Select the Rank option to select a PI from the trend group associated with your estimate. With this method, PIs are grouped into “bins” ranging from much lower to much higher than average.
Once you have selected a PI rank value, resting your
cursor over the value will display a hover tip showing the PI value associated
with your chosen PI rank, project size, and trend group:
Be aware that PI rank values calculated from trend lines will change when the trend group or project size are changed.
