Power BI dashboards can be customized by tailoring visuals, metrics, and layouts to suit specific users' needs. For instance, executives might need a high-level view of KPIs, while analysts require more detailed data. Power BI allows dashboards to be filtered by role or department, showing only relevant data. Personalizable features, such as drill-throughs, filters, and pinned visuals, enable users to interact with the dashboard in ways that best serve their tasks. Consultants can create different views or versions for various teams, ensuring that everyone gets the data most relevant to their role.
