A minimum requirement for applying the change theme in PRINCE2 is to identify whether an issue has the potential to affect the continuation of the project. This involves assessing the impact of potential changes or issues on the project's objectives and deciding whether they warrant considering the project as unviable in its current form.References: = PRINCE2 7 Foundation handbook and online resources

The Project Board acts as the primary communication channel between a project and corporate or programme management. This role involves ensuring that the project aligns with corporate objectives, communicating the needs and constraints of the project to higher management, and securing necessary resources and support.

During the 'assessing issues' step, the project manager should consider the impact of alternative options for resolution. This involves evaluating different ways to address the issue, assessing their potential impacts on the project's objectives, timescales, costs, and risks, and then proposing the most appropriate solution for decision by the project board.References: = PRINCE2 7 Foundation handbook and online resources

The definition of management within the context of PRINCE2 relates to instructing the execution of tasks according to predefined, agreed-upon methods or standards. This encapsulates the directive aspects of management, ensuring tasks are completed as planned and in alignment with the project's goals and processes.References: PRINCE2 7 Foundation handbook and guide on management principles.

In PRINCE2, an 'internal' dependency refers to a relationship between two products of a project that is under the control of the project team. These dependencies are managed within the project's boundaries, unlike external dependencies which involve elements outside the project's direct control.References: PRINCE2 7 Foundation materials on product dependencies.
