# Diagnose Why a Newly Launched Feature Has Almost No Users
A newly launched feature has almost no usage. Explain how you would diagnose the problem before proposing changes. Consider exposure, entry points, user understanding, product friction, and targeting, and show how you would distinguish a discovery problem from a weak value proposition.
### What a Strong Answer Covers
- Validation of the usage measure and eligible-user population.
- A funnel from eligibility and exposure through discovery, attempt, completion, and repeat use.
- Evidence-driven segmentation and investigation of comprehension, friction, and relevance.
- Targeted interventions and evaluation that avoid equating more exposure with more value.

A user cannot reject a feature they never saw, but seeing it does not establish that they understood it.
```
### Follow-up Questions
- What does high first-use but almost no repeat-use suggest?
- When would improving the entry point be a poor response?
Overview: Diagnose low feature adoption through eligibility, exposure, discovery, comprehension, friction, targeting, and repeat-use evidence.
