Book 7 · Lesson 7.1
Team Radar KPI dictionary
- Map Postgres/Redis signals to manager outcomes
- Explain friction index formula on the dashboard
- Connect eval pass rate to evals/ CI gate
Prerequisites: 6.6
Book 7 opens Stage 5 quality systems — EM leadership through measurable signals, not heroics.
| Signal | Outcome | UI |
|---|---|---|
avg_sentiment | Team morale proxy | Manager KPIs |
high_risk_count | Security attention queue | Manager KPIs |
friction_index | Delivery drag composite | Manager KPIs |
eval_pass_rate | AI enrichment quality | Eval pass rate |
Four KPI cards
| Signal | Manager question |
|---|---|
| avg_sentiment | Is morale trending down? |
| high_risk_count | What needs security attention? |
| friction_index | Is delivery drag rising? |
| eval_pass_rate | Is AI enrichment still trustworthy? |
Formulas live in docs/stage5-quality.md — refresh radar after pnpm evals:write-metrics.
Lab
Open :5174, read each card aloud, then trace the SQL source in services/analyzer/.
Teach-back prompt
Why is eval pass rate a manager KPI and not just an engineer CI artifact?
