Requirements traceability is often discussed in terms of what happens after a requirement exists: which design implements it, which story delivers it, which test verifies it and what changes if the requirement moves.
There is another link that can disappear much earlier.
What evidence caused the requirement to exist in the first place?
A requirement may have begun as one sentence in a stakeholder workshop, part of a longer discussion, a clarification during an interview or a condition buried inside meeting notes.
Once that evidence is rewritten into a requirements document, the requirement can remain while its origin gradually becomes harder to reconstruct.
That is why useful traceability should begin at the source evidence.
Where the traceability chain can break
A conventional workflow often involves several perfectly reasonable transformations.
A conversation becomes notes.
Notes become analysis.
Analysis becomes requirements.
Requirements are revised, grouped, prioritised and eventually carried into delivery.
The problem is not any one of those steps.
The problem appears when the relationship between them is not carried forward.
A requirement can still have an identifier, an owner and a status while the evidence that originally justified it is sitting somewhere else entirely.
When someone later challenges the requirement, the BA may then have to reconstruct the history from transcripts, meeting notes and memory.
What source-linked traceability changes
Antozoe approaches the problem by retaining the relationship between an artefact and the stakeholder evidence supporting it.
For transcript-based analysis, a requirement, user story or business rule can remain connected to the source transcript it came from.
The source is therefore not only something consulted during the initial analysis.
It remains part of the project's working evidence.
That changes the nature of a review conversation.
Instead of treating the current wording as the entire history of the requirement, the BA can go back to the evidence and distinguish between several different possibilities.
Perhaps the stakeholder clearly stated the need and now wants to change it.
Perhaps the original statement was ambiguous.
Perhaps two stakeholders expressed different expectations.
Or perhaps the current requirement contains an interpretation that needs to be reconsidered.
Those are very different situations, even when they initially appear as the same question: "Why is this requirement here?"
Clarity scoring: a signal, not a verdict
Traceability tells the analyst where the requirement came from.
It does not, by itself, establish whether the requirement is sufficiently clear.
Antozoe therefore allows requirement clarity to remain visible as part of the review process.
A clarity score is most useful when treated as a signal for analyst attention rather than a declaration that a requirement is objectively good or bad.
A lower-confidence or less-clear requirement can prompt another question, another stakeholder discussion or further refinement.
Human review and approval remain separate.
That separation matters because requirement quality cannot be reduced to a number alone.
Protecting the human decision
Governance also matters after an artefact has been reviewed.
If a BA manually changes an artefact, a later analysis run should not quietly erase that decision.
Antozoe protects manually edited artefacts from silent replacement. Where later analysis produces an alternative version, that alternative does not automatically become the current artefact.
The BA reviews the available version and decides what progresses.
This creates a useful distinction between system analysis and analyst decision.
One can inform the other without silently replacing it.
Traceability becomes useful when something changes
The value of source evidence is easiest to see when a project stops being straightforward.
A stakeholder challenges scope.
A requirement changes.
Two teams remember a decision differently.
A new stakeholder asks why a particular rule exists.
The project moves far enough forward that the original workshop is no longer fresh in anyone's memory.
At that point, traceability is no longer documentation housekeeping.
It becomes a way of separating evidence, interpretation and change.
A source-linked requirement can show what supported the original analysis while still allowing the organisation to make a different decision today.
That is an important distinction.
Traceability should not freeze a project in the past.
It should make the path to the present understandable.
And the strongest place for that path to begin is not the finished requirement.
It is the evidence that gave the requirement a reason to exist.
