Direct answer

A useful RAG scorecard records source availability, retrieval recall and precision, evidence coverage, answer faithfulness, answer relevance, citation validity, permission correctness, latency and cost for a versioned set of questions. It also captures failure categories and configuration.

Operational measures

  • Time to first and final result.
  • Retrieval, reranking and generation latency.
  • Input/output tokens and tool calls.
  • Empty-result and refusal rate.
  • Cost per successful task.
  • Human correction required.

Record success and efficiency together. Lower cost is not improvement if users repeat the question.

Failure taxonomy and gate

Tag missing source, parse error, stale index, permission error, query mismatch, ranking error, insufficient context, unsupported generation, invalid citation or UI failure. Compare slices, not only averages.

Define release gates in advance—for example zero cross-tenant disclosures and no regression in critical recall. The method is in evaluating RAG retrieval.
