Deep dives
Challenges with Data Modeling
One of the main challenges with Power BI is the assumed knowledge of data modeling. Users need to have a clear understanding of relational databases and how to structure their data models to get accurate results in their reports. Many users struggle with joining tables, creating relationships, and designing an optimized data model.
Importance of Clear Data Analysis Questions
Another challenge in using Power BI is the need for clear data analysis questions. Without having a specific question or objective in mind, users may end up with confusion rather than clear results from the application. It is crucial to have a clear understanding of what data is needed and what insights are being sought in order to effectively use Power BI.
Cloud Confusion and Windows-only Desktop App
Power BI's transition to the cloud and being a Windows-only desktop app can be another source of difficulty for users. The shift to the cloud can be confusing for those accustomed to working with local files, and there may be challenges in understanding how to share and collaborate on reports and dashboards. Additionally, the fact that Power BI is currently limited to Windows can pose limitations for Mac or Linux users who are not able to access the full functionality of the tool.
The Importance of Clear Analytical Goals
Having clear analytical goals is crucial for effective data analysis. Without a clear question or goal in mind, it becomes challenging to find actionable insights regardless of the data analysis tool being used. Whether it's Power BI, Tableau, or any other tool, the absence of analytical goals hinders the ability to generate meaningful and actionable reports. It is important to define specific questions and goals before starting the analysis process.
Importance of Presentation Design and Visualization Choices
Presentation design and choosing the right visualizations are crucial components of effective data communication. It is both an art and a science to select the most appropriate visualization type that best represents the data and answers the specific analytical questions. Visual aspects such as colors, layouts, and graph design play a significant role in conveying insights effectively. While tools like Power BI provide a range of visualization options, it is essential for data practitioners to possess a good understanding of visualization concepts and best practices to create visually appealing and informative reports.
Mike, Seth, & Tommy talk through a conversation from Tim Warner, a Content Developer at Microsoft.
The crux of the argument revolves around the amount of Assumed Knowledge that is needed to start with Power BI (data modeling, knowledge, etc) before even jumping in.
We have been working in Power BI for a LONG time, so it is difficult to remember the early days, but how many new developers are dealing with these same issues now?
