# Traceability Matrix

## Metadata

## Purpose

Tracks backward/forward links between artifact instances so that the Business Case's
cross-artifact traceability success criterion is measurable. A row is added or
updated whenever an artifact instance is created or reviewed.

- No Design Class Diagram, ERD, KPI, BMC or BPMN exists yet. `-` in Downstream means nothing is built on the artifact yet.
