CAPM Practice: Demonstrate an understanding of project roles and responsibilities

The project manager is responsible for the day-to-day management and execution of the project, while the project sponsor provides executive-level support, funding authorization, and helps remove organizational obstacles that are beyond the project manager's authority.

**Why not A:** The project manager does not define the business case — that is typically developed by the sponsor or business analyst to justify the investment. The sponsor's role extends well beyond managing stakeholder communications; they provide strategic support, funding, and remove organizational barriers.

**Why not B:** The project manager does not secure funding — funding authorization is the sponsor's responsibility. The sponsor does not manage the day-to-day budget — that is the project manager's responsibility. This option reverses core financial responsibilities of both roles.

**Why not C:** The project manager does not approve all deliverables — the sponsor or customer typically provides formal acceptance. The sponsor does not handle resource allocation at the task level — that is the project manager's responsibility during planning and execution.
