Several tasks may be grouped together and collectively added to an issue. These pre-defined Task Groups can maintain a consistent workflow in the course of resolving issues. Within Task Groups, dependencies among tasks can be established, e.g. task 3 cannot be completed until tasks 1 and 2 have been completed.
In a Task Group with Yes/No/NA scenarios, subsequent tasks may be cancelled depending on the selection of Yes, No, or NA, depending on the parameters you have defined within the Task Group.
