Project assurance personnel should support the project manager by providing an independent view on the progress and performance of the project, ensuring that it adheres to the project plan and meets its objectives without directly managing any of the project activities.References: = PRINCE2 7 Foundation handbook and online resources

Effective issue and change control within a PRINCE2 project relies heavily on a configuration management system. This system tracks all items of the project, including their versions and changes, allowing for controlled changes and ensuring that all items are identified, accounted for, and monitored throughout the project.

PRINCE2 sets minimum requirements within its themes. Themes support the principles and are aspects of project management that must be addressed continually and in parallel throughout the project. The themes provide knowledge areas necessary for the effective management of a project. References: PRINCE2 Foundation Handbook, Themes section.

The Initiating a Project process is used in PRINCE2 to ensure that there is a thorough understanding of how the project's objectives will be achieved, which includes a definition of the project's scope, benefits, risks, and approach before significant resources are committed. This process helps in establishing a clear and shared understanding of the project's basis before moving forward. References: PRINCE2 Foundation manual, PRINCE2 official resources
