01How would you create an enterprise strategy for SRE principles across business units?
A principal-level answer
Say this first: SRE principles should be explained through its purpose, the boundary where it applies, and the evidence that shows it is working.
Use a real scenario
Imagine a customer-facing API that must survive a regional dependency failure. The team must decide how to apply SRE principles, verify the result, and explain the user impact. For a Site Reliability Engineer, attach the explanation to a runbook and recovery test result.
Show judgment
- set decision rights, investment thresholds, and risk-based governance without centralizing every choice.
- State the constraint that could change your decision, such as scale, data sensitivity, recovery target, or team ownership.
- Call out a broad outage or an untested recovery path and the control that reduces it.
Evidence to mention
Track availability, recovery time, and cost per request. Say what baseline you compared against, what would trigger a rollback or escalation, and who owns the follow-up.
