The protagonist of my story is one of the leading retail companies in Europe, which overcame reporting chaos and took control of its data through improved governance of Power BI. Join me on a journey where I'll narrate the true success story of Power BI and Data transformation. As in any story, there's no solution without a problem. At first glance, everything seemed in place: reports, measures, dimensions, users... even fancy AI! But beneath it all lurked a storm of issues the company faced: repetitive sales reports, lack of clear visibility on key metrics, chaos from the reporting layer to the data acquisition layer. The real challenge: how can you manage thousands of reports and the corresponding labirynth of the data layers if you don't know how they are used and by whom? Here's where the real action begins! During this session, I'll present the ready-made solution to these challenges, along with the reflections and steps that led to success. I'll discuss not only the technical aspects of BI transformation, but also delve into the often overlooked human dimension: leadership and change management. I'll show how measuring PBI consumption is key when it comes to rethinking your entire data strategy and steering the BI ship away from dire straits. I'll be your guide on a real data adventure, sharing the story that starts with messy Power BI (thousands of reports, AAS S9v2 Instances), uses APIs to seamlessly navigate among thousands of users, helps you sort out the needed map to the properly setup Lakehouse, and ends in the safe haven of the governed Power BI. Finally, I will also share with you a real pirate map to the treasure trove of ROI calculations in the Power BI world.
