team of programmers, identifying the required hardware and soft-
ware, developing procedures for handling the information request,
and delivering the data to the managers in an easy-to-use format.

puter as well as the external devices that interact with it, such as printers,
cables, and monitors.
