A project charter is a foundational document for quality improvement projects, outlining the scope, objectives, and key details to align stakeholders and guide the project.

Option A (Track progress of the improvement project): Progress tracking occurs during project execution (e.g., via Gantt charts or dashboards), not the role of the charter, which defines the project’s framework.

Option B (Evaluate the productivity of the involved departments): Productivity evaluation is a performance management function, not the purpose of a project charter, which focuses on project goals.

Option C (Establish the purpose of the project): This is the correct answer. NAHQ CPHQ study materials define the project charter as a document that articulates the project’s purpose, scope, goals, team roles, and deliverables, ensuring clarity and alignment among stakeholders.

Option D (Document the project expenses): While a charter may include a budget overview, its primary objective is to define the project’s purpose and scope, not to track expenses.
