Quality Criteria checklist (QC)

A QC checklist is the reusable review checklist for one artifact type. It lives in the framework (framework/qc/qc-<type>.md), is project-independent, and must never name or link a real artifact instance (no [BC-001], no RC-*, no stakeholder IDs). Refer to types generically ("the Stakeholder Analysis").

• ID: QC-<short-name>-<version> (e.g. QC-BC-001); the version starts at 001 and only changes when the checklist itself is revised.
• Create: new-artifact.sh QC --id QC-XX-001 --file framework/qc/qc-<type>.md --cite QC-<adjacent>=framework/qc/qc-<adjacent>.md ...
• CrossReference: the QC checklists immediately backward and forward in Larman's chain, in both directions:

QC-SA → QC-BC → { QC-BMC, QC-BPMN, QC-KPI } → QC-MIL
QC-BC, QC-SA → QC-UCD → { QC-US, QC-UC }
QC-UC → QC-DM → QC-SSD → QC-OC → QC-SD → QC-DCD → QC-ERD
QC-ADR ↔ QC-DCD, QC-ERD
QC-DCD, QC-ADR → { QC-PY, QC-CL, QC-CPP, QC-CS }   (language code checklists)

Cross-cutting checklists

QC-LANG-001 (framework/qc/qc-language-domain.md, language and domain) is not tied to one artifact type. Apply it together with the checklist of the artifact's own type to every type the registry marks "Written in the PO language"; the review record (RC) lists both checklists and keeps the rows of each. It has an ID in the QC-<short-name> form like the others, but the short name LANG is not an artifact type: there is no LANG instance, template or catalog row. Add another cross-cutting checklist only when a rule applies to several types and does not belong in any one of their checklists.

Version History statuses

The statuses are Proposed, Accepted, Rejected and Deprecated, as for every artifact type (rule in the artifact skill, "Version History rule").

Required sections (after Metadata / Version History)

• Purpose — why this type matters, what decision it supports.
• Quality Criteria Checklist — # | Criterion | Level | ISO/IEC 25010 Characteristic(s) | Notes. Level is Mandatory (baseline every instance must meet) or Optional (advanced, may be deferred); a checklist with an extra column (e.g. Format) keeps Level right after Criterion. Every criterion is tagged with at least one of the eight ISO/IEC 25010:2023 characteristics (Functional Suitability, Performance Efficiency, Compatibility, Usability, Reliability, Security, Maintainability, Portability). Never add an untagged criterion.
• Common Defects — anti-patterns a reviewer rejects on sight.
• Traceability Rule — Backward / Forward bullets with the same [QC-*] labels as CrossReference.

Also add an entry to framework/CHANGELOG.md. Reviews of real instances are recorded in the project as RC-* records, not in the checklist.
