- Information System (IS): an organized method of transforming data into information that can be used for
decision making
- IS managers determine what info is needed, then they gather the data and apply the technology to convert
data into information. They also need to control the flow of info so that it goes only to those people who
need it.
- Informational quality depends on an organization’s technological resources and on the people who
manage them
- The widening role of IS results from rapid developments in electronic technologies that allow faster and
broader flows of information and communications
- Managers soon began using IS systems not merely to solve technical problems, but to analyze
management problems, especially for control purposesapplying quality-control standards to production,
comparing costs against budgeted amounts, keeping records on employee absences and turnover

- Internet: A gigantic network of networks that serves millions of computers, offers information on
business, science, government, and provides communication flows among more than 170 000 separate
networks around the world

the internet via an internet service provider (ISP) [ex. Prodigy, America Online, Earthlink]

problems spread more quickly
- Collaboration is on the rise because networked systems make it cheaper and easier to contact everyone,
whether other employees or outside organizations.
- Aided by intranets. Companies learned that complex problems can be solved better by means of
- Networking and the Virtual Company [Networkingeverything is RIGHT NOW, w/ little time to think
or train people]
