Which is a minimum requirement for applying the plans theme?

A minimum requirement for applying the Plans theme in PRINCE2® is that team managers in the project must prepare team plans. This ensures that each part of the project controlled by a team manager is adequately planned in line with the overall project plan and stage plans. These team plans provide detailed guidance on how products will be delivered within the constraints set by the project management.References: PRINCE2® 7 Foundation resources and study materials.
