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.
* A project sponsor, at a level that is appropriate to funding the project, authorizes the project by approving a project charter. Projects are usually chartered and authorized external to the project. * On some projects, the sponsor may also be part of the project team. As sponsors have a major share in the projectâs success, and therefore, at times, may take an active role on the project team. * For issues that are beyond the control of the project manager, the sponsor serves as an escalation path.
