A project brief is a document that outlines all of the project's major components. The project brief is a technique of presenting this information concisely that outlines the project's goals, scope, primary deliverables, milestones, and timetable.

The project manager creates the project brief. However, a project manager does not provide the material in the project brief. Instead, clients and project stakeholders are the ones responsible for outlining the what, who, when, and why of a project.
