Why we use DSS

To check that everything is okay.
-- A variance report which actually performs the action that the data is
okay or not with comparison to other system
To confirm the obvious
-- Sometime user hesitate to take decision due to lack of supportive
document. DSS strengthen the decision by providing knowledge based
information with that.
To figure out how something works......
--Sometime customer A pays more than customer B but pays late than B. So
identifying the key customer DSS helps.
To convey information in a more digestable manner
--DSS provides graphical representation of data after analysing it. So the
data can be available in "at-a-glance" manner.
To identify the "Out-of-Ordinary"
--Ranking system of DSS achieve this goal.
To grab a grain from a granary
--To the point, correct and effective data is the key of DSS
To provide a Report of Record
--Sometime we have all the analysis but lost in the heap. DSS places the
document in structured manner so user can have the proper document in time
of need.
To confirm and sometime discover Trends and Relationship
--DSS provides the information about the flows of resources. By comparing
the sales over time it propose the trend to follow.
To forecast and What-if analysis
--DSS set the benchmark and set the alarm. The system inform you before
