A group-level strategy is generated by Next-Best-Action Designer for each active group within your business structure. If a trigger is defined for all groups or issues, multiple group strategies are invoked.
These strategies filter actions by the pyIsActive property, process any All Issues and Groups functionality, and then apply the generated engagement policy filters for Eligibility, Applicability and Suitability.
There is an extension point sub-strategy for the issue and group after all filtering has occurred, named NBA_<Issue>_<Group>_Ext, where <Issue> and <Group> are the names of the issue and group respectively.
The example shown is for the Retention issue and Discount group.
