What is the primary function of a project charter?

The primary function of a project charter is to authorize a project and outline its objectives. The project charter serves as a formal document that signals the commencement of a project, providing the necessary permissions and authority for the project manager and team to begin work. It establishes the project's purpose, goals, and key stakeholders, giving everyone involved a clear understanding of what the project aims to achieve and the foundational reasons for its existence.

Additionally, the project charter communicates important information about the project's scope, constraints, and assumptions, serving as a reference point throughout the project's lifecycle. By setting the stage for effective leadership and decision-making, the project charter helps ensure that all parties are aligned and moving forward toward common objectives.
