In building Power BI dashboards for operational or sales performance, I start by clearly defining the objectives and understanding the needs of the stakeholders who will be using the dashboard. For projects like AtliQ Mart and regional car sales performance, I focused on key metrics such as sales growth, revenue, customer satisfaction, and product performance. I ensured these metrics were aligned with the business goals. I used visualizations like line charts for trend analysis, bar charts for comparing sales across regions or products, and pie charts for market share distribution. The emphasis was on creating dashboards that were not only visually appealing but also easy to interpret, ensuring that the data could be quickly understood and acted upon. Additionally, I incorporated interactive elements to allow users to drill down into specific data points for deeper insights.
