Compression Teach-Back & Repair
5-minute teach-back
Teach the chapter with only these verbs:
ARCHITECT → LOAD → DELIVER → OPERATE → GOVERN → MEASURE
Your explanation should include: - Inmon vs Kimball and storage roles; - history/grain and atomic detail; - historical load, CDC and low latency; - six activities, mapping/remediation/transformation/population; - BI user segmentation, self-service and OLAP; - product lifecycle/release/monitoring; - Metadata/lineage/acceptance; - usage/coverage/performance/satisfaction.
2-minute teach-back
Explain only: Inmon · Kimball · ODS/DW/Mart · CDC/low latency · six activities · Metadata/lineage · metrics.
If you cannot fit the distinctions into two minutes without confusing roles, return to Battle Cards rather than rereading the full chapter.
30-second teach-back
DW/BI turns integrated historical data into trusted analytical products. Architecture controls where data lives, population controls how it arrives, BI matches access to user needs, Metadata/lineage/governance create trust, and operations plus metrics prove the product works and is used.
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.
Repair protocol
- Mark the exact missed prompt—not “Chapter 11 weak.”
- Classify the miss: vocabulary, discrimination, sequence, architecture role, source evidence, user/BI type, governance/role, or metric.
- Review only the matching Guided Learning section + Battle Card + source anchor.
- Close the material.
- Reconstruct the answer from memory.
- Retest after a delay without rereading first.
- Add to Artifact 08 only if the miss is real and recurring, or if timing/confidence repeatedly exposes the same weakness.
Final gate
Before calling Chapter 11 mastered, you should be able to rebuild from blank paper: - Inmon vs Kimball; - staging/ODS/DW/mart/cube; - five CDC methods; - trickle/messaging/streaming; - six activities; - mapping/remediation/transformation; - product lifecycle; - Metadata/lineage/impact; - the five-part value evidence stack.
