What are the differences between structured, unstructured, and semistructured decisions?
|
:The procedures to follow when decision is needed can be specified in advance
:It is not possible to specify in advance most of the decision procedures to follow :Decision procedures can be pre-specified, but not enough to lead to the correct decision |

|
How is DSS different than MIS?
|
DSS: ad hoc, quick response, analytical models, specialized databases
MIS: Produces everyday decision making, reports, display, & responses |
