Characteristics of a DSS:
A DSS enables its users to solve a particular problem using the ‘what-if' analysis. Using this analysis, one can make modifications to the data related to the problem and find out the effect of these changes on the results. Thus, a DSS is used for analyzing the various possibilities and deriving an appropriate strategy for each situation. Following are the characteristics of a DSS:
- They are computerized information systems that are interactive in nature. These systems can be used by decision makers in order to control the order of operations performed.
- DSSs provides support to those decision making activities or processes that are specific in nature. They facilitate support to the decision makers in the organization, but do not replace them.
- They can be independent systems or subsystems of a more integrated and larger information system. DSSs as independent systems can collect or reproduce data from other information systems.
- DSSs enhance the accuracy, quality, relevance, and the overall effectiveness of a specific decision or a set of related decisions. They can also be used repeatedly.
- A DSS is flexible so that it supports semi-structured and unstructured information. This is an essential attribute of DSSs since decisions are always based on assumptions.
- Decision making may require a lot of information. For meaningful information to be made available to decision makers, it is necessary to store the information in databases from which data can be accessed easily and quickly.
