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.
Project sponsors typically are members of senior management who carry a respectable level of influence and authority and serve as proponents of projects. Project sponsors often are called by different names, such as product sponsor, project director, account manager or business unit manager. Some projects do not have clearly defined project sponsors. Even more common are projects that have sponsors, but the sponsorsâ duties are not defined and documented. If a project has no apparent sponsor or a weak sponsor, the project will suffer a severe handicap whenever senior management support must be obtained. As a project manager, if your project does not have a project sponsor, you can work to cultivate that role with a likely senior manager. If your project has a designated project sponsor, but the duties are vague, it is in both your and the projectâs best interest to define and document a proposed set of duties and negotiate them with the sponsor.
