Today, we are discussing customer churn, which is the rate at which customers leave a business. Can anyone say why understanding churn is important for companies, especially in telecom?
It’s important because losing customers means losing revenue.
Exactly! Telecom companies face a lot of competition, so retaining customers is crucial. Do you think they can predict which customers might leave?
Maybe they can use data analytics to help with that!
Right again! Predictive analytics can provide insights into customer behavior. Let’s summarize: What needs to be considered when addressing customer churn?
Understanding the reasons customers might leave and looking at data to find patterns!
Great summary! Understanding customer churn is about analyzing data to implement retention strategies.

• Problem: High customer churn was hurting revenues.
Detailed Explanation
In business, customer churn refers to the loss of clients or customers. In the telecom industry, this can significantly impact revenues, as acquiring new customers is often more costly than retaining existing ones. The high churn rates indicate that the company is losing subscribers faster than it can replace them, leading to a negative effect on profitability and overall business performance.
Examples & Analogies
Imagine a restaurant that constantly loses regular customers because of poor service or high prices. Just like this restaurant, a telecom company needs to keep its customers happy, or they will switch to competitors, hurting its income.

• Approach: Built a classification model using call, internet, and complaint data.
Detailed Explanation
To address the problem of customer churn, the telecom company chose to develop a classification model. Classification models are a type of machine learning method used to predict which category or class new instances belong to based on past data. In this case, the model utilized various data points, including call records, internet usage, and customer complaints to identify patterns that could indicate a customer was likely to churn.
Examples & Analogies
Think of this approach as a teacher assessing students' performance based on their past grades and behavior. By analyzing these indicators, the teacher can predict who might struggle in the future and give them extra help, just like the telecom company targets at-risk customers with retention strategies.
