Which system offers strategic managers access to a broad range of information?

The Executive Information System (EIS) is specifically designed to provide strategic managers with access to a wide array of aggregated data from various sources. This system is tailored for high-level decision-making, allowing managers to analyze trends and evaluate the performance of the organization by presenting information in a format that is easy to understand, often featuring dashboards and summary reports.

An EIS typically pulls data from different internal systems, including Management Information Systems (MIS) and Transaction Processing Systems (TPS), and can also integrate external data. This broad perspective is crucial for strategic planning and forecasting, enabling executives to make informed decisions that align with the organization's long-term goals.

Other systems, like the Transaction Processing System, focus more on day-to-day transaction handling and operational activities, while the Management Information System provides reports and summaries based on internal data, but lacks the broader strategic focus. The Operational Control System, on the other hand, deals with managing and controlling daily operations and is not designed for high-level strategic decision-making. Therefore, the EIS stands out as the most appropriate choice for the context of providing strategic managers with comprehensive information.
