PRINCE2 recommends three levels of planning (Project Plan, Stage Plan, Team Plan) to reflect the needs of different levels of management involved in a project. Each plan serves a specific management purpose and addresses the needs of different management levels within the project. References: PRINCE2 Foundation official documentation and study materials.

The purpose of the Managing Product Delivery process is to ensure that there is a controlled link between the Project Manager and the Team Managers. This link facilitates the proper execution and delivery of Work Packages, ensuring that work is carried out effectively, monitored, and controlled.
