RAG and retrieval quality guide

How retrieval relevance, coverage and grounding affect answer quality.

Step 1

Create retrieval ground truth

Write down the user, decision and unacceptable failure before choosing a metric. This prevents a polished demo from becoming the evaluation standard.

Treat missing evidence as an explicit state. A result should explain what supports it, how confident the team can be and what to collect next.

Step 2

Measure relevance and coverage

Use representative evidence and keep the tested provider, model, operation, account, region and time window attached to every conclusion.

Step 3

Inspect grounded answers

Use representative evidence and keep the tested provider, model, operation, account, region and time window attached to every conclusion.

Treat missing evidence as an explicit state. A result should explain what supports it, how confident the team can be and what to collect next.

Step 4

Track failure categories

Use representative evidence and keep the tested provider, model, operation, account, region and time window attached to every conclusion.

Treat missing evidence as an explicit state. A result should explain what supports it, how confident the team can be and what to collect next.

Turn the framework into one representative evaluation.

Use a starter template or request a reviewed benchmark. Do not send credentials or confidential production data through a public form.
