CAPM Practice: Demonstrate an understanding of project roles and responsibilities

The project manager is responsible for day-to-day execution of the project, while the sponsor provides high-level guidance, secures funding, removes organizational barriers, and makes key decisions that exceed the PM's authority. This represents the fundamental distinction between tactical execution and strategic oversight.

**Why not A:** The business case is typically created by the project sponsor, not the project manager. The project manager develops the project schedule, not the sponsor. This option reverses the key responsibilities of both roles.

**Why not B:** The project manager does not make all project decisions — some decisions, particularly those involving scope, budget, and strategic direction, require sponsor approval. The sponsor's role extends well beyond approving only the final deliverable.

**Why not C:** This option incorrectly assigns team management to the sponsor. The project manager manages the project team day-to-day, while the sponsor provides strategic direction and resources at the organizational level. The PM reports to stakeholders including the sponsor.
