In PRINCE2, the Communication Management Strategy is the document that outlines how project communications should be managed. It includes how information will be disseminated amongst stakeholders and how feedback will be collected. Negative outcomes perceived by stakeholders are typically recorded as part of the feedback mechanism defined in the Communication Management Strategy. References:

The change budget in a PRINCE2 project is designed to fund changes that involve an increase in the agreed scope of the project. Such changes typically require additional budget allocations as they extend or modify what the project initially planned to deliver. References: PRINCE2 Foundation official study guide and online resources.

Decisions regarding the tailoring of the project should be recorded in the Project Initiation Documentation (PID). The PID is the key document that defines how the project is to be managed and includes specific references to any tailoring decisions made to fit the project's environment.
