Follow a repeatable process to continually evaluate and improve your RAG application​

Stop building RAG systems that impress in demos but disappoint in production
Transform your retrieval from "good enough" to "mission-critical" in weeks, not months
Most RAG implementations get stuck in prototype purgatory. They work well for simple cases but fail on complex queries-leading to frustrated users, lost trust, and wasted engineering time. The difference between a prototype and a production-ready system isn't just better technology, it's a fundamentally different mindset.
The RAG Implementation Reality
What you're experiencing right now
Your RAG demo impressed stakeholders, but real users encounter hallucinations when they need accuracy most
Engineers spend countless hours tweaking prompts with minimal improvement
Colleagues report finding information manually that your system failed to retrieve
You keep making changes but have no way to measure if they're actually helping
Every improvement feels like guesswork instead of systematic progress
You're unsure which 10% of possible enhancements will deliver 90% of the value
What your RAG system could be
With the RAG Flywheel methodology, you'll build a system that
Retrieves the right information even for complex, ambiguous queries
Continuously improves with each user interaction
Provides clear metrics to demonstrate ROI to stakeholders
Allows your team to make data-driven decisions about improvements
Adapts to different content types with specialized capabilities
Creates value that compounds over time instead of degrading
What Makes This Course Different
Unlike courses that focus solely on technical implementation, this program gives you the systematic, data-driven approach used by companies to transform prototypes into production systems that deliver real business value
The Improvement Flywheel: Build synthetic evaluation data that identifies exactly what's failing in your system-even before you have users
Fine-tuning Framework: Create custom embedding models with minimal data (as few as 6,000 examples)
Feedback Acceleration: Design interfaces that collect 5x more high-quality feedback without annoying users
Segmentation System: Analyze user queries to identify which segments need specialized retrievers for 20-40% accuracy gains
Multimodal Architecture: Implement specialized indices for different content types (documents, images, tables)
Query Routing: Create a unified system that intelligently selects the right retriever for each query
The Complete RAG Implementation Framework
Week 1: Evaluation Systems
Build synthetic datasets that pinpoint RAG failures instead of relying on subjective assessments
BEFORE: "We need to make the AI better, but we don't know where to start."
AFTER: "We know exactly which query types are failing and by how much."
Week 2: Fine-tune Embeddings
Customize models for 20-40% accuracy gains with minimal examples
BEFORE: "Generic embeddings don't understand our domain terminology."
AFTER: "Our embedding models understand exactly what 'similar' means in our business context."
Week 3: Feedback Systems
Design interfaces that collect 5x more feedback without annoying users
BEFORE: "Users get frustrated waiting for responses and rarely tell us what's wrong."
AFTER: "Every interaction provides signals that strengthen our system."
Week 4: Query Segmentation
Identify high-impact improvements and prioritize engineering resources
BEFORE: "We don't know which features would deliver the most value."
AFTER: "We have a clear roadmap based on actual usage patterns and economic impact."
Week 5: Specialized Search
Build specialized indices for different content types that improve retrieval
BEFORE: "Our system struggles with anything beyond basic text documents."
AFTER: "We can retrieve information from tables, images, and complex documents with high precision."
Week 6: Query Routing
Implement intelligent routing that selects optimal retrievers automatically
BEFORE: "Different content requires different interfaces, creating a fragmented experience."
AFTER: "Users have a seamless experience while the system intelligently routes to specialized components."
