What I Did:

Data Collection and Preparation: I started by collecting sales data from various sources and then spent some time cleaning and transforming it. This ensured I was working with reliable information right from the start.

Data Modeling and DAX Usage: I built a comprehensive data model that ties everything together. To extract deeper insights, I utilized DAX formulas like CALCULATE and FILTER. These formulas helped me perform dynamic calculations under different scenarios and truly understand the performance trends.

Visualization and Dashboard Design: Using Power BI, I created an interactive, user-friendly dashboard. This tool visually presents sales trends, regional distributions, and key performance metrics in a clear and engaging way. Along the journey, I also leveraged some Excel techniques for data prep to ensure everything was in tip-top shape.

Impact on Business Processes: Beyond just crunching numbers, this report is all about how data-driven decision making can transform business processes. It’s a practical demonstration of how using the right tools and methods can lead to smarter, more informed strategies.
