Success Measures Measure Expected Outcome Search relevance Improved judged relevance for priority queries without unacceptable latency or regression. Conversational quality Users complete multi-turn journeys with retained context and evidence-backed responses. Trust and safety Answers use approved sources, include citations, are monitored, and are suppressed when confidence is inadequate. Customer outcomes Reduced zero-result, reformulation, and abandonment rates; improved click-through and task completion. Operational readiness Pipelines, integrations, and model dependencies are observable, supportable, documented, and recoverable.
