Introduction
In today’s competitive telecom industry, customer retention is crucial. Losing customers not only impacts revenue but also incurs higher acquisition costs. In this case study, I demonstrate a comprehensive Telecom Customer Churn Analysis using a multi-page Power BI report. This analysis leverages data analytics to understand churn drivers, segment customer demographics, assess contract and service utilization, and identify high-risk customers for proactive retention measures.
Project Objectives
- Identify key factors influencing customer churn.
- Segment customers based on demographics, contracts, and service usage.
- Analyze customer support interactions as potential churn drivers.
- Highlight high-risk customer segments for targeted retention strategies.
- Present actionable insights through interactive dashboards.
Data & Methodology
The analysis uses a telecom customer churn dataset comprising over 7,000 records. The data model is built using a star schema:
- Fact Table: FactCustomerChurn (storing transactional data like tenure, monthly charges, support tickets, and churn flag)
- Dimension Tables: DimCustomer, DimContract, DimService, and DimSupport provide detailed attributes for customer demographics, contract details, service utilization, and support interactions.
Using Power BI, I developed a six-page interactive report with multiple visualizations and KPIs that enable business stakeholders to quickly grasp key trends and drill down into detailed insights.
