Power BI – Power Pivot – Creating your first data model and KPI.
While PowerPivot isn't necessarily “new technology,” businesses are trying to move towards it due to how Excel savvy end users can create their own reports without tying up IT resources. KPI's are just another addition to PowerPivot that allows users to visually analyze data across millions of rows.
A KPI (Key Performance Indicator) is a graphical representation that displays progress against a predefined measure or business goal. KPIs make it easier for end users to evaluate the amount of progress without reading a bunch of data.
