Final answer:
The scenario fails to meet the definition of a product requirements document because the IT manager made undocumented changes to the user requirements.
Step-by-step explanation:
The scenario fails to meet the definition of a product requirements document because the IT manager made changes to the user requirements without documenting them within the document.
A product requirements document is a critical document that outlines the specific features, functions, and specifications of a product or software. It serves as a guideline for product development and ensures that the final product meets the customer's needs.
By making changes without documenting them, the IT manager deviates from the formal process of capturing and tracking requirements. This lack of documentation can lead to miscommunication, confusion, and a product that fails to meet user expectations.
