Which of the following is NOT a major section in a requirement document?

The product backlog is primarily a tool used in Agile project management, particularly within frameworks like Scrum. It is a dynamic list of work items that need to be addressed for project completion, typically consisting of user stories and features prioritized by value and effort. While it is crucial for managing upcoming tasks and ensuring the team focuses on the highest-priority work, it is not a direct section within a requirement document itself.

In contrast, user story owner refers to the person responsible for ensuring the user story meets user needs, change summary captures modifications made to requirements, and standard description provides a detailed explanation of specific requirements. All of these elements directly relate to documenting and tracking requirements for software development, while the product backlog serves more as an operational tool rather than a structured section of a requirement document. Thus, identifying it as NOT a major section aligns with the understanding of the purpose and structure of requirement documents in a software development context.
