During PI Planning, which essential aspect must be aligned among all teams?

During PI Planning, the alignment of program and team objectives is vital because it ensures that all teams are working towards a common goal. The convergence of these objectives allows for coordination across teams, fostering collaboration and facilitating the delivery of value in alignment with the ART (Agile Release Train) goals.

By establishing shared objectives, teams can identify interdependencies, align their work, and understand how their contributions fit into the larger program vision. This shared understanding is crucial for successful execution during the program increment, as it helps teams prioritize their backlogs and work collaboratively to achieve the overarching goals.

The other options focus on different aspects that may be important in project management but do not encapsulate the core focus of PI Planning, which is to align all teams around the program's vision and objectives.
