Traçabilité des exigences
Requirements traceability is the practice of linking each requirement to its source and to everything downstream that fulfills or verifies it, such as designs, code, and test cases. It lets a team follow any requirement forward and backward, so they can see what a change affects and prove that every requirement has been built and tested.
What it means
Traceability answers two questions that come up constantly on a serious project: where did this requirement come from, and what does it touch. Follow it backward and you reach the stakeholder need or regulation that prompted it. Follow it forward and you reach the design, the code, and the tests that satisfy it. Those links are what turn a pile of requirements into something you can actually reason about.
In safety-critical work, traceability is often mandatory. Standards behind medical, aerospace, and automotive software expect evidence that every requirement is covered by a test and that no test exists without a reason. Native Azure DevOps can link work items to each other, but rolling those links up into a complete, auditable view is where dedicated tooling like Modern Requirements comes in.
In practice
An avionics team changes a requirement about how the system responds to a sensor failure. Because that requirement is traced to three design elements and five test cases, the change immediately shows which tests need to be rerun and which parts of the design need another look. Without the links, someone would be searching documents by hand and hoping they caught everything.
