Solution Trains (ST)
ARTs can be grouped into ST (Solution-Trains). A ST is needed if you want to create a PI Planning session which spawns multiple ARTs (to also visualize cross-ART dependencies).
Create a Solution Train
Navigate to the the Organization (1) menu and select the “Solution Trains“ (2) tab. Then hit the “Create Solution Train“ button on the top right create a new ST.
Set the name of the ST
Add one or more ARTs to the ST
An ART can only be in one Solution Train at once
