Which of the following is a key responsibility of the project sponsor?
The sponsor sits above the project manager in authority, so they secure funding, staff and facilities, and escalate issues the team cannot resolve. This directly satisfies the stem's requirement for a key sponsor responsibility: providing resources and clearing obstacles that block delivery.
Why this answer
The project sponsor provides resources, champions the project, and resolves escalations. The PM plans and executes; the team does tasks; the steering committee provides governance.
