Which is a purpose of the 'initiating a project' process?

The primary purpose of the 'Initiating a Project' process in PRINCE2 is to provide a foundation for the project board to make an informed decision about whether it is worthwhile to proceed with the project. This process involves the development of a detailed Project Initiation Documentation that outlines the project's objectives, scope, constraints, and management strategies.
