Activation Workshop-1

 

 

 

Activation Workshop

During this workshop, NOVA works with stakeholders to define a practical LLM or RAG use case and outline the system architecture needed to support it. Our team plans how data retrieval, prompts, and model responses should work together.

Participants also design the environment required to run the solution. The goal is to move from concept to a working proof of concept that shows how the system retrieves information and produces useful responses.

What’s Included:

  • Interactive workshop session (1-2 days)
    • Part 1: Use case scoping and solution concept
    • Part 2: Architecture planning and prototype setup
  • Design of an operational AI environment
  • Integration of models, prompts, or retrieval logic
  • Development and demonstration of a working proof of concept

Production Workshop

This workshop focuses on turning a successful proof of concept into a system your organization can operate and scale. We'll work with your team to define architecture, infrastructure needs, and deployment steps for a custom LLM or RAG solution.

Our discussion covers system reliability, expected workloads, and how the AI service will interact with existing platforms. The outcome is a practical roadmap that shows how to move from testing to a production-ready system.

What’s Included:

  • One-day production planning workshop
  • Implementation steps for launch
  • Recommended implementation model
  • Defined project scope
  • Estimated implementation costs

n1-1

 

How do organizations decide if they need a custom LLM or a standard AI tool?

Many companies start with general AI tools, but those tools typically have limited access to internal knowledge or specialized workflows. Custom LLM Development becomes useful when teams need systems built around their own knowledge sources, internal processes, and decision logic.

Instead of generic responses, large language models can be tailored to support real operations like internal search, knowledge management, or automated task support inside business applications.

What types of business data can be used in a RAG system?

A Retrieval-Augmented Generation system works best when it connects to reliable internal information. These may include documents, product manuals, policies, support articles, CRM records, or structured databases.

A RAG pipeline retrieves the most relevant information before generating a response. This allows AI systems to answer questions using verified business content rather than relying only on general training data.

How do custom LLM systems help employees work faster?

Employees usually spend time searching through multiple tools to find answers. But an AI agent can retrieve information from company data and present it in a single response.

Techniques like prompt augmentation and prompt engineering guide the model so answers stay focused on the task. This reduces time spent searching for information and helps teams complete daily tasks faster.

Can RAG systems support multiple teams or departments?

Yes. A single AI system can support different teams by connecting to separate data environments and business processes. For example, a system built on foundation models can power internal search for operations teams while also supporting customer-facing experiences.

Many organizations also use these systems for knowledge management. That allows employees across departments to access the same reliable information through one interface.

What are common first projects for custom LLM and RAG systems?

Organizations typically begin with focused use cases where AI can show value quickly. These may include internal knowledge assistants, document analysis tools, or automation inside support platforms.

At NOVA, we also help teams test GenAI solutions that assist employees in daily tasks. Our AI specialists work with stakeholders to identify use cases where AI can immediately improve productivity or access to information.

How does NOVA help organizations choose the right AI use case?

NOVA begins by understanding how teams currently work with data and where delays or manual research happen. From there, our team evaluates where an LLM agent or other AI capability could improve daily operations.

We also review available data and system connections. This early planning stage helps organizations avoid building tools that look impressive but do not actually solve real operational problems.

Can custom LLM systems work with existing APIs and business platforms?

Yes. Many organizations integrate AI directly into existing software environments. For example, RAG-powered assistants can connect with CRM systems, support platforms, internal portals, and APIs.

These assistants use retrieval queries, embeddings, and vector search to pull information from multiple sources. That way, employees can ask questions or complete tasks without changing their toolkit.

What happens after a proof of concept is completed?

After a successful prototype, the focus shifts to making the system reliable and scalable. This usually includes preparing the data pipeline setup, expanding integrations, and testing the AI system under real workloads.

Some organizations may also extend AI capabilities into areas such as customer service workflows or internal decision support systems. NOVA helps teams define the architecture and steps needed to move toward a production-ready deployment.

How long does it take to build a custom LLM or RAG solution?

The timeline depends on the complexity of the use case and the condition of the available data. Simpe prototypes may be built in a short period, while production systems take more planning and testing.

For example, preparing datasets may require techniques like document chunking or content segmentation to organize information properly. NOVA works with each client to define realistic milestones and delivery phases.



What makes a custom AI system easier for teams to adopt?

AI tools work best when they fit naturally into daily work. Systems designed for a support team or operations staff should operate inside the tools those teams already use. Many organizations also prioritize transparency and reliability so employees trust the system.

NOVA can design confident AI experiences supported by LLM strategy & advisory to ensure the solution is practical and easy for teams to use.
