Our current (and preferred) organization has teams from the same Jira project spread across multiple Agile Release Trains. We have organize based on value stream and cross functionality to ensure autonomous trains.
For example:
Platform A/Jira Project A has one team on ART 1, one team on ART 2, and one team on ART3
Platform B/Jira Project B has one team on ART 1, one team on ART 2, and one team on ART3
Is it truly not possible to build programs in Jira Align using one Jira project across multiple platforms? Is there no way to integrate at the team level and not the project level?
