A PRINCE2 project is midway through its delivery stage when the Project Manager realizes that the Business Case has not been reviewed since the project was authorized. The project board is concerned that the project may no longer be viable, but no one has been assigned to check the ongoing justification. Which PRINCE2 principle is being violated?
This principle requires that a project has a justifiable Business Case and that the justification is reviewed and updated throughout the project, not just at the start. Since the Business Case has not been reviewed since authorization, the project no longer fulfills this principle. The project board must ensure the Business Case remains valid at every stage.
Why this answer
The Continued business justification principle demands that a PRINCE2 project has a valid Business Case and that it is reviewed and updated at every stage and at each exception. Because the Business Case has not been reviewed since authorization, the project is running without confirmed justification, which directly violates this principle. The other principles address different aspects of project management.
Exam trap
The trap here is assuming that the Business Case only needs to be created once during Starting up a Project and then forgotten.
