Key Metric

Identified high-risk customer segments for retention

Overview

This project analyzes customer churn patterns at OurBank to identify key factors influencing customer retention and develop strategies to reduce attrition. Through comprehensive data analysis and interactive Tableau dashboards, we uncovered critical insights into customer behavior and churn risk factors.

Project Objectives

  • Identify key factors influencing customer churn
  • Analyze churn patterns across different customer segments
  • Develop predictive insights to anticipate customer attrition
  • Create interactive dashboards for monitoring retention metrics
  • Provide actionable recommendations for retention strategies

Business Challenge

Customer churn represents a significant challenge for banking institutions. Acquiring new customers is significantly more expensive than retaining existing ones, making churn reduction a critical business priority.

Research Questions

  • What characteristics define high-churn customer segments?
  • Which factors have the strongest correlation with customer attrition?
  • Can we predict which customers are likely to churn?
  • What interventions can reduce churn rates effectively?

Approach

Data Collection & Preparation

The analysis utilized comprehensive customer data including:

  • Account Information: Tenure, account type, balances
  • Transaction Activity: Frequency, volume, patterns
  • Demographics: Age, geography, income levels
  • Service Usage: Product adoption, digital banking engagement
  • Churn Status: Historical retention and attrition data

Analysis Methodology

  1. Exploratory Data Analysis: Examined distributions and patterns in customer behavior
  2. Segmentation Analysis: Grouped customers by churn risk and characteristics
  3. Feature Analysis: Identified key variables correlated with churn
  4. Visualization Development: Created Tableau dashboards for interactive exploration
  5. Pattern Recognition: Uncovered trends and anomalies in customer retention

Tools & Technologies

  • Tableau: Interactive dashboards and data visualization
  • Microsoft Excel: Data cleaning, transformation, and preliminary analysis
  • Data Analytics: Statistical analysis and correlation studies
  • Business Intelligence: Dashboard design and stakeholder communication

Key Findings

High-Risk Customer Segments

The analysis identified specific customer segments with elevated churn rates:

  • Low Account Tenure: Newer customers show higher attrition rates
  • Minimal Transaction Activity: Inactive accounts are at higher risk
  • Limited Product Adoption: Single-product customers more likely to leave
  • Low Engagement: Customers not using digital banking services

Key Churn Indicators

Several factors emerged as strong predictors of customer churn:

Transaction Activity - Significant decrease in transaction frequency precedes churn - Declining average transaction values signal disengagement - Extended periods of account inactivity

Account Tenure - First 12 months represent critical retention period - Churn risk decreases significantly after 2+ years - Onboarding experience impacts long-term retention

Product Engagement - Customers with multiple products show lower churn - Digital banking adoption correlates with retention - Service utilization depth matters more than breadth

Recommendations

Immediate Retention Actions

  1. Early Warning System
  2. Implement real-time monitoring of churn risk indicators
  3. Trigger proactive outreach for at-risk customers
  4. Deploy retention offers before churn occurs

  5. Enhanced Onboarding Program

  6. Focus on first 12 months of customer relationship
  7. Increase touchpoints and engagement opportunities
  8. Ensure successful adoption of key banking services

  9. Reactivation Campaigns

  10. Target inactive accounts with personalized offers
  11. Incentivize transaction activity and engagement
  12. Simplify return-to-active pathways

Strategic Initiatives

  • Product Cross-Selling: Increase multi-product adoption to strengthen relationships
  • Digital Banking Promotion: Drive adoption of online and mobile banking
  • Personalization: Tailor communications and offers based on customer segments
  • Customer Experience: Improve service quality touchpoints identified as pain areas
  • Predictive Modeling: Develop machine learning models for churn prediction

Data Visualizations

The Tableau dashboard includes:

  • Churn Rate Trends: Historical and current attrition patterns
  • Customer Segmentation: Visual breakdown of churn by demographics
  • Risk Scoring: Heat maps showing high-risk customer groups
  • Feature Correlation: Analysis of factors most predictive of churn
  • Retention Metrics: KPIs for monitoring program effectiveness

Business Impact

Value Delivered

  • Risk Identification: Clear visibility into which customers are at risk
  • Actionable Insights: Specific factors that can be addressed through interventions

  • Improved customer lifetime value
  • More efficient allocation of retention marketing budget
  • Enhanced understanding of customer behavior and preferences
  • Better onboarding and customer experience strategies

Next Steps

Future Analysis

  • Machine Learning Models: Implement logistic regression and decision trees for churn prediction
  • Advanced Segmentation: Develop more granular customer clustering
  • Python Integration: Combine Tableau with Python for advanced analytics
  • Power BI Expansion: Create additional dashboards for different stakeholders
  • Real-Time Analytics: Build automated monitoring and alerting systems

Implementation Roadmap

  1. Pilot retention program with highest-risk segment
  2. Measure impact and refine approach
  3. Scale successful interventions across customer base
  4. Continuously monitor and optimize retention strategies
