Return to Part 1 Requirements

Statement

The Conceptual Architecture SHALL distinguish Traceability from 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 linksEvidence recordsSupported claimsCross-level relationshipsVerification material

Verification

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

Verification activities include review checks confirming that:

Traceability references identify relationshipsEvidence references identify recorded information supporting claimsTrace links do not replace evidence recordsEvidence records do not replace traceability relationships
