The Performance Monitor provides a summary of completion rates for each Country, Area, Location and Account. The Performance Monitor is based on the content that is assigned into various Fuel Gauges.
Each account group has it's own default view that is limited to the country, area or location that they are assigned to, but those managers who oversee more than one level (Area Managers for example) can "drill down" by clicking the Fuel Gauge they are interested in.
For an overview of Performance Monitor please take a look at the following video.
