It aggregates data from various sources, allowing decision-makers to monitor performance, identify trends, and gain actionable insights in real-time. Dashboards facilitate quick understanding by presenting complex data in a clear, organized manner, enabling businesses to respond swiftly to changes in the market. Ultimately, they support informed decision-making and enhance operational efficiency.
