What is the primary purpose of the Outline Business Case (OBC)?

The primary purpose of the Outline Business Case (OBC) is to identify the 'preferred option' that optimizes value for money. The OBC serves as a pivotal document in project management that establishes the viability of a project by assessing different options and determining which one aligns best with the overall objectives and stakeholder needs. This analysis is crucial for making informed decisions about how resources will be allocated and ensuring that investment leads to the desired outcomes.

By focusing on the preferred option, the OBC facilitates a comprehensive evaluation of potential paths forward, considering factors such as feasibility, value for money, and strategic alignment. This process helps ensure that the selected option not only meets project requirements but also delivers the maximum benefit to the organization and its stakeholders.

The other choices, while important aspects of project management, do not capture the primary aim of the OBC. For instance, while commercial arrangements and payment mechanisms are critical in the later stages of project development, the OBC's focus lies in selecting the most advantageous overall approach before delving into specific financial details.
