An Information System (IS) is comprised of
all the components that collect, manipulate,
and disseminate data or information. It
usually includes hardware, software, people,
communications systems, and the data itself.
In business, MIS directors play four major
roles:
The functional support role of managing
and processing data and generating reports.
The decision support role that allows
users to ask “What if . . . ?” questions and
find the answers using analytical tools.
The strategic support role that strengthen
a company’s competitive positioning in the
market.
The performance monitoring role that helps
to establish relevant and measurable
objectives, monitor performances and alert
on deviations between them.
Management Information Systems (MIS) is the
system that collects and processes data
(information) and provides it to managers at
all levels who use it for decision making,
planning, program implementation, and
control.
