While almost every mobile operator has a reactive retention strategy in place for preventing subscriber churn, few have developed proactive retention strategies for doing so, failing to benefit from this practice proven to stem the tide of customer loss…
Provides a good overview of why proactive churn is important. But lacks accuracy in the details. Predictive model precision (not accuracy) shows if the model is "usable". Also, if we have 100 subscribers (50 churners and 50 "not churners") offering retention incentive to the 50 "not churners" can also make sense, because (1) it is sometimes not possible to identify customer's plans to churn (hard from conversation, impossible if sending SMS/email) and (2) mistargeting is often outweigh by correctly targeted.
