The correct answer is B . PRINCE2 7 is designed to be tailored to the organizational environment in which a project operates. It specifies the purpose and required governance of the business case rather than requiring every organization to use identical terminology or documentation structures.

The City Council already has a mature and standardized procedure. Its strategic business case provides the early justification during starting up a project, and the more detailed business case is then developed during initiating a project. Functionally, this follows the PRINCE2 lifecycle in which an initial justification is established early and subsequently refined into a sufficiently detailed business case for project authorization and ongoing decision-making.

Option C treats the label “outline business case” as mandatory. PRINCE2 tailoring allows established corporate terminology and management products to be used where they fulfil the required purpose and preserve the necessary controls. Option A refers to multiple analytical perspectives but does not address the central issue in the scenario: whether the Council’s established business-case procedure may legitimately be used. Option D is incorrect because the existence of a portfolio office does not transfer all project-level responsibility for developing and maintaining the project’s business justification away from the project organization.

The key consideration is equivalence of purpose and control, not rigid terminology.

PRINCE2 7 reference topics: Business case practice; tailoring; organizational standards; starting up a project; initiating a project; continued business justification.
