Which framework would best help to align teams toward a common goal in SAFe?

The Agile Release Train (ART) is the most suitable framework for helping to align teams toward a common goal in the Scaled Agile Framework (SAFe). The ART consists of multiple Agile teams that work together to deliver value in a coordinated manner. This alignment is achieved through synchronized iterations and a shared mission, which ensures all teams are focused on achieving the same objectives.

By operating within an ART, teams can leverage inter-team dependencies effectively, hold joint planning and review sessions, and foster collaboration across different skill sets and competencies. This integration not only enhances communication but also maximizes the chance of meeting larger program goals and delivering continuous value to the customer.

In contrast, while Scrum, Kanban, and Lean are all methodologies that have their place in Agile environments, they operate at the team level and tend to focus more on individual team effectiveness rather than cross-team alignment necessary for overarching program objectives. Thus, they may not provide the same level of structured synchronization and alignment that the Agile Release Train offers in a SAFe context.
