Introduction to PRINCE2

Correct Answer: It ensures everyone knows who is accountable for what in the project

The key benefit of clearly defined roles and responsibilities in PRINCE2 is that it ensures everyone knows who is accountable for what in the project. This clarity prevents confusion, reduces overlap or gaps in responsibilities, and establishes clear lines of accountability throughout the project organization. The second option is incorrect because PRINCE2 distributes decision-making authority across different roles based on their responsibilities and authority levels, not centralizing everything with the Project Manager. The third option contradicts PRINCE2 principles, as the methodology specifically establishes different roles with varying levels of authority appropriate to their responsibilities, rather than equal authority for all team members. The fourth option misrepresents PRINCE2's change control approach. While there is a formal structure for change management, not all changes require Project Board approval - many can be handled within defined tolerance levels by the Project Manager.

Correct Answer: Learn from Experience

The correct answer is "Learn from Experience". In PRINCE2, the principle of "Learn from Experience" emphasizes that project teams should learn from previous projects and apply those lessons to current and future projects. When a project manager reviews past project documentation before starting a new similar project, they are directly applying this principle by seeking to understand what worked well, what challenges occurred, and how to improve in the upcoming project. "Continued Business Justification" refers to ensuring that a project remains viable from a business perspective throughout its lifecycle, not about leveraging past knowledge. "Manage by Stages" is about dividing the project into manageable phases with review points between them, rather than drawing on historical project information. "Defined Roles and Responsibilities" focuses on establishing clear accountability within the project team structure, which is unrelated to reviewing past project experiences.

Correct Answer: Tailor to suit the project environment

In PRINCE2, one of the key principles is to tailor the methodology to suit the project environment. This principle recognizes that projects vary in size, complexity, importance, risk, and capability requirements. Therefore, project controls should be appropriately adapted based on these factors. The correct answer is "Tailor to suit the project environment" because this precisely describes the PRINCE2 principle that encourages adapting management controls to the specific needs of each project, rather than applying a one-size-fits-all approach. "Focus on products in all project phases" is incorrect because while PRINCE2 does emphasize product-based planning, this doesn't specifically relate to adapting controls based on project characteristics. "Establish precise organizational structures throughout the entire project lifecycle" is incorrect as it suggests rigid structures rather than tailoring approaches based on project needs. "Implement comprehensive management by exception at every project stage" is incorrect because although management by exception is a PRINCE2 principle, it doesn't address the adaptation of controls based on project characteristics.
