Which PRINCE2 principle should be followed in order to engage the business, user and supplier stakeholder interests?

The PRINCE2 principle of 'defined roles and responsibilities' ensures that the project management team structure represents the three primary stakeholder interests: business, user, and supplier. The Project Board is specifically structured to embody this, with the Executive representing the business interest, the Senior User representing the user interest, and the Senior Supplier representing the supplier interest. This structure ensures that the right people are involved in directing and managing the project, providing a clear framework for stakeholder engagement and decision-making.

B. 'Continued business justification' is the principle that ensures a project remains desirable, viable, and achievable, which is a key concern for the business stakeholder.
C. 'Learn from experience' is the principle focused on continuous improvement throughout the project lifecycle, not the structure of stakeholder engagement.
D. 'Tailor to suit the project' is the principle of adapting PRINCE2 to the specific project environment, which includes how roles are implemented, but 'A' is the core principle.
