2. Study of networks of hardware and software that people

9. Problem faced by command general at Persian gulf
war
The Second Marine Aircraft wing had to plan its
activities in a fast-changing political and military
environment.
The commanding general and his staff of about
110 needed large amounts of information, such as
personnel availability, logistics status, and weather
conditions and forecasts.
Getting all this information via telephones and
paper reports was a slow and possibly inaccurate
task.
10. Using RediMaster (from American
Information Systems), a local area
network, and information downloaded
from a mainframe or PCs, and EIS was
constructed that could provide the
commanders with the needed information
in seconds.
The EIS included e-mail, a calendar, word
processing, a spreadsheet, graphics
software, and anything else that could be
used to support commanders.
11. supports business or organizational decision
making activities.
DSSs serve the management, operations, and
planning levels of an organization (usually mid
and higher management) and help to make
decisions, which may be rapidly changing.
Decision support systems can be either fully
computerized, human or a combination of
both.
While academics have perceived DSS as a tool
to support decision making process, DSS used
as a tool to facilitate organizational processes.
