Published engineering methodApplied AI evaluation

Production RAG Validation Suite

A published evaluation method for testing retrieval quality, groundedness, and failure boundaries before a knowledge assistant is released.

  • Hybrid retrieval
  • Cross-encoder reranking
  • Groundedness evaluation

Question, contribution & scope
The question
A convincing demo answer does not establish retrieval quality or reliable handling of unsupported questions.
The approach
Evaluate chunking, hybrid retrieval, reranking, citations, and refusals against a representative question set.

A technical guide with a readiness checklist and a retrieval trade-off table.

Scope: A written methodology, not an implemented benchmark product or a published scored evaluation run.

Have a problem that does not fit a category?

Most real systems cross more than one discipline. Bring the constraint and we will map the smallest reliable path through it.
