Problem
Scenario
You've shipped a new product feature and need a clean way to evaluate whether it is working. The team wants one primary success metric, but also wants supporting metrics that capture early user response and protect against harmful side effects.
Question
How would you choose the primary metric and guardrail metrics for a new feature launch?
What matters
- Pick one primary metric that reflects the feature's core user value
- Separate leading indicators from lagging indicators
- Add guardrails that protect user experience and marketplace health
- Avoid vanity metrics that move without real business impact
