AI & Technical question
Before launching a new AI workflow for a high-volume support use case, what quality bar would you set? Define the offline and online eval framework, launch criteria, and post-launch monitors you would use to measure task success, reliability, safety and groundedness, latency, fallback behavior, and customer trust at scale.

What this question tests
Tests defining a rigorous pre-launch quality bar for a high-volume AI workflow, spanning offline evals, launch criteria, and post-launch monitoring.
How to approach it
- Build an offline eval set covering task success on representative real conversations, including edge cases like ambiguous requests and adversarial inputs.
- Define offline thresholds for safety and groundedness specifically, not just task success, since a fluent but ungrounded or unsafe answer can pass a naive accuracy check.
- Set launch criteria combining offline eval scores with a limited online pilot, comparing task success, latency, and fallback rate against the human-handled baseline.
- Define fallback behavior explicitly as part of the launch bar: the workflow must gracefully hand off on low-confidence cases, not guess.
- Set post-launch monitors: real-time task-success sampling, latency percentiles, and a safety-incident flag reviewed daily during the first weeks.
- Set a rollback trigger tied to specific thresholds, for example safety-flag rate above a set level, so the response to degradation is pre-decided, not improvised.
What a strong answer includes
- Separates safety and groundedness thresholds from task-success accuracy, since a workflow can look accurate while still being ungrounded or unsafe.
- Requires an online pilot comparison against the human baseline before full launch, not offline evals alone.
- Pre-defines a rollback trigger with a specific threshold, avoiding improvised decisions during a live incident.
Common mistakes
- Relying on offline evals alone without an online pilot comparison.
- No pre-defined rollback trigger, leaving the response to a live degradation improvised.
Likely follow-up questions
- How would you sample conversations for daily monitoring at high volume?
- What would you do if offline evals passed but the online pilot showed a latency regression?
