WHAT IS NPS AND HOW IT IS MEASURED?
To calculate the customer loyalty index or NPS, we ask our customers to answer a question: Would you recommend our company to your colleagues and business partners on the scale from 0 to 10? Based on the scores, the customers’ responses are divided into three groups: “Promoters” are those who gave 9-10 points, “Neutrals” – 7–8 points. ose who gave the score below six points are included in the “Detractors” group. e diff erence between the share of “Promoters” and the share of “Detractors” is our Company’s net promoter score index. www.corum.com
