A program board is a visual summary of the features or goals, when they need to be reached, and any cross-team dependencies impacting their delivery. The program board helps teams within the Agile Release Train (ART) to coordinate their work and communicate their plan to the entire organization. One of the main purposes of the program board is to help teams identify and manage dependencies between teams, which can affect the delivery of value and increase the risk of delays or failures. By visualizing and tracking dependencies on the program board, teams can avoid or resolve them during the Program Increment (PI) planning event or throughout the PI execution. References: SAFe Program Board 101: Everything You Need To Know, SAFe Program Board: Good Practices for SAFe PI Planning, Tips for using a SAFe program board
