  • RAG quality depends on the evidence path: source selection, access control, parsing, chunking, retrieval, citation, evaluation, and freshness. A vector index is one component of that path.

Name the decision criteria

Choose between behavior adaptation and retrieved evidence by examining knowledge freshness, provenance, evaluation, privacy, and operating responsibility. RAG quality depends on the evidence path: source selection, access control, parsing, chunking, retrieval, citation, evaluation, and freshness. A vector index is one component of that path. For fine-tuning versus RAG for enterprise systems, the first useful artifact is a bounded statement of the consumer outcome, the current dependency, and the decision owned by ai platform lead.

What must be explicit

Start with the two inputs shown in the decision aid: Focus: RAG and Audience: ai platform lead. Then identify the system that remains authoritative, the consumer that relies on the result, and the exception that would make the design unsafe or misleading.

The expected scope output is A bounded problem and named owner. That output is specific enough for an owner to accept or reject. It also prevents RAG from becoming a label for unrelated work.

Compare the operating boundaries

RAG quality depends on the evidence path: source selection, access control, parsing, chunking, retrieval, citation, evaluation, and freshness. A vector index is one component of that path. Data quality becomes actionable when a consumer can see ownership, freshness, provenance, conflict policy, and known gaps. A copied record with no qualification often moves the uncertainty rather than resolving it. The boundary for this review is AI agent infrastructure, with data quality treated as the change under evaluation.

Review point What to record for RAG
Consumer promise The fields, operation, freshness, and failure behavior the consumer can rely on
Source authority The system responsible for each material value or action
Qualification The limits, provenance, policy, and exceptions that must remain visible
Change control The owner, version rule, test evidence, and consumer notification path

A diagram is useful only when it makes these decisions inspectable. For fine-tuning versus RAG for enterprise systems, reviewers should be able to follow a request from the consumer boundary to each dependency and back to the qualified result.

Record the tradeoff

The design is incomplete until a team owns access, change, failures, review evidence, and retirement. Agents need bounded context and actions. Model access, enterprise data access, and business operations are separate boundaries that should be governed and observed together. Assign the operating decision to data leader and use review-annually as the review condition captured in the article scenario.

In the review for Fine-tuning versus RAG for enterprise systems, the decision record should name access ownership, monitoring evidence, failure handling, and the retirement path. If one team owns the consumer contract while another owns a source dependency, the handoff and escalation path need to be written down. This matters most when the decision spans more than one system or consumer.

Questions for the design review

  • Which consumer outcome makes RAG worth standardizing or governing?

  • What material source difference would be hidden by the proposed AI agent infrastructure boundary?

  • Which evidence lets data leader distinguish a contract failure from a source failure?

  • When data quality changes again, which consumers should remain insulated and which must be notified?

  • What condition would cause the team to reject this approach and choose a narrower design?

For Fine-tuning versus RAG for enterprise systems, a useful review can end with a qualified no. The aim is to make the decision, dependency, and ownership clear enough that another team can understand what was chosen and why.
