Which of the following MUST be clearly defined in a project charter?

Quality metrics or standards are typically detailed in a quality management plan, which is a subsidiary plan, not a primary component that MUST be in the charter.

The project scope is a fundamental component of a project charter, as it defines the boundaries of the project, specifying what is included and excluded. Clearly defining the scope in the charter ensures that all stakeholders have a shared understanding of the project's objectives and deliverables from the outset.

Action items are granular tasks or steps to be taken, which are too detailed for the high-level summary provided in a project charter.

A Work Breakdown Structure (WBS) decomposes project deliverables into smaller, more manageable components, which is a detailed planning output, not a high-level element of the charter.
