Best Practices

Do's

• Limit to 5-7 KPIs - Focus on what matters
• Show context - Comparisons, trends, targets
• Use consistent colors - Red=bad, green=good
• Enable drilldown - From summary to detail
• Update appropriately - Match metric frequency

Don'ts

• Don't show vanity metrics - Focus on actionable data
• Don't overcrowd - White space aids comprehension
• Don't use 3D charts - They distort perception
• Don't hide methodology - Document calculations
• Don't ignore mobile - Ensure responsive design

Troubleshooting

MRR shown on dashboard contradicts finance's number

The most common cause is inconsistent treatment of annual plans. Finance may prorate to a daily rate while the dashboard normalizes to monthly. Align on a single formula and document it directly on the dashboard card:

-- Explicit formula shown in tooltip / data dictionary
-- Annual plans: divide total contract value by 12
-- Quarterly plans: divide by 3
-- Monthly plans: use as-is
CASE subscription_interval
    WHEN 'monthly'   THEN amount
    WHEN 'quarterly' THEN amount / 3.0
    WHEN 'yearly'    THEN amount / 12.0
END AS normalized_mrr

Dashboard shows green but product team reports users complaining

The dashboard likely tracks system uptime (a lagging indicator) but not user-facing quality metrics. Add customer-perceived metrics alongside infrastructure metrics:

Retention cohort looks flat — no variation between cohorts

Check whether the cohort query is partitioning by signup month correctly. A common bug is using created_at::date instead of DATE_TRUNC('month', created_at), which groups by day and produces cohorts too small to show trends:

-- Wrong: too granular, cohorts are too small
DATE_TRUNC('day', created_at) AS cohort_date

-- Correct: monthly cohorts
DATE_TRUNC('month', created_at) AS cohort_month

Real-time dashboard hammers the database

A live dashboard refreshing every 10 seconds with complex cohort SQL will degrade production query performance. Separate OLAP workloads from OLTP by writing pre-aggregated metrics to a summary table via a scheduled job, and have the dashboard read from that:

# Scheduled every 5 minutes via cron/Celery
def refresh_mrr_summary():
    conn.execute("""
        INSERT INTO kpi_snapshot (metric, value, snapshot_at)
        SELECT 'mrr', SUM(...), NOW()
        FROM subscriptions WHERE status = 'active'
        ON CONFLICT (metric) DO UPDATE SET value = EXCLUDED.value
    """)

Alert thresholds fire constantly, team ignores them

Static thresholds set once and never reviewed cause alert fatigue. Use dynamic thresholds based on rolling averages so alerts fire only when the metric deviates significantly from its own baseline:

# Alert if current value is > 2 standard deviations from 30-day rolling mean
def is_anomalous(current: float, history: list[float]) -> bool:
    mean = statistics.mean(history)
    stdev = statistics.stdev(history)
    return abs(current - mean) > 2 * stdev
