An information technology executive is a senior-level professional who supervises computerized information systems at an organization. Depending upon the size of the company, this individual may be focused on management and strategic planning, as is the case for vice-presidents and directors. At other organizations, he could be more heavily involved in on-site applications and troubleshooting, which is in line with the job duties of an information technology manager or supervisor.

Decision support systems (DSS) are interactive software-based systems intended to help managers in decision-making by accessing large volumes of information generated from various related information systems involved in organizational business processes, such as office automation system, transaction processing system, etc. DSS uses the summary information, exceptions, patterns, and trends using the analytical models. A decision support system helps in decision-making but does not necessarily give a decision itself.
