The following are the properties possesses by DSS:
(i) Ability to adapt to changing needs: Semi-structured and unstructured decisions often don‘t conform to a predefined set of decision-making rules. Because of this, their decision support systems must provide for enough flexibility to enable users to model their own information needs. They should also be capable of adopting to changing information needs.
(ii) Flexibility: Flexibility in a DSS is of paramount importance: Information requests mode to a DSS will often be relatively unsystematic and distinct. Manager can make many requests without being sure where the search for information will lead him. He often needs a variety of tools to satisfy such requests. The output from a DSS may also be used to prepare customised output to be examined by other people.
(iii) Ease of learning & use: Since DSS is often built and operated by users rather than by computer professionals, the tools that accompany them should be relatively easy to learn & use. Such software tools employ user-oriented interfaces such as grids, graphics, non- procedural 4GL, natural English. These interfaces make it easier for user to conceptualize and perform the decision-making process.
