What is the purpose of the Business Case theme in PRINCE2?

The Business Case theme in PRINCE2 plays a crucial role in ensuring that the project remains aligned with the overall business objectives. Its primary purpose is to document the rationale for undertaking a project, highlighting the expected benefits, costs, risks, and timeframes. This thematic focus aids in justifying the project's initiation and ongoing funding by clearly linking it to strategic goals and organizational value.

Having a well-defined Business Case encourages regular reviews as the project progresses, ensuring that the project still aligns with changing business needs and priorities. This continual alignment is essential for decision-making, as it helps stakeholders assess whether the project should continue, be adjusted, or be halted if the anticipated benefits are no longer viable.

In contrast, other options, such as creating budgets, outlining expenditures, or enforcing quality control measures, do not capture the central purpose of the Business Case theme, which is specifically to validate and underpin the strategic alignment of the project with the organization's goals.
