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.
Having an executive-level sponsor can be crucial for shepherding major projects, particularly those that cut across functions. But in order for this to happen, both the executive and the project leader he or she is sponsoring must be clear about their mutual expectations and time commitments for insuring a success.
