Which theme ensures that the project remains viable?

The theme that ensures the project remains viable is the Business Case. This theme is crucial as it provides a clear justification for the project by outlining the benefits, costs, and risks involved. The Business Case is not just a one-time document; it is continuously assessed and updated throughout the life of the project to ensure that the rationale for the project remains valid. This involves evaluating whether the anticipated benefits are still achievable and if they outweigh the costs and risks.

By maintaining a focus on the Business Case, project managers and stakeholders are able to make informed decisions regarding the project's direction, ensuring that it aligns with organizational goals and that it remains a worthwhile investment. If the Business Case becomes unviable—for instance, if costs exceed predicted benefits or if changes in organizational priorities occur—the project can be reevaluated or even terminated to prevent wasting resources.

In contrast, other themes, while important in their own rights, do not directly address the overall viability of the project. Progress focuses on tracking and managing the project's advancement, Risk deals with identifying and mitigating uncertainties, and Organization outlines the project team structure and clarification of roles. While all themes contribute to project success, the Business Case specifically keeps the project's purpose and value at the forefront, ensuring ongoing viability.
