Executive sponsor. Executive sponsor (sometimes called project sponsor or senior responsible owner) is a role in project management, usually the senior member of the project board and often the chair. The project sponsor will be a senior executive in a corporation (often at or just below board level) who is responsible to the business for the success of the project.
Just as important as knowing what project sponsorship is, however, is knowing what project sponsorship is not. First and foremost, project sponsorship is not an invitation to participate in creating project deliverables; make daily, routine decisions; or create project timelines and schedules.
