Final answer:
An EIS produces periodic, exception, and demand reports to support decision-making at the executive level.
Step-by-step explanation:
An EIS (Executive Information System) is a computer-based system that provides managerial information to support decision-making at the executive level. It primarily produces periodic reports, which are generated on a regular basis, such as daily, weekly, or monthly. These reports summarize key performance indicators, financial data, sales figures, and other relevant information.
However, an EIS can also generate exception reports. These reports are triggered when certain predefined criteria or thresholds are met. For example, an exception report might be generated if sales decline by more than 10% compared to the previous month.
An EIS can also generate demand reports, which are ad-hoc reports requested by executives to obtain specific information for decision-making. These reports are not generated on a regular basis and are tailored to meet the specific information needs of the executives.
