A complete set of links provides little assurance if those links connect the wrong revisions, configurations, or evidence. This is where apparently mature traceability systems can become difficult to defend. Every requirement may have a verification reference, yet the referenced test may have been executed against an earlier design configuration. 

The problem often surfaces after several design changes. A requirement is revised, a risk control changes, or a design output is replaced, but existing relationships remain untouched because no link appears to be missing. The traceability report still shows 100 percent coverage. 

A stronger review asks whether each relationship remains valid for the approved product configuration being assessed. That means checking revision state, applicability, effectivity, change history, and the configuration against which objective evidence was generated. 

During inspection, being able to produce a complete matrix quickly is useful. Being able to demonstrate that its relationships accurately represent the product configuration under review carries far more weight. 

Existing verification evidence should be reconsidered whenever the change affects the configuration assumptions under which that evidence was generated. A test can remain scientifically sound while no longer proving what the organization needs it to prove for the changed device. 

This issue frequently appears with changes that seem localized. A software modification, component substitution, interface change, revised risk control, or altered user requirement may leave the original verification method untouched. The difficult question is whether the previous result still applies to the new configuration. 

Change assessment should therefore examine the relationship between the changed object and the evidence, including indirect dependencies. If previous evidence is retained, the record should explain why the tested configuration remains representative and why the change does not invalidate the original conclusion. 

Weak justification creates substantial rework later because teams may discover during submission preparation, design review, or inspection that accepted legacy evidence cannot be confidently connected to the current device. 

Ownership has to extend across functional boundaries because no single department can maintain reliable traceability if each team controls only its own records. Engineering may own requirements, Quality may oversee risk management, V&V may control testing, and Configuration Management may govern product revisions. The relationships between those records still require defined accountability. 

Governance breaks down when each source document is correctly controlled but nobody is responsible for determining whether cross-functional relationships remain correct after change. This produces a familiar inspection problem: every department can produce its records, but reconstructing the current product configuration requires several people and considerable interpretation. 

Effective ownership defines who establishes relationships, who can modify them, who evaluates affected relationships during change, and who verifies that the resulting configuration remains coherent. 

A useful test is simple: after a significant change, can the organization identify affected requirements, risks, outputs, and evidence without relying on institutional memory? If experienced employees have to reconstruct those connections manually, the control model remains fragile. 

Trying to rebuild every historical relationship at once usually creates enormous effort without proportional regulatory value. A more practical approach starts with the currently approved product configuration and the information needed to support present design, risk, verification, and change decisions. 

Legacy products often contain decades of revisions, superseded specifications, historical test reports, transferred records, and inconsistent identifiers. Attempting to convert all of that history into perfect structured traceability can introduce new errors while consuming resources needed for current controls. 

Priority should be given to safety-critical requirements, significant risk controls, current design outputs, essential verification evidence, unresolved issues, and areas likely to be affected by future changes. Gaps discovered during this work should be assessed for their actual quality and regulatory significance rather than treated automatically as documentation remediation. 

The transition becomes defensible when its scope, priorities, exclusions, and rationale are documented. Regulators are better served by reliable traceability for the current configuration than by an ambitious reconstruction that creates the appearance of completeness without trustworthy relationships.
