Which of the following is a true statement about the identification of requirements?

The statement that each requirement must have a unique identifier is essential in the context of requirements management. Unique identifiers serve multiple purposes, including facilitating tracking, ensuring traceability, and avoiding confusion among stakeholders. When requirements are uniquely identifiable, it becomes easier to reference, discuss, and manage them throughout the project lifecycle. This uniqueness is particularly crucial when dealing with large projects where numerous requirements may exist concurrently.

Moreover, a unique identifier allows for clear communication among team members and stakeholders, ensuring everyone is on the same page regarding which specific requirement is being referred to, thus streamlining the management process. With clear identifiers, it’s also easier to trace back to original needs and verify that they have been met in the final solution.

In contrast, the other options present statements that do not align with best practices in requirements management, as having identifiers is crucial for maintaining clarity and organization.
