In the Scaled Agile Framework (SAFe®), Agile Teams work together as part of an Agile Release Train (ART). One of the defining features that unites all teams within an ART is synchronization to a common cadence. This means all teams follow the same iteration schedule—planning, executing, reviewing, and retrospecting in harmony.
The common cadence provides a steady rhythm that simplifies coordination and dependency management across multiple teams. It ensures alignment by creating predictable, synchronized events such as PI Planning, System Demos, and Inspect & Adapt workshops. This synchronization allows cross-team integration and transparency, enabling teams to deliver coherent system-level increments and support scaled agility.
From SAFe guidance:
“Teams on the Agile Release Train (ART) align to a common cadence and synchronize their iterations, which facilitates system-level integration and provides regular opportunities for assessment and adaptation.”
Therefore, the correct answer is D. Synchronization to a common cadence, as it represents the key organizing attribute shared by all teams on an ART.
