The ART planning board is a key tool used during PI Planning in the Scaled Agile Framework (SAFe). It is utilized to visualize and communicate the critical aspects of the Program Increment (PI) planning process. According to the SAFe documentation, the ART planning board highlights the new feature delivery dates, feature dependencies among teams, and relevant milestones1. This visualization aids in the coordination and alignment of the teams within the Agile Release Train (ART).

The correct answer is B. Dependencies between teams, as the ART planning board specifically communicates the dependencies that exist between different teams working on the ART. This is crucial for ensuring that teams are aware of and can manage the interdependencies effectively, which is essential for the smooth delivery of value through the ART.

The other options, such as ART PI risks (A), team velocity ©, and PI Objectives (D), are important elements within the SAFe framework but are not the primary focus of the ART planning board. The board’s main purpose is to provide visibility into how the teams’ work interrelates and to facilitate the management of cross-team dependencies to ensure that the ART can achieve its objectives efficiently and effectively.
