Which of the following authorizes the project to exist within the organization?

The project charter formally authorizes the project to exist within the organization and is signed by a sponsor or senior management. It grants the project manager the authority to apply organizational resources to project activities. Without the charter, the project has no formal standing within the organization.

A project network diagram is a scheduling tool that visually represents task sequencing and dependencies, not a document that grants project authorization.

Project integration management is a PMBOK knowledge area focused on coordinating all project processes and work, not a document that authorizes the project.

Project boundaries define what is included in and excluded from the project scope, but do not serve as the formal authorization mechanism for the project.
