Traceability Matrix

Metadata

Key	Value
ID	TM-001
CrossReference	BC-001, SA-001

Version History

Date	Status	Author	Reviewer	Change	Commit
2026-11-06	Proposed	Jens Tirsvad Nielsen	S01	Initial version: BC, SA, PP, MIL-001 to MIL-003 and RC-001 to RC-005	a07d05b

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.

Concern Coverage

No view (architecture, design or use case artifact) exists yet, and none is planned before the milestones: the exercise is one function and the reason for skipping user stories and use cases is recorded in ADR-0001, a task of MIL-001 (accepted). Each concern is delivered by a milestone Go criterion; that is noted in the first column. There is no Architecture Description, so the gaps are not listed there.

Concern (CN-ID)	Views that answer it	Decisions (ADR)	Quality check (TP)	Status
CN-001	none; delivered by MIL-002 Go criteria 1 and 2	none (ADR-0001 does not address it)	none	Gap
CN-002	none; delivered by MIL-002 Go criterion 1	none (ADR-0001 does not address it)	none	Gap
CN-003	none; delivered by MIL-003 Go criteria 1 to 3	none (ADR-0001 does not address it)	none	Gap
CN-004	none; delivered by MIL-002 Go criterion 3	none (ADR-0001 does not address it)	none	Gap
CN-005	none; delivered by MIL-001 Go criterion 3	none (ADR-0001 does not address it)	none	Gap
CN-006	none; delivered by MIL-001 Go criteria 3 and 5	none (ADR-0001 does not address it)	none	Gap
CN-007	none; delivered by MIL-001 Go criterion 1 and MIL-002 Go criterion 6	none (ADR-0001 does not address it)	none	Gap

Open Inconsistencies

#	Views	Inconsistency	Found in (RC-ID)	Status	Resolved in
1	SA-001, BC-001	CN-007 (no runtime dependencies) was traced to Business Case objective 3 (venv and run instructions), which does not cover it	RC-002	Closed	SA-001 version of 2026-11-06
2	BC-001	The constraint "No runtime dependencies unless needed" contradicted success criterion 3 (0 runtime dependencies)	RC-001	Closed	BC-001 version of 2026-11-06
3	PP-001, MIL-002	The plan placed constants.py at MIL-001, while MIL-002 task 1 creates it	informal review of PP-001 (no RC)	Closed	PP-001 version of 2026-11-06

Coverage Notes

• Types with no instance yet: KPI, BMC, BPMN, UCD, US, UC, DM, SSD, OC, SD, DCD, ERD, TP, AD, GOV, DICT. User stories and use cases are skipped on purpose (recorded in ADR-0001); GOV and DICT are not in the plan, which leaves QC-LANG-001 criterion 5 without a dictionary to check against.
• - in Upstream means foundational; in Downstream, nothing is built on it yet; in Last Reviewed, no RC-* exists yet.
• All five reviews are Mode: autonomous, not independent and Go: S01 confirmed criteria 3, 5 and 9 of QC-LANG-001 as a person in chat on 2026-11-06, so BC-001, SA-001 and MIL-001 to MIL-003 are Accepted.
