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.
To gain support and cooperation for projects, a project manager must obtain a project charter that has been signed off by the projectâs sponsor. The project charter, developed in the initiating process of a project, is a formal document issued by the projectâs sponsor that authorizes the project and the project manager. A project charter dramatically reduces the risk of a project being cancelled due to lack of support or perceived value to the company.
