CAPM Practice: Demonstrate an understanding of project roles and responsibilities

The project manager's primary distinguishing responsibility is managing the day-to-day execution of the project, including coordinating team members, tracking progress, and addressing issues. While sponsors may be involved in some project decisions, the PM owns the daily operational management.

**Why not A:** Securing organizational funding and resources is a project sponsor responsibility, not the project manager's distinguishing role. The PM's defining responsibility is managing the day-to-day execution, coordination, and tracking of project work.

**Why not C:** Providing strategic direction and business justification is the sponsor's domain. The project manager operates at a tactical level, translating strategic direction into actionable plans and coordinating daily execution, not setting the project's strategic course.

**Why not D:** Approving major deliverables and scope changes is typically a sponsor or change control board responsibility. While the PM recommends and facilitates these decisions, the distinguishing PM responsibility is the daily operational management of the project.
