Which document is critical when defining project objectives?

The project charter is the critical document when it comes to defining project objectives. It serves as a foundational text that outlines the scope, purpose, and stakeholders of a project. The charter articulates the project's goals, setting a clear direction for the work that will be undertaken. This document not only establishes the project objectives but also identifies the project's vision and the expected outcomes, ensuring that all team members and stakeholders are aligned from the start.

Additionally, the project charter can provide insight into key project constraints and assumptions, further reinforcing its role in guiding decision-making and prioritization throughout the project's lifecycle. While other documents like the risk management plan, resource allocation chart, and budget report contribute to overall project planning and execution, they do not primarily focus on defining project objectives in the same comprehensive manner as the project charter does.
