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.
One of the first responsibilities of the executive sponsor is to select the production acceptance process owner. The process owner should be a member of the infrastructure organization since most of the ongoing activities of operating and supporting a new production application fall within this group.
