Why is it critical to measure the current performance before making changes to a Power BI report?

Measuring the current performance before making changes to a Power BI report is crucial because it provides a baseline understanding of how the report is functioning at the moment. This assessment allows you to identify existing strengths and weaknesses in the report, such as which visuals are performing well and which are causing delays or inefficiencies. By knowing the current performance situation, you can target specific problem areas that require improvement, rather than making changes in a vacuum without understanding their potential impact. This approach can help ensure that any modifications made will lead to better overall performance and usability of the report, thus enhancing the user experience and effectiveness in data visualization and analysis.

The importance of having a clear view of the current performance before implementing changes cannot be overstated, as it sets the stage for meaningful improvements and effective performance management in the reporting process.
