easy-to-use interface, and allows for the
decision maker's own insights." For Little
(1970), a DSS is a "model-based set of
procedures for processing data and judgments
to assist a manager in his decision-making."

2. History of DSS
According to Keen and Scott Morton (1978),
the concept of decision support has evolved
from two main areas of research: theoretical
studies of organizational decision making done
during the late 1950s and early 1960s, and

concept of DSS became an area of research of

In the middle and late 1980s, executive
information systems (EIS), group decision
support systems (GDSS), and organizational
decision support systems (ODSS) evolved
from the single user and model-oriented DSS.
