Management Information Systems
The data that supports an organization's decision-making process has to be stored and maintained in the management information system (MIS). The MIS is not just one system but a collection of systems designed to support various organizational functions. This article explores the different types of MIS systems and the level of decision-making each supports. Focus on the Transaction Process Systems diagram and note how the various information systems (pink boxes) inform decisions at different levels in the organization.
Executive Information Systems
Although similar to a DSS, an executive information system (EIS) is customized for an individual executive. These systems provide specific information for strategic decisions. For example, a CEO's EIS may include special spreadsheets that present financial data comparing the company to its principal competitors and graphs showing current economic and industry trends.
