The Improvement Target Control is located at the top left of the Report Screen.
In Ipiphany your Improvement Target acts as your goal, it tells Ipiphany what you are trying to achieve. Set this first so that Ipiphany can provide you with correctly targeted insights.
To set an Improvement Target simply:
Click on the control
Choose an attribute
Choose a function to apply to that attribute
The control will automatically close and create a metric that is a combination of the selected attribute and function
By default only score or numeric attributes are displayed. To select a categorical attribute click 'Show Categorical Attributes'.
If you would like to reduce the value of your selected attribute (Call Time for example) then set 'I want to Minimize this'
