## Framework implementation

## Product feedback use cases

- [Understand why users leave onboarding unfinished](https://userreason.com/use-cases/onboarding-feedback/index.md): Ask a neutral question when someone explicitly pauses onboarding. Use a conditional follow-up, minimal event context and careful interpretation of saved answers.

- [Ask for feedback after cancellation is scheduled](https://userreason.com/use-cases/cancellation-surveys/index.md): Offer optional cancellation feedback after scheduling is confirmed. Use neutral questions, a conditional follow-up and careful interpretation of reported reasons.
