Major Types of IS

After understanding the various functions of IS, let us discuss the four major types of IS used in various organizational levels in an enterprise:

Executive Support Systems (ESS): This serves the strategic level of the organization to solve critical issues such as business forecast, competitors’ information, and acquisitions. It is primarily used by senior managers to analyze aggregate internal and external data and make strategic decisions.

Decision Support Systems (DSS): This category helps managers of an organization to make decisions based on data analysis. It is used by professional and staff managers for data analysis to perform operations research, analytic modeling, and data analysis in order to make dynamic decisions.

Management Information Systems (MIS): It is a special category of IS that serves the management level of the organization. It is used by middle management to summarize transaction data and access current performance, historical records, and exception reports.

Transaction Processing Systems (TPS): It is a computerized system which executes and records several transactions required for the daily functioning of an organization. It is used by operations, personnel managers, and supervisors for daily reports, lists, and summaries of all transactions and events in business operations.
