Mastering Customer Feedback: Driving Business Growth through Customer Insights

A: A looks boring and that's why it's right. NPS lives and dies on the total response count, even when Passives feel like noise. B is the classic marketing slide error — it reports advocacy rate, not NPS. C feels engineering‑ish because it normalizes to a signal, but NPS never does that. D sounds like a quality escape argument, yet the standard definition doesn't let you edit the denominator just because you don't like what Passives say.

A: A accepts that the process changed, not the product. Lower participation skews toward vocal extremes or loyal users. B is tempting when dashboards go green, but you're locking in selection bias. C imports a validation logic from testing, ignoring that feedback isn't statistically controlled. D feels analytical, yet it doubles down on the same biased population and hides the missing voices.

A: A ties feedback to CAPA, which is the spine of ISO 9001. Without records, you can't close the loop or prove effectiveness. B sounds reasonable but benchmarking isn't mandated. C mixes in CMMI thinking; ISO audits verify system control, not maturity scoring. D may be true in boardrooms, yet ISO doesn't care about EBITDA, only controlled processes.

A: A explains why tests look fine while the field screams. You're blind to the population that actually fails. B could explain the noise, but not why it only appears in customer channels. C and D live in DFMEA land and fit vibration stories, yet they don't account for the clean internal data unless you're assuming a massive test escape.
