Compression Teach-Back & Repair
5-minute teach-back
Teach the whole chapter using this route:
meaning/types → sources → architectures → lifecycle → metamodel/standards → integration/delivery → lineage/impact → Governance/security → metrics
A good explanation should include at least one example and one confusion pair at each major stage.
2-minute teach-back
Explain only: - Business / Technical / Operational Metadata; - Glossary / Dictionary / Catalog; - Centralized / Distributed / Hybrid / Bi-Directional; - five core activities; - Data Model vs Metamodel; - Integrate vs Deliver; - As Designed vs As Implemented; - Lineage vs Impact; - seven metric families.
30-second teach-back
Metadata Management turns scattered knowledge about data into governed, integrated, accessible context. Strategy and requirements drive architecture; source Metadata is harvested and managed as a product; lineage and impact make dependencies understandable; Governance protects quality and security; metrics prove coverage, trust, stewardship, and use.
0 / 1 / 2 self-score
- 2 points: answered from memory with the deciding distinction and a correct example.
- 1 point: broadly correct but vague or missing the deciding clue.
- 0 points: wrong, guessed, or needed the source immediately.
Targeted repair sequence
- Mark the exact miss—do not write “Metadata architecture weak.” Write “Distributed vs Hybrid: forgot that Hybrid has some central persistence.”
- Classify the miss: vocabulary/confusion pair; source selection; architecture clue; sequence; role/Governance; lineage direction; metric mismatch; qualifier; overthinking.
- Review only the controlling Guided lesson + Battle Card + source anchor.
- Close the material.
- Restate the rule in one sentence.
- Create a changed-fact example that makes the nearest alternative correct.
- Retry after a delay.
Artifact 08 gate
Do not prefill Error Repair. Only repeated real misses, slow decisions, confidence mismatch, or recurring confusion from actual practice should populate Artifact 08.
