The CSSBB source defines a project charter as a written document that defines the team’s mission, scope, objectives, time frames, and consequences. It also states that identifying these details in written form provides a constant and consistent target for the team .

While option D is not stated word-for-word in the source, it is the closest interpretation of the charter’s function as a consistent target and expectation-setting document. Therefore, the verified best answer is D .
