NPS Is a Vanity Metric

Net Promoter Score (NPS) became the default B2B customer metric because it is simple to ask and easy to put on a slide. It is also one of the least-useful inputs to actual product, marketing, or customer success decisions. The single number hides the underlying signal, and the trend line is noisy enough that quarter-over-quarter changes are usually not meaningful.

What to use instead: Customer Effort Score (CES), which asks 'how easy was it to accomplish what you came to do.' CES is more directly tied to retention behavior, easier to act on (low scores point at specific friction), and less noisy than NPS. Pair CES with open-text follow-ups for diagnostic value.

If you must use NPS for board reporting (because the board expects it), keep it but stop letting it drive decisions. The decisions should come from CES, churn rate, expansion rate, and direct customer interviews. NPS becomes a vanity number for the deck, not a strategic input.

The teams that get the most value from customer feedback do three things: ask CES on every meaningful product interaction (not just annually), read every open-text response (yes, every one), and produce a quarterly report of the top 5 friction patterns with proposed fixes. This produces decision-quality data. NPS does not.
