Field note: Retrieval-augmented generation can connect a language model to approved material at answer time. That can improve traceability and freshness, but it does not guarantee that the right passage was found, interpreted correctly, or treated as authoritative.
Operational question
Is the problem primarily missing knowledge, or is it actually ambiguous policy, inconsistent documents, poor information architecture, or a task that should remain deterministic?
A workable method
- Define the answerable corpus. Identify which documents are authoritative, who owns them, how versions are controlled, and what the system must do when sources conflict.
- Test retrieval separately. Before judging prose, check whether the correct passages appear for realistic queries. Missed retrieval and incorrect synthesis require different fixes.
- Design citations for verification. Link to a stable document location, show enough surrounding context, and avoid citations that merely point to a long document. Reviewers need to verify a claim quickly.
- Preserve a safe no-answer state. When evidence is absent, contradictory, or outside the approved corpus, the system should say so and route the user to an accountable source.
What this looks like in practice
A fleet learning assistant can retrieve an approved safety management procedure and identify the relevant section. It should not infer a vessel-specific limit from a generic manual or combine two conflicting revisions into a confident answer.
Evidence to collect
Choose a small set of measures before implementation. Record the baseline, the source of each measure, the review cadence, and who is authorized to act on the result.
- retrieval recall for known-answer cases
- citation correctness and verification time
- rate of unsupported answers when evidence is absent
Field checklist
- Write the decision, accountable owner, and decision date.
- Describe the current workflow and the conditions that shape performance.
- Confirm the source hierarchy, permissions, and local requirements.
- Test the method under representative—not merely convenient—conditions.
- Review both intended outcomes and burden on the people doing the work.
- Record a change, escalation, and stop rule before results arrive.
Watch-out
Better retrieval cannot compensate for an unmanaged document collection. Establish ownership, effective dates, supersession rules, and removal processes before presenting the corpus as a source of truth.
