Which is NOT a purpose of a Product Description?

Defining time and cost to produce the product is a valid component captured in the Product Description to inform work package and stage planning.

A Product Description specifies quality criteria and quality methods (what standards the product must meet and how it will be assessed), but the identification of quality reviewer skills is handled through other project management artifacts such as the Quality Management Strategy or team role descriptions. The Product Description's scope is the product itself, not the competency profile of those performing quality checks.

Defining the function and appearance of the product is a core purpose of the Product Description, addressed through its purpose, composition, and format sections.

Defining the development skills required to produce the product is explicitly included in the Product Description to ensure appropriate resources are assigned to build it.
