Generative AI for Enterprise: The Practical Guide to Moving from Pilot to Production

78% of enterprise GenAI pilots fail to reach production. This 58-page practitioner guide covers everything that the vendor briefings and analyst reports leave out: how to evaluate LLMs without being played by benchmark theater, how to build RAG architectures that stay accurate at scale, and how to design the governance and prompt engineering frameworks that allow regulated enterprises to deploy GenAI responsibly.

What You'll Learn
The LLM evaluation framework that bypasses benchmark theater and tests models on your actual use cases, data domains, and performance requirements, including the 8-dimension scorecard used across 40+ enterprise LLM selection engagements.
RAG architecture design decisions at enterprise scale, covering chunking strategies, vector database selection, retrieval quality tuning, and the hybrid search patterns that maintain accuracy as document corpora grow beyond 1 million items.
Hallucination mitigation and output quality assurance for production environments, including confidence scoring approaches, citation-anchoring patterns, and the human-in-the-loop designs that allow regulated industries to deploy GenAI while maintaining acceptable error rates.
The GenAI governance framework for regulated industries, covering prompt engineering governance, output logging requirements, bias testing for generated content, EU AI Act risk classification, and the model card standards expected in financial services and healthcare.
Fine-tuning vs. RAG vs. prompt engineering decision framework, with honest cost-benefit analysis for each adaptation strategy across common enterprise use case types, and the architecture decision tree for selecting the right approach given your constraints.
Proven GenAI use cases by industry sector, with implementation patterns from financial services, healthcare, legal, manufacturing, and professional services deployments, including the mistake patterns that caused failures and the design choices that led to production success.

01
Why 78% of GenAI Pilots Stall
The eight failure patterns behind GenAI pilot stagnation, drawn from post-mortem analysis of 60+ failed GenAI programs. Covers the governance vacuum pattern, the benchmark theater trap, the hallucination underestimation problem, and the organizational adoption failure mode that accounts for 40% of stalled deployments where the technical work was actually fine.
02
LLM Evaluation and Selection
How to evaluate GPT-4o, Claude, Gemini, Llama, Mistral, and specialized vertical models for your specific use cases without being misled by published benchmarks that are not representative of enterprise tasks. Includes the domain-specific evaluation design process, TCO comparison methodology, and the data residency and security review checklist for enterprise procurement.
03
RAG Architecture at Enterprise Scale
End-to-end RAG design for enterprise knowledge bases with tens of millions of documents. Covers chunking strategies by content type, vector database selection across Pinecone, Weaviate, pgvector, and Chroma, hybrid BM25 plus vector search, re-ranking, and the metadata filtering patterns that maintain retrieval precision as corpora scale beyond 1M items.
04
Hallucination Mitigation and Output Quality
Production-grade approaches to output quality assurance including confidence scoring, citation anchoring, output verification against source documents, and the human-in-the-loop workflow designs that meet the error rate requirements of financial services and healthcare use cases. Includes the output quality KPI framework used in production monitoring dashboards.
05
Fine-Tuning vs. RAG vs. Prompt Engineering
The decision framework for choosing the right LLM adaptation strategy given your use case requirements, available training data, latency constraints, and total cost of ownership tolerance. Covers when fine-tuning creates durable competitive advantage vs. when it creates ongoing maintenance burden, and the hybrid architectures that combine strategies effectively.
06
GenAI Governance for Regulated Industries
The governance architecture required to deploy GenAI in financial services, healthcare, legal, and insurance environments. Covers EU AI Act risk classification, prompt logging and audit trail requirements, bias testing methodologies for generated outputs, SR 11-7 applicability to LLM-based decision support, and the board-level reporting format for GenAI risk oversight.
07
Proven Use Cases and Implementation Patterns
Detailed implementation patterns from 25+ production GenAI deployments across five industries. Covers document intelligence in legal, clinical documentation in healthcare, regulatory change monitoring in financial services, technical knowledge bases in manufacturing, and client communication in professional services. Each pattern includes architecture diagram, success metrics, and lessons from failed variants.
