Traceability Engineering Skill Guidance

Use When

establishing forward and backward links among goals, requirements, design, code, tests, and evidence; use traceability-matrix for the governance roll-up artefact.
Use this procedure when the required source artefacts are available and Trace model and gap register is the next lifecycle deliverable.

Use traceability-matrix when that neighbouring route owns the decision or deliverable.
Do not invent missing project evidence, standards clauses, thresholds, or stakeholder decisions.

Artefact	Source or provider	Required?	Behaviour when missing
Stable identifiers and approved lifecycle artefacts	Phase owners and project registries	Yes	Stop the affected step, name the missing source, and return only a qualified gap record.
