Output Formats

All scripts support two output formats via the --format flag:

• text (default): Human-readable formatted output for terminal viewing
• json: Machine-readable JSON output for integrations and pipelines

Clarify First

Before running the analysis, settle the inputs below. When one is missing or vague and would change the result, ask about it; when it wouldn't, use a sensible default and say which one you used.

• Which analysis: health score, churn risk, or expansion opportunity (selects which of the three scripts and its input schema).
• Customer segment: Enterprise / Mid-Market / SMB (segment-aware thresholds change every Red/Yellow/Green and risk-tier cutoff).
• Previous-period data availability: without it, trend analysis (declining vs improving) cannot run.
• Renewal date / contract end: drives the time-to-renewal urgency multiplier in churn scoring.

Ask about the two or three inputs that matter most for this request, not the whole list. If the user wants a result straight away, produce it and state your assumptions at the top.

---

Best Practices

1. Score regularly: Run health scoring weekly for Enterprise, bi-weekly for Mid-Market, monthly for SMB
2. Act on trends, not snapshots: A declining Green is more urgent than a stable Yellow
3. Combine signals: Use all three scripts together for a complete customer picture
4. Calibrate thresholds: Adjust segment benchmarks based on your product and industry
5. Document interventions: Track what actions you took and outcomes for playbook refinement
6. Prepare with data: Run scripts before every QBR and executive meeting

---

Limitations

• No real-time data: Scripts analyze point-in-time snapshots from JSON input files
• No CRM integration: Data must be exported manually from your CRM/CS platform
• Deterministic only: No predictive ML -- scoring is algorithmic based on weighted signals
• Threshold tuning: Default thresholds are industry-standard but may need calibration for your business
• Revenue estimates: Expansion revenue estimates are approximations based on usage patterns

Troubleshooting

Problem	Likely Cause	Solution
Health scores do not correlate with actual churn	Default thresholds do not match your product	Calibrate segment thresholds using historical churn data; compare 90-day retained vs churned cohorts
All accounts show as Yellow	Thresholds too strict or data quality issues	Review input data completeness; adjust benchmarks in health_score_calculator.py constants for your industry
Churn risk scores are uniformly low	Missing key signals (champion left, competitor mentions)	Ensure all signal categories have data; missing data defaults to low risk, which understates actual risk
Expansion scores do not reflect reality	Product usage data is incomplete or stale	Verify product_usage fields cover all modules; run with fresh data exports from your product analytics
Scripts error on input data	JSON format does not match expected schema	Reference the Input Requirements section for exact JSON structure; validate JSON before running
Trend analysis shows no change	Previous period data not provided	Include the previous_period block in health score input for meaningful trend comparison
Intervention recommendations feel generic	Segment is not specified	Always include the segment field (enterprise, mid-market, smb) for segment-appropriate playbooks

---

Success Criteria

• Health scores run weekly for Enterprise, bi-weekly for Mid-Market, monthly for SMB accounts
• Portfolio health distribution: 60%+ Green, less than 15% Red
• Churn risk critical accounts have executive escalation within 48 hours
• Expansion pipeline generated covers 20%+ of net retention target
• Health score trends (improving/declining) drive proactive outreach before renewal window
• QBR preparation includes health score, risk assessment, and expansion opportunities for every strategic account
• Intervention playbooks followed for all High and Critical risk accounts

---

Scope & Limitations

• In scope: Customer health scoring, churn risk analysis, expansion opportunity identification, segment benchmarking, trend analysis, QBR preparation
• Out of scope: CRM integration, real-time monitoring, predictive ML modeling, automated outreach
• Data dependency: Scripts analyze point-in-time JSON snapshots; data must be exported manually from your CRM/CS platform
• Deterministic scoring: All analysis is algorithmic based on weighted signals -- no machine learning predictions
• Threshold tuning: Default thresholds are industry-standard benchmarks; calibrate for your specific product and customer base
• Revenue estimates: Expansion revenue estimates are approximations based on usage patterns, not binding forecasts

---

Integration Points

• churn-prevention -- High-risk accounts from churn_risk_analyzer.py should trigger cancel flow optimization and save offer review
• revenue-operations -- Expansion opportunities feed into pipeline forecasting; health scores inform forecast confidence
• onboarding-cro -- When health scores show low usage in early lifecycle, the root cause is often poor activation
• pricing-strategy -- When expansion analysis reveals pricing as a barrier to upsell, feed into pricing-strategy for packaging review
• competitive-teardown -- When churn risk signals include competitor mentions, use teardown data to build counter-positioning
