## Edge Case Considerations
### When Baseline Data is Unavailable:

- Plan rapid baseline establishment after launch
- Use proxy metrics until direct measurement is possible
- Document assumptions and validation plans
### When User Privacy Limits Measurement:
- Focus on aggregate and anonymized metrics
- Use privacy-preserving measurement techniques
- Balance measurement needs with privacy requirements
