Use case
Short answer
Build an internal answer layer on your docs, not a generic chatbot. Enforce permissions at retrieval time and require citations for important claims. If confidence is low, return “no answer” and escalate. Fine-tune only when retrieval, prompting, and policy still cannot deliver the behavior you need.

| Criterion | Recommended when | Use caution when |
|---|---|---|
Your knowledge sources are real systems of record (not scattered PDFs and tribal Slack threads) with named owners. | Teams are burning time re-answering the same questions (runbooks, policies, system behavior, account history). | Your docs are stale, politically disputed, or lack owners, so retrieval just scales confusion. |
You can map and enforce access controls at retrieval time (role/team/project ACLs), not just in the UI. | Search returns documents, but the real need is decision-ready synthesis with citations. | You cannot enforce access controls on retrieved content (risk of leaking private or regulated material). |
Users need answers with provenance (citations/quotes) so they can verify and correct quickly. | You can start with one domain (e.g., incident response, support policy, finance close) and expand via gates. | You need legal-grade guarantees on every answer but are unwilling to invest in human review lanes. |
You can collect query logs and outcomes (clicked citations, escalations, “answer was wrong”) to drive evals. | Your organization needs traceability: who answered what, with which sources, under which policy. | You want a “chatbot” for optics rather than an operational system with eval gates and telemetry. |
You can build and maintain ingestion (connectors, chunking, dedupe, freshness) as a product, not a one-off. | You can operate a weekly cadence for evals, content fixes, and retrieval/policy updates. | You cannot budget ongoing maintenance (ingestion, evals, governance); RAG quality decays without it. |
Security can approve a threat model for prompt injection, data leakage, and tool-use boundaries (OWASP-aligned). | Teams are burning time re-answering the same questions (runbooks, policies, system behavior, account history). | Your docs are stale, politically disputed, or lack owners, so retrieval just scales confusion. |
Phase 1
Baseline the current workflow, metrics, and risk thresholds.
Phase 2
Run a constrained pilot with explicit quality and governance gates.
Phase 3
Scale only after evidence confirms reliability, cost, and adoption targets.

After
Federal Reserve Bank of St. Louis analysis reports average time savings of 5.4% of work hours among GenAI users and estimates a 1.1% aggregate labor-productivity effect.
Evidence lens
AI copilots can materially raise operational throughput in real workflows.
National Bureau of Economic Research • 2023-11 (revision) • working paper
Metric context
+14% issues resolved per hour with AI assistant access (study of 5,179 support agents).
Caveat
Single-company context; validate lift against your own knowledge workflow distribution.
Reported GenAI usage suggests meaningful time savings among current users.
Federal Reserve Bank of St. Louis • 2025-02-03 • gov publication
Metric context
Average time savings equal to 5.4% of work hours among users.
Caveat
Self-reported time savings; not a controlled enterprise-knowledge experiment.
GenAI adoption levels map to non-trivial aggregate productivity upside.
Federal Reserve Bank of St. Louis • 2025-02-03 • gov publication
Metric context
Estimated +1.1% aggregate labor productivity effect; +33% productivity on genAI-assisted hours.
Caveat
Modeled macro estimate; treat as directional, not a direct enterprise KPI.
There is already a formal GenAI governance profile to anchor enterprise controls.
National Institute of Standards and Technology • 2024-07-26 • gov publication
Metric context
NIST GenAI profile published as NIST AI 600-1 on 2024-07-26.
Caveat
Framework publication confirms control baseline, not operating performance improvement.
Enterprise AI governance should cover full lifecycle functions, not just output quality.
National Institute of Standards and Technology • 2023-01-26 (updated 2025-02-03) • gov publication
Metric context
AI RMF defines 4 functions: Govern, Map, Measure, Manage.
Caveat
Process guidance informs governance design; outcomes still depend on local execution quality.
A minimum security baseline for RAG systems should map to OWASP’s LLM risk taxonomy.
OWASP Foundation • 2025 • industry survey
Metric context
OWASP Top 10 for LLM Applications (v1.1).
Caveat
Risk taxonomy supports threat coverage, but does not quantify incident rates.
Your docs are stale, politically disputed, or lack owners, so retrieval just scales confusion.
Why: noisy labels break evaluation and calibration, so threshold tuning turns into politics instead of telemetry.
You cannot enforce access controls on retrieved content (risk of leaking private or regulated material).
Why: this usually signals governance, ownership, or data-readiness gaps that increase misroute risk.
You need legal-grade guarantees on every answer but are unwilling to invest in human review lanes.
Why: this usually signals governance, ownership, or data-readiness gaps that increase misroute risk.
You want a “chatbot” for optics rather than an operational system with eval gates and telemetry.
Why: this usually signals governance, ownership, or data-readiness gaps that increase misroute risk.
You cannot budget ongoing maintenance (ingestion, evals, governance); RAG quality decays without it.
Why: triage is a service; without a weekly ops cadence, drift and misroutes quietly accumulate.
Is this just a chatbot on top of Confluence?
No.
A knowledge answer layer is a governed system: identity-aware retrieval, citation requirements, evaluation gates, and an explicit “no answer” path when grounding is weak.
How do we prevent confidential data leakage through retrieval?
Enforce ACLs at retrieval time, not only in the UI.
Log every retrieved chunk and citation, and run red-team tests for prompt injection and data exfiltration.
What is the minimum evaluation needed before broad rollout?
A fixed eval set per intent with grounding checks, permission checks, refusal quality, and regression tests on retrieval changes.
If you cannot measure faithfulness, do not scale.
When should we fine-tune instead of relying on RAG?
Fine-tune when you have stable labels and the product requirement is consistent output structure or behavior that better context cannot solve.
For evolving knowledge domains, start with retrieval for freshness and traceability.
How do we keep citations from becoming “fake rigor”?
Measure citation faithfulness.
Require quotes or snippet previews for critical claims, sample answers weekly, and treat unfaithful citations as a gating failure that blocks expansion.
