Which is NOT one of the principles of PRINCE2?

The principle that is NOT part of PRINCE2 is one that emphasizes the importance of clearly defined roles and responsibilities in project management. PRINCE2, or PRojects IN Controlled Environments, is a structured project management methodology that focuses on the organization, control, and quality of projects.

The principles of PRINCE2 include key concepts such as managing by stages, where projects are planned and monitored in distinct phases, and managing by exception, which allows project boards to focus on critical issues while providing autonomy to project managers. Additionally, focusing on product ensures that a project is driven by the delivery of outputs that meet stakeholder requirements.

Ignoring roles and responsibilities would fundamentally undermine the effectiveness of the methodology, as clearly delineated responsibilities are essential for accountability and successful project execution. Having defined roles helps establish clear lines of authority and ensures that all team members are aware of their responsibilities, facilitating better communication and decision-making throughout the project lifecycle.
