Scripts

1. health_score_calculator.py

Purpose: Multi-dimensional customer health scoring with trend analysis and segment-aware benchmarking.

Dimensions and Weights:

Classification:

• Green (75-100): Healthy -- customer achieving value
• Yellow (50-74): Needs attention -- monitor closely
• Red (0-49): At risk -- immediate intervention required

Usage:

python scripts/health_score_calculator.py customer_data.json
python scripts/health_score_calculator.py customer_data.json --format json

2. churn_risk_analyzer.py

Purpose: Identify at-risk accounts with behavioral signal detection and tier-based intervention recommendations.

Risk Signal Weights:

Risk Tiers:

• Critical (80-100): Immediate executive escalation
• High (60-79): Urgent CSM intervention
• Medium (40-59): Proactive outreach
• Low (0-39): Standard monitoring

Usage:

python scripts/churn_risk_analyzer.py customer_data.json
python scripts/churn_risk_analyzer.py customer_data.json --format json

3. expansion_opportunity_scorer.py

Purpose: Identify upsell, cross-sell, and expansion opportunities with revenue estimation and priority ranking.

Expansion Types:

• Upsell : Upgrade to higher tier or more of existing product
• Cross-sell : Add new product modules
• Expansion : Additional seats or departments

Usage:

python scripts/expansion_opportunity_scorer.py customer_data.json
python scripts/expansion_opportunity_scorer.py customer_data.json --format json

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
