Unlocking New Career Paths: How RAG Skills Can Empower Technical Communicators

Number 20 in our series on skills for modern technical communicators

Remember when technical documentation was just about writing clear instructions? Those days are disappearing as artificial intelligence transforms our profession. This week, we’re exploring a technology that’s becoming a key skill for modern technical communicators: Retrieval-Augmented Generation, or RAG.

Let me introduce RAG with a little poem, as has become our tradition in this series:

In knowledge’s vast domain we dwell,
Where data depths and stories swell,
Through RAG we bridge the old and new,
Weaving context, fresh and true.

Understanding RAG

RAG (Retrieval-Augmented Generation) represents a fundamental shift in how AI systems access and use information. Unlike traditional Large Language Models (LLMs) that rely solely on their training data, RAG systems actively retrieve relevant information from specific knowledge bases before generating responses.

How RAG Works

Understanding how RAG works in practice helps technical communicators leverage it effectively. Let’s break down the process into its key components and explore how they function in real-world documentation scenarios.

The Retrieval Process

The magic of RAG begins with effective retrieval. When documentation is prepared for RAG systems, it undergoes several crucial steps:

1. Chunking
   
   Documentation is divided into meaningful segments that preserve context while remaining specific enough to be useful. These might be paragraphs, sections, or even entire pages, depending on your content structure.
   
2. Embedding Creation
   
   Each chunk is transformed into a mathematical representation—an embedding—that captures its semantic meaning. Think of these as sophisticated fingerprints that identify not just what the content says, but what it means.
   
3. Vector Storage
   
   These embeddings are stored in specialised vector databases, which are optimised for finding similar content quickly. Unlike traditional databases that excel at exact matches, vector databases can find content based on meaning and context.

Integration with LLMs

When a user poses a question, RAG systems perform a sophisticated dance between retrieval and generation:

1. Query Processing
   
   The user’s question is converted into the same type of embedding as your stored documentation.
   
2. Semantic Search
   
   The system searches for relevant content by comparing the question’s embedding with your documentation embeddings.
   
3. Context Assembly
   
   The most relevant chunks are gathered and formatted into a context window that the LLM can use.
   
4. Response Generation
   
   The LLM generates a response using both its training and the retrieved context, ensuring accuracy and relevance.

Vector Databases and Embeddings

Vector databases form the backbone of effective RAG systems, offering several key advantages:

• Semantic Understanding
  
  They can find relevant content even when exact keywords don’t match
  
• Scalability
  
  They handle large documentation sets efficiently
  
• Speed
  
  They retrieve relevant information quickly enough for real-time responses
  
• Accuracy
  
  They maintain relationships between related pieces of content

Context Window Optimisation

Managing context windows—the amount of retrieved information fed to the LLM—requires careful balance:

• Too little context: Responses lack depth and accuracy
  
• Too much context: Responses become unfocused or hit token limits
  
• Just right: Responses are accurate, relevant, and concise

For technical communicators, optimising these windows means:

• Structuring documentation with clear boundaries
• Maintaining consistent levels of detail
• Creating logical content relationships
• Understanding how different content types affect context requirements

This technical foundation enables RAG to transform static documentation into dynamic knowledge resources, ready to answer user queries with accuracy and authority.

Now, let’s look at an example of RAG in action, using a real-world example, answering the question “What are the latest developments in AI for fighting climate change?”

The Technical Process in Action

1. Query Processing
   
   • The system analyses the question to identify key concepts (“AI,” “climate change,” “latest developments”)
     
   • The query is converted into a mathematical representation (embedding) to capture its meaning
     
2. Retrieval
   
   • The system searches a knowledge base of documents, each pre-processed into similar mathematical representations
     
   • Using vector similarity, it identifies the most relevant content
     
   • The top relevant documents or passages are selected
     
3. Augmentation and Generation
   
   • Selected content is combined with the original query
     
   • The LLM processes both the query and retrieved information
     
   • A response is generated using verified, up-to-date information

With this technical foundation in place, let’s examine how organisations are putting RAG to work in real-world documentation systems.

Applications and Use Cases

RAG’s practical applications in technical communication extend across multiple areas of our work. Here are the key ways technical communicators are using RAG to enhance their documentation systems:

Smart Documentation Systems

Modern documentation platforms powered by RAG offer:

How is RAG Useful for Technical Communicators?

RAG represents a watershed moment for technical communication, addressing one of our field’s most pressing challenges: maintaining accuracy and authority in an era of AI-driven content creation.

While traditional LLMs have shown remarkable capability in generating fluent text, they often struggle with technical accuracy and can produce content that’s convincingly written but factually incorrect.

RAG changes this dynamic by creating a bridge between two worlds: the creative, adaptable nature of AI language models and the structured, authoritative content that technical communicators have carefully crafted over years.

The merger of AI capability with verified technical content opens unprecedented opportunities for our field. We’re becoming architects of intelligent knowledge systems that serve both human readers and AI assistants.

Our expertise in organising and structuring technical information is becoming even more valuable as it forms the foundation for these AI-enhanced documentation systems.

Before diving into specific applications, let’s understand how RAG transforms our profession:

Enhanced Capabilities and Efficiency

Start where you’re comfortable – with documentation. Begin by examining your current projects through a RAG lens. How might your documentation need to change if it were being read by both humans and AI systems? This simple shift in perspective is your first step toward RAG expertise.

From there, build your knowledge systematically:

1. Master the Foundations
   
   Begin with structured writing techniques and basic AI concepts. Join online communities discussing AI in technical communication.
   
   Take a beginner-friendly course in machine learning fundamentals. The goal isn’t to become a data scientist, but to understand how AI systems process and generate text.
   
2. Dive into the Technical
   
   Once you’re comfortable with the basics, explore vector databases and embeddings. Start small – experiment with free tools and open-source RAG systems.
   
   Many technical communicators find that hands-on practice with these technologies demystifies their complexity.
   
3. Apply Your Knowledge
   
   Look for opportunities to implement RAG concepts in your current role. This might mean reorganising documentation for better chunking, creating metadata schemas, or designing content validation workflows. Each practical application deepens your understanding.
