Step-by-step explanation:
A decision support system is a type of information system that incorporates human software interactions in complex automated systems, especially in the decision-making processes of workers as they are supported by the software system. When a decision support system 'goes live,' it requires better-skilled workers, better teamwork, redesigned processes, and new decision rights to be in place. These systems are often used in group IT, personal IT, and enterprise IT.
