What document summarizes all key project information and authorizes the project manager?

The project charter is a crucial document that serves to outline the project’s key details, including its objectives, purpose, and high-level requirements. It formally authorizes the project and grants authority to the project manager to utilize organizational resources for project activities. By defining the scope and identifying stakeholders, the project charter helps align stakeholder expectations and provides a clear direction. This early foundational document ensures that everyone involved has a shared understanding of the project goals and scope, which is essential for effective project management and execution.

In contrast, the project scope statement focuses on detailing what is included and excluded in the project, without authorizing the manager. The project management plan integrates various subsidiary plans and outlines how the project will be executed, while a project feasibility study assesses potential solutions to determine if project objectives can be achieved.
