Methodology & Results

Three-Phase Strategic Implementation

Phase 1: Data Analysis & Modeling

  • Analyzed 71,047 customer records using calibration and validation datasets
  • Built decision tree model achieving 65.59% recall and 60.03% accuracy
  • Developed logistic regression model for coefficient interpretation
  • Identified key churn drivers: equipment age, retention calls, refurbished phones

Phase 2: Model Comparison & Selection

  • Compared decision tree vs logistic regression performance
  • Selected decision tree for superior recall (65.59% vs 57.06%)
  • Prioritized recall over precision for churn prediction
  • Applied lift analysis showing 1.33x improvement in top decile

Phase 3: Strategic Implementation

  • Designed personalized retention offers for high-risk customers
  • Created customer segmentation based on churn probability
  • Developed ROI-optimized campaign strategies
  • Implemented proactive vs reactive retention framework

Model Innovation: Selected decision tree over logistic regression based on superior recall performance (65.59% vs 57.06%), recognizing that missing a churner is costlier than targeting a non-churner. The model identified equipment age (Eqpdays) and customer tenure (Months) as the most critical churn predictors.

Key Findings & Performance

Strategic Success: The targeted retention approach achieved exceptional business outcomes with 757% ROI and $4.39M LTV improvement, demonstrating the power of data-driven customer relationship management in the competitive telecommunications industry.

1,667 Customers Targeted
$580K Total Investment Cost

Critical Model Insights

  • Equipment Age (Eqpdays): Most critical predictor - customers with older phones (>306 days) show significantly higher churn rates
  • Customer Tenure (Months): Longer relationships reduce churn risk - newer customers (<13 months) are at highest risk
  • Retention Calls (Retcall): Strong churn indicator - customers requiring retention calls are 76.6% more likely to churn
  • Refurbished Phones (Refurb): 29.5% higher churn likelihood for customers with refurbished devices
  • Personalized Interventions: Targeted offers based on individual churn probability (ranging from 17% to 77%)

Strategic Retention Framework

Model Selection Methodology

  • Decision tree selected over logistic regression for superior recall (65.59% vs 57.06%)
  • Higher lift in top decile (1.33 vs 1.30) for better targeting efficiency
  • Prioritized recall to minimize costly false negatives (missed churners)
  • Equipment age (Eqpdays) and tenure (Months) identified as top predictors

Personalized Retention Strategies

  • High-risk customers (77% churn probability): Device upgrades and loyalty incentives
  • Low-risk customers (17% churn probability): Minimal intervention and cross-sell opportunities
  • Targeted offers addressing specific pain points: network issues, device age, service quality
  • Expected churn reduction: 30-40% for high-risk, 5% for low-risk segments

Expected Outcomes: Implementation of this comprehensive retention framework demonstrates how predictive analytics can transform customer relationship management from reactive to proactive, delivering substantial ROI improvements while enhancing customer satisfaction and loyalty in competitive markets.
