An Executive Support System (ESS) is a type of information system designed to help senior management make strategic decisions. It provides easy access to internal and external data, allowing executives to analyze trends and performance metrics. By presenting information in a user-friendly format, an ESS enhances decision-making efficiency. These systems often integrate data from various sources, including databases, spreadsheets, and business intelligence tools. They may also include features like dashboards and reporting tools, which help executives visualize key performance indicators (KPIs) and monitor organizational health. Overall, an ESS supports informed decision-making at the highest levels of an organization.
