To show the growing importance of RAG solutions, Databricks, a global data and AI analytics company, reports that 60% of their LLMs use RAG. The high potential of this technology, given the high popularity of AI in general, is what makes it worthy of good consideration on a business level. 

Currently, AI-driven solutions are of huge popularity across businesses and industries. Retrieval Augmented Generation (RAG) is exactly the technology that offers better AI performance, whether it’s a common chatbot or an enterprise-level data analytics solution.

In this post, you’ll discover the common enterprise RAG system implementation strategy, its architecture pattern, key concepts, and related considerations. Besides, you’ll obtain an overview of the 10 best practices for utilizing and integrating RAG systems in enterprises. 

Common architecture pattern of RAG systems for enterprise

RAG systems are AI models that combine information retrieval and text generation to provide more accurate and contextually relevant responses. 

RAG systems are often employed in Large Language Model (LLM) solutions, like ones based on ChatGPT or Claude AI where they aid in retrieving relevant information from large datasets or documents needed for handling complex queries. In tasks requiring up-to-date or domain-specific knowledge, such as customer support, research, and enterprise applications, RAG systems offer unmatched response accuracy improvement. 

The RAG technique is well-suited for Natural Language Processing (NLP) applications, as it combines retrieval-based methods with generation-based models. It allows for effectively harnessing the strengths of both approaches.

Different embedding models can yield varying results. Some models might capture the overall style or intent of a question, while others may focus on individual words rather than the actual meaning. Experimenting with multiple embedding models is beneficial to identify which best aligns with your intended results.

The infographics depicting a common RAG architecture pattern is shown below:

Basically, what the demonstrated architecture of the advanced Retrieval Augmented Generation model reveals is that RAG handles user queries with enhanced security, retrieval, and response generation processes. Starting from user input, it follows steps including authentication, input guardrails, and query rewriting. It utilizes components like encoders, retrieval systems, and ranking to refine information from stored data (embedding, document, history, and feedback storage). 

This architecture pattern can be broken down into these RAG workflow steps:

1. User input and authentication
2. Input validation with guardrails
3. Query rewriting and encoding
4. Information retrieval from storage
5. Ranking and response generation
6. Output validation with guardrails
7. Final response delivery to the user

10 best practices for using Retrieval Augmented Generation (RAG)

Let’s have an in-depth insight into the best practices for RAG system implementation, based on real practical experience of engineers from Intelliarts:

#1 Provide context on how the output was generated

In enterprise RAG systems, providing context around generated outputs is essential for building user trust and transparency. By offering users insight into the sources of information, they can verify data accuracy, which is especially valuable in sensitive areas like compliance or customer support. Intelliarts often integrates source attribution in RAG solutions, allowing users to track data origins in real time, enhancing credibility and confidence in the system.

#2 Feed the LLM product integration data

Integrating data directly from enterprise tools like CRM or ERP systems is crucial for RAG systems to provide contextually relevant and accurate responses. This integration allows the RAG system to deliver responses tailored to the business’s unique needs. Intelliarts regularly incorporates data from internal systems, ensuring real-time insights and improved response relevancy, which is especially beneficial in customer support and operations management.

#3 Continuously evaluate the outputs to spot issues and areas of improvement

To maintain optimal performance, RAG systems should undergo regular evaluations, focusing on consistency, load handling, and edge cases. This approach ensures that potential issues are quickly identified and addressed. At Intelliarts, we apply rigorous testing methods in all custom RAG implementations, allowing us to refine systems continuously and uphold performance standards, even under varying operational conditions.

#4 Utilize dynamic data loading/updating

Dynamic data loading ensures that RAG systems operate with the latest information, preventing outdated data from affecting response accuracy. This capability is crucial in fast-paced sectors where information constantly changes. Intelliarts integrates real-time data loading into RAG systems, allowing users to interact with the most up-to-date insights, which enhances response quality in areas like finance and customer support.

#5 Maintain hierarchical document structure

Keeping a hierarchical structure in documents enhances RAG systems’ ability to retrieve relevant information accurately. Organizing content with clear headings and subheadings ensures that retrieval focuses on contextually appropriate sections. This structure not only boosts response accuracy but also enables more meaningful, layered responses, especially important for industries dealing with complex data.

#6 Implement a thoughtful chunking strategy

Chunking documents into smaller parts improves retrieval efficiency but can create challenges if relevant information is split across chunks. To optimize chunking, use document structures like sections or paragraphs and experiment with an embedding-based strategy, like chunk size or overlapping, to balance information granularity and processing efficiency, thus enhancing RAG performance.

#7 Optimize retrieval quality with relevance scoring

Relevance scoring prioritizes the most applicable data during retrieval, improving the precision of responses. By aligning retrieved data closely with user queries, RAG systems deliver more contextually accurate answers. Intelliarts employs relevance scoring in enterprise RAG solutions like retrieval-based chatbots, especially for applications requiring precise data interpretation, such as regulatory compliance and financial analysis.

#8 Establish feedback loops for continuous learning

Feedback loops enable RAG systems to adapt over time, learning from user interactions to enhance response quality and accuracy. This continuous learning approach is key to meeting evolving business needs. Intelliarts integrates user feedback into RAG systems, refining data retrieval accuracy based on real-world usage, which is particularly beneficial in applications with dynamic requirements like customer service.

#9 Use version control for data sources and models

Version control is critical in RAG systems to manage changes to data sources and model configurations, especially in industries requiring strict audit trails. Intelliarts incorporates version control into enterprise RAG solutions, allowing for consistent tracking and updates, which supports data integrity and compliance in sectors like finance and legal.

#10 Use ensemble techniques to reduce bias

Combining outputs from multiple models through ensemble techniques helps reduce variance, making the system more robust. Intelliarts employs this approach in enterprise RAG systems, ensuring balanced insights that are especially valuable in decision-making contexts. This technique supports unbiased results, crucial for sectors like human resources and customer support, where fair responses are essential.
