How should a Data Analyst update an existing dashboard to include a new data source with budget data?

The most effective way to incorporate a new data source into an existing dashboard is by editing the current workbook to connect to the new data source. This approach allows the analyst to maintain the existing visualizations, calculations, filters, and interactivity of the dashboard while seamlessly adding the new budget data. Once the connection to the new data source is established, the analyst can integrate the relevant data fields into the existing visualizations or create new ones as necessary.

Building a new dashboard from scratch or replacing the current dashboard altogether would mean losing the work already done and could lead to unnecessary duplication of effort. Using data blending can be beneficial in certain scenarios, particularly when working with disparate data sources that need to be combined for analysis. However, in this case, directly editing the existing workbook is a more straightforward and efficient method when straightforward integration into an existing dashboard is the goal.
