During the PI Planning event, when are planning adjustments agreed upon?

During the PI Planning event, planning adjustments are agreed upon during the management review and problem-solving meeting, which is the last activity of the first day of the event1. In this meeting, the management team reviews the draft plans of the teams, identifies and resolves any issues, risks, or dependencies, and makes any necessary changes to the scope, people, or resources1. The management team also communicates the planning adjustments back to the Agile Release Train (ART) the next day, before the teams continue their planning and make the appropriate adjustments2. References: PI Planning, Management Review and Problem-Solving
