In PRINCE2, baselines are used to establish a reference point for the agreed state of products, against which actual progress can be compared and managed. By requesting a report to check for conflicts between the agreed and actual states of products, the project manager is effectively applying the concept of baselines within issue management. This helps in identifying deviations from the agreed deliverables and initiating corrective actions to address these discrepancies.References: (PRINCE2 7 Foundation Handbook, AXELOS)

Time-driven controls in PRINCE2 are specifically designed to monitor the progress of Work Packages and management stages at regular intervals. These controls ensure that the project stays on schedule and that any deviations are identified and managed promptly. References: PRINCE2 Foundation official study materials.

The use of product descriptions supports the 'focus on products' principle by documenting the quality expectations set by the customer or stakeholders. These descriptions ensure that everyone involved understands what needs to be delivered and to what standards, thereby aligning project outputs with stakeholder needs and expectations.
