What is the term for the ability to identify related items in documentation and software, especially linking requirements and tests?

The ability to identify related items in documentation and software, particularly the connection between requirements and tests, is known as traceability. This concept is essential in both software development and testing as it ensures that all requirements are addressed by corresponding tests. Traceability allows teams to track the origins and relationships of various elements throughout the development lifecycle.

By maintaining traceability, teams can pinpoint which requirements are covered by tests and determine if any requirements are left unaddressed. This process significantly aids in impact analysis when changes occur, ensuring that all impacted areas are revisited and validated. Additionally, traceability enhances communication among team members and stakeholders, providing clear visibility into the relationships between requirements, design, implementation, and testing efforts.

In this context, while coverage refers to how well the tests address requirements, it does not inherently imply the link between them, making traceability the more precise term. Document review is more focused on evaluating the content and accuracy of documents, and quality control pertains to the overall processes and practices ensuring product quality rather than specific item identification.
