User Friendly Net Promoter Score Based Recommender System for Boosting Business Revenue

Duration: Half day

Short Description: Popular industry standard for measuring customer satisfaction is called Net Promoter Score (NPS). It is computed as %Promoters -%Detractors, where percentage is understood as the total number of promoters/detractors divided by the total number of surveys. But, most executives would like to know not only the changes of that score, but also why the score moved up or down. More helpful and insightful is to look beyond the surface level of customer responses and dive into the entire anatomy of their feedback. Collected customers feedback includes not only simple score ratings (such 0-10 scale or start ratings) – these are also customers thoughts, feelings, expectations in free-form text. They convey specific messages, for example, that company’s service technician needs more training or invoices came in late and prices were higher than expected. This tutorial will present the entire process of building a user friendly NPS-based Recommender System for boosting business revenue taking into account a large variety of data collected by telephone surveys on customer satisfaction. The system has hierarchical structure and is driven by actionable knowledge hidden in customer surveys.
