The principle of 'Ensure continued business justification' in PRINCE2 requires that the project remains justified throughout its lifecycle. By reviewing the benefits management approach to ensure it includes sufficient benefit reviews after the project's closure, the project board is applying this principle to confirm that the project continues to provide value and that its benefits are realized as planned, even post-project.References: = PRINCE2 7 Foundation Training Manual and official PRINCE2 website documentation

Quality control events, such as testing, should be documented in the 'Quality Management Approach' according to PRINCE2 guidelines. This document outlines how quality will be managed throughout the project, detailing specific methods and events, including schedules for quality assurance activities and testing, to ensure that products meet their defined quality criteria.
