Net Promoter Score (NPS)
A metric that measures customer loyalty based on the likelihood of recommending a product on a 0–10 scale.
NPS asks a single question — "How likely are you to recommend us to a colleague?" — on a 0–10 scale, then classifies responses into Promoters (9–10), Passives (7–8), and Detractors (0–6). The score is Promoters minus Detractors as a percentage of respondents, producing a number from −100 to +100. A free-text follow-up captures the reason, which is usually the more valuable half of the data.
NPS has well-known limitations: it is sensitive to when you ask, who you ask, and cultural response bias. On its own it is a vanity number. Useful NPS programs track the score as a trend over time, segment it by persona and lifecycle stage, and actually close the loop with detractors and passives. The qualitative comments are where the real signal lives.
为何重要
Used well, NPS is a cheap, continuous pulse on customer sentiment. Used poorly, it becomes a meaningless board slide.
