Which of the following should the project charter include?

A risk register is a detailed document that identifies and analyzes specific project risks, which is developed later in the planning process, not as part of the initial, high-level project charter.

The project charter is created early in the project lifecycle and serves to formally authorize the project, providing a high-level overview including the project purpose, measurable objectives, high-level requirements, and typically a brief project description that defines what the project is about. It empowers the project manager with authority to apply organizational resources to project activities.

A post-mortem analysis (or lessons learned) is performed at the end of a project or phase, not included in the initial project charter.

An issues log is used to track and manage issues that arise during project execution, which is an operational document created after the project charter.
