2.5.1 The characteristics of decision support systems
Decision support systems have a number of characteristics that allow them to be effective management support tools. It has to be appreciated that all DSSs work, in principle, in the same way. Some, however, are small in scope and offer only some of the following features (Stair & Reynold 2001)::
- Handle large amount of data from different sources.
- Provide report and presentation facility.
- Offer both textual and graphical orientation.
- Support optimization, satisficing and heuristic approaches.
