[[dido:99_annexes:annex-d-requirements:part-01:start|Return to Part 1 Requirements]]

===== Statement =====

The Conceptual Architecture SHALL distinguish [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] from [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]].

===== Source =====

Part 1, Section 13.6: Separation of Concerns Requirements.

===== Rationale =====

Traceability identifies relationships among architectural, logical, implementation, deployment, and evidence elements. Evidence identifies recorded information that supports a claim. The two concerns work together, but they serve different architectural purposes.

This requirement prevents a trace link from being treated as evidence and prevents evidence records from being treated as the relationship model that connects architectural concerns.

===== Applies To =====

This requirement applies to Traceability and Evidence references within the Conceptual Architecture.

It applies specifically to:

  * Trace links
  * Evidence records
  * Supported claims
  * Cross-level relationships
  * Verification material

===== Verification =====

Verification SHALL confirm that the Conceptual Architecture distinguishes Traceability from Evidence.

Verification activities include review checks confirming that:

  * Traceability references identify relationships
  * Evidence references identify recorded information supporting claims
  * Trace links do not replace evidence records
  * Evidence records do not replace traceability relationships
