Definitions of : DSS
According to Gerrity : DSS as an effective
blend of human intelligence , information
technology , and software which interact closely
to solve complex problems.
DSS is an interactive computer based system
which facilitates the solution of unstructured
Initial risk analysis (management science).
Model examination using experience, judgment, and
Initial model mathematically correct, but incomplete.
DSS provided very quick analysis.
DSS: flexible and responsive. Allows managerial
intuition and judgment.
Consistent and objective decisions.
Objective of DSSIdentify information processing as the foundation
of managerial work.
Identify which media are more suitable for
supporting managerial work

Elements of DSSDSS tools.
DSS tools are pograms or codes which are foundations
used to create the DSS generators and in turn specific
The combination of DSS tools in the computer
hardware is know as DSS generators.
DSS generators turn into specific DSS.
Components of DSS programsDialogue management.
Users of DSSThe use of DSS is not limited to middle and upper
level management or chief executives. They are the
main user. They bring with them differing
needs, and differing levels of sophistication. The
DSS designer need to specific decision–making
attributes in to consideration so that it is possible
for the user to interact successfully with the DSS.
Capabilities of DSS Can update or manipulate the database and select
data from database.
Create special reports in a desired format.
Perform calculations and execute aggregation of
Produce report, memos, letters, and resume from
information available in the database.
Perform financial analysis.
Limitations of DSSDue to its small memories and limited storage
capacities, DSS has definite computational
It is slow, compared to the speed of large
Most DSS are designed for individual but they
can be designed so that several computers can be
liked for limited information sharing.
