Imran Burki brings us an introduction to Power BI Goals:
One of the things I love about Power BI (and Microsoft in general) is that they empower everyone in the organization to utilize their software – Power BI Goals are so easy to set up. There’s absolutely no special skillset required. You just need a Power BI Premium or Premium Per User license. Power BI Goals essentially enable you to keep track of key performance indicators in a single, unified view. Goals, and the actuals, are data driven. Goals can also be hardcoded. The data for actuals and goals must reside in a report that you can access.
