1. About the Use Case :
Customer churn alternatively referred to as customer attrition indicates that the customer (or user or subscriber etc.) cease to do business with the company or service provider. Higher value of churn suggests that the customer is no longer willing to purchase goods or services from your business. The ability to predict that a particular customer is at a high risk of churning, while there is still time to do something about it, represents a huge additional potential revenue source for any business. Furthermore, it is always more difficult and expensive to acquire a new customer than it is to retain a current paying customer. Being a critical metric in hindering business growth, companies must be aware about its customer churn rate in order to monitor revenue success as well as determine strategies for customer retention.
