Metrics question
What north-star and guardrail metrics would you use to judge whether Lovable’s identity platform is working for both builders configuring access and application users signing in? Include metrics for setup success, sign-in reliability, authorization correctness, enterprise adoption, and support burden, and explain how metric movement would change your roadmap.

What this question tests
Tests building a two-sided metrics framework, builder and end user, for an identity platform, and tying metric movement to roadmap decisions.
How to approach it
- Separate the two audiences: builders configuring access and application users signing in, since their success looks different.
- For builders, track setup success: time to first working integration, percent of configurations completed without a support ticket.
- For end users, track sign-in reliability: auth success rate, median login latency, failed-login recovery rate.
- Set an authorization-correctness guardrail: rate of over- or under-permissioned sessions, since this breaks trust, not just UX.
- Track enterprise adoption and support burden: percent of workspaces on SSO/SCIM, identity tickets per active workspace.
- Tie thresholds to action, for example a rising auth-error guardrail halts new features in favor of a reliability sprint.
What a strong answer includes
- Picks one clear north-star per audience, time-to-first-login for builders and auth success rate for users, rather than a long list.
- Treats authorization correctness as a hard guardrail, not a normal KPI, with an illustrative threshold like under 0.1 percent error.
- Connects metric movement to explicit roadmap consequences, not dashboards nobody acts on.
Common mistakes
- One undifferentiated metrics list instead of separating builder and end-user success.
- No guardrail for authorization correctness, the highest-risk failure mode here.
Likely follow-up questions
- What would you do if setup completion rose but tickets also rose?
- How would this framework change for a regulated enterprise customer?
