Analysis Of The Telco Customer Churn Data

Analysis Of The Telco Customer Churn Data Sets

In these modern day competitive business environment, every business strives to grow and mostly need to retain their customers to increase organizational growth, development and effective performance. This analysis focuses on using Customer behavior data to improve Customer Retention. The Churn rate is the number of Customers or subscribers who stop subscribing to a service or company, which means these Customers have “Churned”. Telecommunication companies are concerned about the number of Customers leaving their service.

For this reason, they need to understand who is leaving and why they are leaving. To analyze this, we are provided with data set which includes information about: Customers who left within the last month – the column is called Churn. Services that each Customer has signed up for – Phone, Multiple lines, Internet, Online Security, Online backup, Device Protection, Tech Support, Streaming TV and Movies. Customer Account Information – how long they’ve been a Customer, Contract, Payment Method, Paperless billing, Monthly Charges and Total Charges. Demographic Information about Customers – Gender, Age range, if Customers have Partners and Dependents.

Analyzing data through visualization using Watson Analytics, the key insights are as follows:

1. Most Commonly Used Internet Service is Fiber Optics, as shown in the bar chart.
2. The most used Payment Method and Contract type are Electronic Check and Month-to-Month, respectively.
3. Customer usage of Internet and Phone Services shows Fiber Optics Internet is commonly used with Phone.
4. Most customers prefer the Paperless Statement method, as indicated in the pie chart.
5. Key drivers of churn include Tenure, Total Charges, Monthly Charges, Contract, Online Security, and Internet service. Visualizations show how each driver influences churn individually and in combination.
6. The predictive model for churn, developed using Decision Tree analysis, indicates contracts and thirteen other factors can predict churn with around 80% accuracy.
7. Customers with month-to-month contracts and Fiber Optics Internet are a significant proportion of churned customers, highlighting Contract & Internet Services as primary churn drivers.
8. Tenure significantly influences churn: Customers with tenure less than 5 months are more likely to churn, whereas those with tenure over 5 years are less likely.
9. Total Charges are driven predominantly by Monthly Charges and Tenure, with a predictive model showing a 97% strength in predicting Total Charges based on these factors.

In conclusion, analysis of the Telco Customer Churn Dataset using visualization tools and statistical models such as Watson Analytics, IBM SPSS Modeler, and Excel revealed that the key drivers of customer churn are Tenure, MonthlyCharges, and TotalCharges. Customers with less than 5 months' tenure are at higher risk of churning. Conversely, long-term customers with over 5 years of tenure tend to stay. Based on these insights, tailored customer retention strategies should be implemented: promotional discounts targeting new customers with less than 5 months of tenure, and loyalty reward programs for long-term customers, to minimize churn rates.

Customer churn is a critical concern for telecommunication companies, directly impacting revenue and market competitiveness (Kumar & Reinartz, 2016). Understanding churn behavior through comprehensive data analysis enables proactive strategies to improve customer retention. This paper presents an analytical overview of the Telco Customer Churn dataset, highlighting major drivers, predictive models, and strategic implications.

The dataset encompasses a broad spectrum of customer information, including service usage, billing methods, account tenure, and demographic attributes. Visualization techniques applied via Watson Analytics revealed significant patterns: Fiber Optics is the predominant internet service, with a preference for electronic check payments and month-to-month contracts. Customers also predominantly favor paperless billing, indicating a trend towards digital engagement (Fahim et al., 2020).

Identifying the determinants of churn involves examining both individual and combined factors. The analysis found that tenure, total charges, monthly charges, contract type, online security, and internet service stand out as primary influences (Lemon & Verhoef, 2016). The spiral visualization demonstrated how tenure notably impacts churn rates, with shorter tenures correlating with higher churn. Customers with less than five months of tenure are significantly more likely to leave, aligning with prior research that emphasizes the importance of initial customer experience (Verhoef, 2017).

Further, predictive models developed via decision tree algorithms achieved an accuracy rate of approximately 80% for churn prediction. These models utilized variables such as contract type and service usage to identify at-risk customers effectively. The insights suggest that month-to-month contracts combined with Fiber Optics Internet usage are particularly associated with higher churn propensity, emphasizing the need for tailored retention initiatives (Sun et al., 2019).

Similarly, the analysis of total charges indicates a strong association with tenure and monthly charges, with a predictive strength of 97%. Customers incurring higher charges tend to have longer tenure, implying that cost-related factors influence customer loyalty and satisfaction (Ng & Smith, 2019). Consequently, strategic interventions should focus on providing incentives and loyalty rewards for long-term customers, while offering targeted discounts to newer customers to curtail early churn (Huang & Rust, 2021).

The findings underscore the importance of personalized retention programs informed by data analytics. For instance, implementing promotional discounts for customers with tenure less than 5 months can mitigate initial churn risk. Conversely, reward programs recognizing long-standing customers can reinforce loyalty and reduce churn over the long term. Additionally, service bundling and quality enhancement for high-risk customer segments can further decrease churn rates, driving sustained profitability (Reinartz & Kumar, 2017).

In conclusion, leveraging advanced data analytical approaches provides telecommunication providers with actionable insights into customer behavior. By focusing on key drivers such as tenure, monthly charges, and contract type, companies can develop strategic retention initiatives that align with customer needs and preferences, ultimately fostering long-term loyalty and competitive advantage.
