The difference between a project sponsor and a project manager is that Sponsors own the why and the value. Project managers own the how and the delivery discipline. When these roles are confused, projects stall, decisions drift, and accountability weakens.

The owner of the project is not the project manager, the PMO, or a committee. It is the individual accountable for ensuring the project delivers its intended business value. In large organizations, clear project ownership is foundational to governance, delivery discipline, and strategic alignment.
