Select the appropriate characteristics of the executive information system in the four-level pyramid model. Characteristics of Executive Information Systems Most organizations use different types of information systems to manage their operations. The executive information system is a knowledge-based interactive system. This type of system helps managers analyze the environment in which the organization operates, identify long-term trends, and plan appropriate courses of action. The processing stage includes summarizing, simulating, and drilling down. Information comes from internal management information systems or transaction processing systems. These systems revolve around internal information flow and the final output is in the form of summary reports, graphs, or plots.
