Interaction with real world problems

Decision support systems need to be designed with the goal of interacting with real world problems. The only purpose of these decision support systems is to produce information that assists real humans in making real decisions in the real world, a task that would inherently involve collecting, organising, analysing, and processing data that originates from reality instead of fabrication or imagination. Decision support systems that are used only to solve imaginary problems will be of highly limited use in the real world, because they would not be able respond to any realistic stimuli and subsequently would not be able to produce any meaningful solutions to these real world situations.

Improvements to decisions

Decision support systems should be able to improve decisions, not make them worse. The purpose of any information system, as defined by the Preliminary HSC information processes and technology course, is to assist the end user. The end user of a decision support system is the human being whom the decision support system is helping to make decisions. As such, if the decision support system is unable to improve decisions, or indeed, if it is only capable of making decisions worse, it is has failed to assist the end user and hence is completely redundant.
