Power BI : les 6 pièges à éviter absolument (édition débutant)

In this video, I share the most common mistakes I see in Power BI projects, especially among those who are no longer complete beginners… but not yet experts either. It’s often at this stage that bad habits take root: poorly structured models, misuse of Power Query or DAX, slow reports, cluttered dashboards, lack of documentation… and ultimately, projects that are harder to maintain, less reliable, and less useful for users. The goal here is simple: to help you take a step back and examine how you build your reports to avoid the most frequent pitfalls and progress with a better methodology. 🎁 Go from Beginner to Pro on Power BI: https://www.datacoach.ca/register/pbi... 🔗 Discover all our services: http://datacoach.ca/ 📥 Download Power BI Desktop (free): https://www.microsoft.com/fr-fr/downl... ⏱️ Chapters 00:00 Introduction 00:37 Mistake #1: Using Power BI like Excel 01:54 Mistake #2: Creating a dashboard to impress instead of solving a real need 03:42 Mistake #3: Neglecting project documentation 05:35 Free training on Power BI Intro 05:57 Mistake #4: Poorly distributing calculations between Power Query, DAX, and calculated columns 07:36 Mistake #5: Ignoring performance issues 09:18 Mistake #6: Overloading the dashboard with too much information 10:42 Conclusion 📩 Tell me in the comments which error you see most often in Power BI projects. 🔔 Subscribe so you don't miss anything: a new video every week!
