CAPM Practice: Demonstrate an understanding of project roles and responsibilities

The project sponsor is typically responsible for approving significant changes to project budget, scope, and schedule. They provide financial resources and executive support, making strategic decisions that affect project funding and direction.

**Why not A:** The functional manager manages departmental resources and operations but does not typically have authority to approve significant budget increases on projects. Major financial decisions affecting project scope and budget fall under the project sponsor's authority.

**Why not C:** The project team executes the work but does not have the authority to approve scope changes that increase the budget by 15%. Such significant financial decisions require executive-level authorization from the sponsor or a change control board.

**Why not D:** The project manager coordinates and manages the project but typically does not have authority to approve major budget increases. The project manager would submit the change request, but the sponsor (or change control board) makes the approval decision for significant scope and budget changes.
