The Benefits Management Approach in PRINCE2 is designed to outline how and when the improvements (benefits) delivered by the project will be measured and to define the reason for delivering these improvements. This approach ensures that there is a clear understanding of the project's intended outcomes and how these will contribute to the organization's objectives, thereby justifying the project's existence and ongoing investment.References: PRINCE2 Foundation Manual

The purpose of the Closing a Project process is to ensure that the objectives defined in the Project Initiation Documentation (PID) have been achieved. This process involves verifying that the project's deliverables meet the objectives and that the project has fulfilled its purposes as planned.

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.

Tolerances are a minimum requirement for applying the 'progress' theme in PRINCE2. They define the allowable deviations in time, cost, quality, scope, risk, and benefit objectives that do not require escalation to higher management levels. This control mechanism ensures that the project operates within agreed boundaries without frequent upper management intervention.References: = PRINCE27 Foundation handbook and online resources

A minimum requirement for applying the Organization Theme in PRINCE2 is to document the project management team structure. This documentation includes defining the roles and responsibilities of each team member, facilitating clear communication and effective management throughout the project lifecycle.
