The Net Promoter Score (NPS) is a tool that measures customer loyalty.
The outcome of the NPS is based on this fixed question: “How likely is it that you would recommend Company x (or Product X) to a friend or colleague?” You can answer on a scale range going from 1 to 10; with 10 being extremely likely to recommend. Once you’ve accumulated the results of the Net Promotor Score, you seperate the participants into three groups: Promotors (10 or 9), Passives (8-7), Detractors (6-1).
