Power BI consultant should focus on creating user-centric reports by customizing them based on the needs of different departments or users. Start by using themes to create a consistent visual style across all reports. Make reports interactive with slicers, drill-throughs, and filters to enhance usability. Provide detailed tooltips and hover-over explanations for clarity. Use Power BI’s bookmark and button features to create guided navigation experiences. Regularly gather feedback from users to refine the report design. Always document the customization process for future updates or iterations.
