A communication-driven DSS supports more than one
person working on a shared task;
A data-driven DSS emphasizes access to and
manipulation of internal company data and,
sometimes, external data.
A document-driven DSS manages, retrieves, and
manipulates unstructured information in a variety of
electronic formats.
A knowledge-driven DSS provides
specialized problem-solving expertise stored as
facts, rules, procedures, or in similar structures.
A model-driven DSSemphasizes access to and
manipulation of a statistical, financial, optimization,
or simulation model
DSS
 Non-routine
decisions
MIS
 Routine decisions
◦ Monthly
◦ Weekly
◦ Daily
◦ Often unique
problems


Requires data +
human
knowledge/wisdom
Subjective
◦ Best choice is very
unclear



Operational
Easy to automate
Often the best
choice is obvious
DSS
 Analyze specific
problems
MIS
 Performance info
◦ More feedback driven
◦ How are we doing?
DSS
 Interactive Reports

Flexible, adaptive
reports
MIS
 Periodic Reports

Pre-specified, fixed
reports
DSS
 Analytical modeling
+ Knowledge base
MIS
 Processing of data
