/ THE SHORT ANSWER

Key takeaways
  • 01Test retrieval separately from answer fluency.
  • 02Include conflicting, stale, absent, and permissioned cases.
  • 03Price the ongoing content and evaluation operation, not only the software.

/ dotSuper point of view

RAG quality is an operating property of sources, retrieval, permissions, evaluation, and ownership. A fluent demo can hide weakness in every one of those layers.
01Orient

What the evidence says

OWASP’s LLM application guidance highlights risks including prompt injection, sensitive-information disclosure, vector and embedding weaknesses, excessive agency, and unbounded consumption.

02Signal

A practical decision framework

It is designed to make the decision inspectable, not to imitate a platform ranking formula, certification checklist, or legal test.

  • Sources: provenance, versioning, deletion, freshness, and ownership.
  • Retrieval: relevance, coverage, conflict handling, and permission enforcement.
  • Generation: grounded answers, citations, refusal, and uncertainty.
  • Operations: evaluation set, monitoring, change control, cost, and support.

How to put it into practice

Include straightforward, multi-source, ambiguous, unanswerable, stale, and restricted questions, then score retrieval and final answers separately.

Ask the vendor to demonstrate an update, a permission change, a source deletion, a model change, and a rollback.

These lifecycle actions determine whether the system can be safely owned.

  • Name the accountable owner and the decision this work must enable.
  • Record the current evidence, assumptions, exclusions, and next review trigger.
  • Measure a useful outcome rather than treating publication or deployment as success.

What this page cannot conclude

  • 01A short acceptance set cannot predict every production interaction.
  • 02Sector-specific privacy, records, security, and residency requirements need separate review.
  • 03Publication, technical eligibility, or good practice cannot guarantee ranking, referral traffic, citation, adoption, or a business outcome.
