RAG Product Strategy

Overview

RAG adds a retrieval step before LLM generation to ground outputs in current, domain-specific content. This high-leverage pattern reduces hallucinations, enables domain customization without expensive fine-tuning and connects products to enterprise knowledge stores.

Best for: Knowledge-heavy apps (support, legal, research) where provenance and accuracy matter.

Key decisions: Index design, vector store selection, retrieval strategy, citation UX and operational trade-offs (latency, cost, freshness).

When to Choose RAG

Use RAG when:

  • Data changes frequently (docs, policies, market data)
  • You need answer traceability and source citations
  • You want faster iteration than model retraining
  • Private knowledge must stay out of training data

Expected outcomes: Lower hallucination rates, faster domain feature delivery

Example: Support assistant retrieves product manuals and incident reports, then creates troubleshooting plans with direct citations.

Core Trade-offs

Recall vs. Precision

  • High recall: Broad context but more noise
  • High precision: Quality context but may miss relevant info
  • Tune: k (retrieved docs) and filtering by use case

Latency vs. Freshness

  • Sync retrieval: Fresh data, higher latency
  • Async/cached: Lower latency, potentially stale data

Provenance UX

  • Always show sources transparently
  • Enable "show source" and direct doc links
  • Legal use case: k=2-4, inline citations with paragraph numbers
  • Brainstorming use case: k=8-20, looser citation requirements

Success Metrics

Model Performance

  • Accuracy/Hallucination rate (human-evaluated sample)
  • Source trust rate (% users clicking source links)

Product Impact

  • Task completion rate with RAG vs. baseline
  • Time-to-resolution improvement
  • Cost per query (retrieval + embedding + LLM tokens)

Business Outcomes

  • User trust scores
  • Reduced escalations
  • Lower SME manual workload

Implementation Roadmap

Week 1-2: Pilot

  • Pick 1 high-impact workflow (support KB)
  • Build minimal pipeline: crawler → embeddings → vector store → retriever → LLM

Week 3-4: Measure

  • Add telemetry: query latencies, top-k precision, user source clicks
  • Set up human verification for edge cases

Week 5-8: Optimize

  • Tune embedding model, similarity metrics, k values
  • Add re-ranker models if needed
  • Feed errors back into filters and prompts

Scale Phase:

  • Production-grade vector DB with persistence, replication, autoscaling
  • Multi-format ingestion: tables, PDFs, images

Decision Framework

Dynamic Data? → RAG Need Provenance? → RAG + Citations Small Static Dataset? → Fine-tune Strict <300ms Latency? → Prompting/Distilled Model

Configuration by Use Case

Legal: 2-4 docs, strict filters, inline citations, low latency tolerance

Support: 3-6 docs, metadata filters, expandable links, medium latency tolerance

Research: 8-20 docs, light filters, source lists, high latency tolerance

Avoid These Mistakes

  • Raw text dumps: Leads to prompt bloat and token waste
  • No metadata filters: Returns irrelevant docs without source-type, date, author filters
  • Silver bullet thinking: RAG reduces but doesn't eliminate hallucinations

Key Takeaways

  1. Dynamic data = RAG: Index updates beat model retraining for changing content
  2. Provenance first: Always show sources for enterprise trust
  3. Intent-based config: High-precision for legal, high-recall for discovery
