What its author says it does
Copied from the file, not written here
Activates BusinessIntelligence-Pro for KPI design, dashboard strategy, and SQL optimization. Use when you need north star metric and metric tree design, LookML or Looker explore architecture, complex SQL with window functions and CTEs, threshold-based and ML-powered alerting design, or data storytelling for executive audiences.

North Star Metric Framework
- North Star: single metric that captures core product value
- Good example: 'Weekly Active Users who complete a core action'
- Bad example: 'Revenue' (lagging indicator, doesn't capture user value)
- Input metrics (3-5 leading indicators that drive North Star):
- Acquisition: new user signups
- Activation: users reaching aha moment
- Engagement: core action frequency
- Guardrail metrics: must not degrade (e.g., support ticket volume, latency)
- Lagging metrics: revenue, retention — validate North Star theory

SQL Expert Patterns
Window Functions
-- Running total
SUM(revenue) OVER (PARTITION BY user_id ORDER BY date) AS cumulative_revenue
-- Cohort retention
COUNT(DISTINCT user_id) OVER (PARTITION BY cohort_month) AS cohort_size
-- Moving average
AVG(daily_revenue) OVER (ORDER BY date ROWS BETWEEN 6 PRECEDING AND CURRENT ROW) AS rolling_7d_avg
-- Rank within group
ROW_NUMBER() OVER (PARTITION BY customer_id ORDER BY order_date DESC) AS recency_rank
Cohort Analysis CTE Pattern
WITH first_purchase AS (
SELECT user_id, DATE_TRUNC('month', MIN(created_at)) AS cohort_month FROM orders GROUP BY 1
),
cohort_data AS (
SELECT f.cohort_month, DATE_TRUNC('month', o.created_at) AS order_month,
COUNT(DISTINCT o.user_id) AS active_users
FROM orders o JOIN first_purchase f ON o.user_id = f.user_id
GROUP BY 1, 2
)
SELECT cohort_month, order_month,
DATEDIFF('month', cohort_month, order_month) AS months_since_acquisition,
active_users
FROM cohort_data ORDER BY 1, 3;
Dashboard Design Principles
- Answer one question per chart — no chart should require explanation
- Lead with the most important number (large KPI card at top)
- Provide context: comparison to prior period and target
- Drill-down hierarchy: executive → operational → diagnostic
- Traffic light coloring: green (on target), yellow (within 10%), red (>10% off)
Alerting Strategy
- Threshold alerts: metric crosses absolute value (e.g., error rate > 5%)
- Anomaly alerts: metric deviates > 2σ from rolling baseline
- SLA alerts: data freshness older than expected cadence + 30 min
- Alert fatigue rule: < 5 alerts per person per day; tune thresholds quarterly
