====== 11.9 Traceability Preserves Layering ====== [[fxdemo:01-part:start | Go to Top ]] [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] connects conceptual elements, logical elements, implementation artifacts, deployment artifacts, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]]. It allows reviewers to understand how a concern moves through the document set without allowing later layers to redefine earlier layers. A logical element traces to a conceptual element. An implementation artifact traces to a logical element. A deployment artifact traces to an implementation artifact. [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] traces to the claim, behavior, artifact, or condition it supports. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
